AR8200 SERIES II - hand portable radio receiver ADDENDUM (paperwork V1.0)

Due to continuous development of our products, the AR8200 SERIES II has been developed which differs from the original AR8200 in a few areas, please note the following changes to the AR8200 operating manual:

1 The front ‘ten-key’ keypad has been rearranged in line with customer requests placing the ‘0’ zero key underneath the

‘8’ eight key as standard practice with push button telephones. On page 9 section 1-5-1 of the English language operating manual, the graphic should now look like:

2 The AR8200 SERIES II now features a built-in TCXO (Temperature Controlled Crystal Oscillator) in place of the reference

crystal. This ensures the best levels of frequency stability and minimum spurii.

3 In place of the previous rubber covered compact whip aerial is a telescopic whip on a swivel base. This provides the very

best performance, especially on the VHF bands with the ability to adjust the length of the telescopic whip aerial to ‘peak’ received signal strength (the higher the frequency, the shorter the aerial). An alternative flexible smaller whip aerial (DA900) is available as an option where durability and smaller size is important. Please refer to page 7 section 1-4 of the English language operating manual, line two of the table should now read “telescopic whip aerial”

4 The relationship between level squelch and signal meter has been revised. This affects VFO SEARCH LEVEL SQUELCH

(page 47 section 4-4-3 of the English language operating manual), SCAN LEVEL SQUELCH (page 68 section 7-8-2 of the English language operating manual) and PROGRAM SEARCH LEVEL SQUELCH (page 84 section 8-7-2 of the English language operating manual).

In each case, the following table replaces that previously employed:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

8 13 18 24 29 35 39 44 50 55 58 62 71 77

The typical level at which the “

«” legend will be extinguished is now in the region of 5 - 60.

5 High capacity NiCads are supplied with the AR8200, to ensure that a completely full charge is established, please assume

the full charge time of 14 hours, this replaces the reference to 12 hours given on page 19 section 1-6-4 of the English language operating manual.

6 The design of the battery compartment and compartment cover has been revised to assist the easy replacement of batteries,

refer to page 16 section 1-6-1 of the English language operating manual. The cabinet colour of the AR8200 has also been changed from green to black.

14-1 CONFIG BEEP

The AR8200 emits confirmation ‘beeps’ while the keypad and side keys are used. A ‘HIGH’ pitched beep indicates correct operation while a ‘LOW’ pitched beep indicates that an error or unexpected entry has taken place. The volume of the beep is independent of the main volume control and can be separately defined. It is recommended that the beep facility be enabled, especially in the early days while gaining familiarity of the receiver.

Beep is setup in the CONFIG menu. To access the config menu . The first item in the

config menu is “BEEP”, the default is beep on with a volume level of 09. Use the main dial or ï ð keys to vary beep level between the range of OFF and 01 to 09 with 09 being the loudest. The

key may be used as a short cut to 05.

to accept the data and return to a standard display. Alternatively

to abort entry or ò to move to the next item on the config menu (LAMP).

14-2 CONFIG LAMP

The AR8200 is equipped with high intensity green LEDs to illuminate the LCD and front panel keypad when operating in areas of low level lighting.

While the AR8200 is switched on and connected to an external power source such as the charger or d.c. lead, the lamp will be PERMANENTLY ON and

when the AR8200 is switched off (when the batteries are being charged etc).

cannot be switched off

. The lamp will go out

106

Page 5

Section 14-2, 14-3

The lamp may be configured in three ways:

AUTO

This setting is relevant when operating from internal batteries only. The lamp will automatically illuminate when the front panel and side panel keys are used. The lamp will remain illuminated for a further five second after the last key push and will then switch off. This is a good compromise setting for best visibility and battery life.

CONT

This setting is relevant when operating from internal batteries only. The lamp will CONTinuously illuminate the front panel and side panel keys. The lamp will only extinguish when the AR8200 is switched off. Of course continuous operation of the lamp will drain the internal batteries more quickly.

OFF

This setting is relevant when operating from internal batteries only. The lamp remains permanently extinguished, this is useful to maintain maximum battery life when used in areas of high light levels.

The LAMP is setup in the CONFIG menu. To access the config menu

. ò to move the cursor to the “LAMP” selection point. Use the main dial or ï ð

keys to toggle the lamp between AUTO (default), CONT and OFF. The key may be used as a short cut to AUTO.

to accept the data and return to a standard display. Alternatively

to abort entry or ò to move to the next item on the config menu (CONTRAST).

14-3 CONFIG CONTRAST

The AR8200 is equipped with variable LCD contrast which is adjustable in 32 steps to provide best visibility under different viewing angles, extremes of ambient light & temperature (and between sets due to variation).

The default setting for contrast is 14. The display generally becomes too dark to read around 20 and too feint around 02, the key may be used as a short cut to 14.

The CONTRAST is setup in the CONFIG menu. To access the config menu

. ò twice to move the cursor to the “CONTRAST” selection point. Use the

main dial or ï ð keys to vary the contrast level to achieve best visibility.

to accept the data and return to a standard display. Alternatively

to abort entry or ò to move to the next item on the config menu (POWER-SAVE).

107

Page 6

Section 14-4

14-4 CONFIG Power save

The POWER SAVE facility may be used to help the receiver to operate for longer periods of time between battery recharging. Power save is default OFF to prevent confusion while the AR8200 is in a “dormant” cycle as the receiver is effectively asleep and only wakes up for short periods to check for activity before going to sleep and becoming dormant again.

&Note: While in a dormant state (waiting to cycle), the AR8200 behaves sluggishly.

When power save is ON, the AR8200 will automatically switch ‘off and on’ but the display will appear permanently on as only the AR8200 “receive” circuitry is switched off and on (switching the receiver off for short periods of time is what saves power!), the microprocessor is left on permanently but in a reduced operating condition.

When activated, two parameters may be varied to affect the way the receiver behaves, these are “DELAY” and “CYCLE”.

DELAY: This parameter determines how long the AR8200 will remain active before going to sleep and becoming dormant and is timed from when the squelch last closed or keypad was last used. The available range is 01 to 30 seconds plus OFF (default off). When OFF, the power

save does not operate. The key may be used as a short cut to OFF.

CYCLE: When the receiver becomes dormant (delay has expired), the cycle parameter determines how long the AR8200 will remain dormant before its ‘wake up’ period begins. If a transmission takes place while dormant it will be missed, if however a transmission occurs during the wake up period, the AR8200 will continue to monitor until the transmission ends and DELAY / CYCLE takes place again. The available range is 0.5 to 9.5 seconds (default 3.0

seconds). The key may be used as a short cut to 3.0 seconds.

The POWER SAVE parameters are setup in the CONFIG menu. To access the config menu

. ò three times to move the cursor to the POWER SAVE “DELAY” selection point. Use the main dial or ï ð keys to vary the delay value, the key may be used as a short cut to OFF.

ò to move the cursor to the POWER SAVE “CYCLE” selection point.

Use the main dial or ï ð keys to vary the cycle value, the key may be used as a short cut to 3.0 seconds.

to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (AUTO PWR-OFF).

14-5 CONFIG Auto power off

An auto power off facility is available to switch the AR8200 off automatically after a programmable period of squelch inactivity, this prevents the batteries from becoming flat when monitoring a completely inactive frequency.

&Note: Be careful how you use auto power off as it might catch you out one day (if a short

auto-power-off period has been set), auto power off setting is not cancelled with power off / on… if the AR8200 appears to switch itself off for no reason, check to make sure that you haven’t enabled auto power off (there is no associated LCD legend).

AUTO POWER OFF is setup in the CONFIG menu. To access the config menu . ò five

times to move the cursor to the “AUTO PWR-OFF” selection point. Use the main dial or ï ð keys to vary the time between 0.5 hours

to 9.5 hours in 0.5 hr increments, the key may be used as a short cut to OFF.

When the AR8200 squelch closes, the CPU will wait the length of time programmed in auto-power-off before automatically switching the AR8200 off. If the squelch opens again before auto switch off time has elapsed, the radio will not power down and the counter will be reset (i.e. an open squelch defeats auto power off).

to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (REMOTE BPS).

14-6 CONFIG REMOTE BPS

The REMOTE BPS menu is used to configure the RS232 computer control settings as it is important that they exactly match those of an associated computer connection or another AR8200 (connected via the option socket and optional leads).

The REMOTE BPS parameters are setup in the CONFIG menu. To access the config menu .

ò six times to move the cursor to the “REMOTE BPS” selection point. Use the main dial or ï ð keys to vary the RS232

baud rate between 4800bps, 9600bps and 19200bps. The

key may be used as a short cut to the default of 9600bps.

ò to move the cursor to the “RMT-ID” selection point. Use the main dial or ï ð keys change the AR8200 RS232 IDENTIFICATION ADDRESS when multiple units are connected to the

same port. It is possible to connect up to 99 units at once, each radio being assigned a different address. The value

is adjustable between 00 and 99, the default is 00. The key may be used as a short cut 00.

&Important note: It is extremely important to set the RMT-ID to 00 for normal operation

of the RS232 connection and clone of data between radios.

to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (FREQ DISP).

14-7 CONFIG FREQ DISP

It is possible to instruct the AR8200 NOT to display frequencies while in memory read, search and scan modes (should you wish for prying eyes not to see specifically what you are listening to). Liberal use of ‘text comments’ is recommended if you disable frequency display (turned it off) unless you choose to have really anonymous operation!

&Note: Frequency display will be provided in VFO and VFO search and VFO scan even with

the frequency display disabled.

The FREQUENCY DISPLAY parameters are setup in the CONFIG menu. To access the config menu .

ò eight times to move the cursor to the “FREQ DISP” selection point. Use the main dial or ï ð keys to toggle between ON and OFF. The key may be used as a short cut to ON (which is default).

to accept the data and return to a standard display. Alternatively

to abort entry or ò to move to the next item on the config menu (WRITE PROT).

14-8 CONFIG GLOBAL write protect

It is possible to globally write protect the entire AR8200 data storage, this prevents memory entry, search bank programming, loading of data via the option socket, loading of data from the optional EM8200 etc.

Use this feature carefully.

Should you wish to leave your AR8200 safe in the knowledge that no-one will ‘mess it up’ (well maybe!)… toggle global write protect on.

The global “WRITE PROTECT” status is setup in the CONFIG menu. To access the config menu

(15) Band scope

The AR8200 is equipped with a flexible band scope function which is capable of graphically displaying band activity. The maximum frequency span width is 10 MHz, you may zoom in on activity to a span width of 100 kHz. Centre frequency is displayed and a marker may be manipulated to ascertain the frequency of activity using the graphical display. One trace may be saved to memory for recall at a later time and may be overwritten at will. The trace may also be saved and loaded from the optional EM8200 external memory slot card.

&Note: Priority operation is disabled when the band scope is in operation. Audio is muted.

The optional RU8200 is inoperative when the band scope is in operation.

It is suggested that the band scope facility is ‘experimented with’ on a constantly active band such as VHF Band-II broadcast.

15-1 Starting the band scope

To start the band scope . The frequency span width will be set to 10 MHz with the last frequency displayed in 2VFO, search, scan or memory read mode being used as the centre frequency.

AUDIO IS MUTED.

The centre frequency is displayed in the top left of the LCD, one pixel will be missing from the centre of the graphical base line indicating centre frequency position.

A progress cursor which comprises of a single pixel on the graphical base line travels from left to right updating the band scope display… this confirms that the band scope is IN OPERATION (especially useful when a trace is simply being updated or no signals have been located).

The frequency span width is displayed in the upper right corner of the LCD, at default this is 10 MHz. The frequency marker legend “MKR” is displayed on the second line of the LCD, the marker is also

represented graphically by an upturned triangle (initially placed above-centre of the graphical trace). When first activated, the centre and marker frequencies are the same (but may be altered).

The graphical trace is built-up from left to right. If no transmissions are encountered the display will simply form a horizontal line around two pixels in height. When activity is located, vertical lines are produced on the LCD, the stronger the signal the higher the line.

&Important: To monitor the transmission of the marker frequency and hold the

key. The progress of the scope is halted when the key is held. Squelch setting

has no effect on the band scope trace.

15-2 Exit from band scope

To exit the band scope or or .

15-3 Setting frequency span width (waveform enlargement)

The frequency span width may be adjusted between the limits of 10 MHz (default) to 100 kHz using the ñ ò keys. The span widths available are:

10 MHz 35s for full trace approx. 5 MHz 20s for full trace approx. 2 MHz 10s for full trace approx. 1 MHz 6s for full trace approx. 500 kHz 3s for full trace approx. 200 kHz 6s for full trace approx. 100 kHz. 3s for full trace approx.

When the frequency span width is altered, the trace restarts. to refresh the trace from the start.

Resolution is 10 kHz with a 12 kHz IF filter selected (NFM or AM) so that one pixel represents 140 kHz at maximum signal strength

Resolution is 2 kHz with a 3 kHz filter (USB, LSB, CW)

15-4 Moving the marker

To move the marker position use the ï ð keys, the channel step will be dependant upon the span width resolution. To monitor the marker frequency and hold the key. The progress of the scope is halted when the key is held.

15-5 Marker to strongest signal (peak search)

To simplify operation, it is possible to ‘jump the marker’ to the strongest signal of the current graphical trace (peak search). and hold the key until the “«” legend is displayed indicating

that the marker is set to the strongest graphical signal. and hold the key to monitor the selected frequency. The ï ð keys may be used to hop between the strongest few transmissions.

to disable peak search, the “«” will be removed from the LCD.

&Note: If no signal is found above the background level (or if there hasn’t been time allowed

for a trace to form), peak search will not operate and an error beep will be emitted (if beep is enabled). This facility cannot be used with a span width of 100 kHz.

113

Section 15-6, 15-7, 15-8, 15-9

15-6 Entering a new centre frequency

To enter a new centre frequency, simply tap the wanted frequency into the keypad. The legend “CENTRE FREQ” will be displayed on the top line of the LCD with entry taking place on the second line.

To complete entry in MHz format . The marker will be automatically set to the centre frequency but the frequency span width will be unchanged.

15-7 Transfer of marker frequency to VFO

There are two ways in which the marker frequency may be transferred to VFO for long term monitoring.

Transfer to 2VFO retaining VFO data

to move marker frequency to 2VFO, receive mode and step

are those of the VFO.

Transfer to single VFO with 10 kHz tuning step

Hold the key then to transfer marker frequency to single VFO,

receive will be that used in VFO mode but the tuning step will always be 10 kHz to allow sensible re-tuning in VFO mode for best reception of the transferred marker frequency

15-8 Peak hold

The PEAK HOLD facility is used to build up an image of band activity over a period of time, the display is not totally cleared each time a trace is made, only strong signals are added.

To toggle PEAK HOLD on/off , the “HLD” legend confirms when peak hold is active.

The ï ð keys may be used to move the marker position and

key may be held to monitor activity on the marker

frequency.

15-9 Saving active trace to memory

To save the current trace to internal memory (for later retrieval)

. It is suggested that the peak hold facility

be employed before saving a trace so that it provides more meaningful information.

If the optional EM8200 is used, it possible to save four further traces to external memory. Refer to for further information regarding this feature.

15-10 Loading stored band scope traces from memory

Providing a trace has been previously stored to memory, it is possible to recall it to display using the key sequence . The legend “RCV” (in the place of “MKR”) indicates that a

stored trace is currently being displayed.

The AR8200 will no longer sweep the frequency range but the key may still be used to monitor the marker frequency. Key in a new centre frequency to return to a real time band scope.

It is possible to move the marker across the graphical trace using the ï ð keys. Waveform enlargement is available by changing the frequency sweep width using the ñ ò keys.

(16) Sleep ¹

It is possible to instruct the AR8200 to automatically switch-off after a predetermined time, this is particularly useful if you know that you may be called away from the receiver or listen to it while in bed and don’t want the batteries to become completely flat.

Use the key sequence to accesses the SLEEP menu.

Use the main dial, ï ð keys or key to toggle sleep on/off. For convenience SLEEP is default ON when this menu is

accessed so that you have simply to access and exit the menu for sleep to be activated.

Either to save the changes and exit the menu or ò to move the cursor to the sleep TIME menu. Use

the main dial to set sleep time in 1s increments or ï ð keys to increment in 10 seconds, the range is between 1 and 120 minutes,

is a short cut to 60 minutes (default).

The AR8200 will automatically switch off after the programmed time has elapsed.

To accept the data and activate sleep . The display will return to standard format and the circular CLOCK legend ¹ will be displayed to remind you that automatic power off will take place.

The next time that the AR8200 is powered on, the sleep facility will be automatically cancelled.

(17) Option socket

The option socket is mounted on the right hand side of the cabinet underneath the 12V d.c. input socket. The socket is protected from dust by a grey rubberised case stopper which is hinged toward the front of the cabinet. Gently lift the stopper from the rear edge to reveal the D-shaped metallic socket. Be careful to keep dust and dirt from this socket and to prevent liquid entering the AR8200 via this socket. Ensure that no conductive material is allowed to short circuit the socket which may damage the receiver.

The option socket has three main uses:

1. Connection of the optional CR8200 tape recording lead

2. Connection of the optional CO8200 data clone lead

3. Connection of the optional CC8200 computer control lead with level

shift (available with imperial (PC98) & metric (DOSV) screws)

Other signals are available via the option socket including detector output, mute and AGC. Typical pin-out of the optional leads are as follows:

RED +4.2V BLACK RXD BLUE GROUND BROWN MUTE ORANGE AGC SHIELD GROUND WHITE TXD YELLOW GROUND GREEN AUDIO OUT GREY DETECTOR OUT PURPLE GROUND

Section 17

Output levels are as follows:

MUTE CMOS (0V or 5V) AUDIO OUT Constant level into greater than 10k OHMS DETECTOR OUT Available in NFM & SFM, impedance 10k OHMS AGC 3.5V to 0.5V, impedance 10k OHMS RS232C TXD + RXD (levels to drive a level shift converter)

It is possible to copy data (clone) between two AR8200 receives using the optional CO8200 clone lead, no computer is required.

&Note: As clone of data takes a while, it is suggested that the receivers are connected to

external power or at least that the NiCads are FULLY charged while cloning data. Do not prematurely terminate the clone of data in any way or data corruption may occur… do not switch either AR8200 off, disconnect the CO8200 or disconnect power. Data can be copied in either direction but the EM8200 is not supported, only INTERNAL data can be copied between radios.

Connect each radio to the CO8200 lead and switch them on. The following table indicates the facilities available:

ALL DATA All data is transferred from one radio to the other

SEARCH BANK A specific search bank is copied to the same or different bank

ALL SEARCH All search banks are copied from one radio to the other keeping

MEM BANK A specific memory bank is copied to the same or different bank

ALL MEM All memory banks are copied from one radio to the other keeping

(approx. 8 minutes 30 seconds)

number of the second radio (approx. 3 seconds)

bank numbers the same (approx. 1 minute 30 seconds)

(18) Slot card socket

The slot card is located in the bottom of the AR8200 cabinet and protected from dust etc by a door which is hinged toward the back edge of the cabinet. To access the socket place the AR8200 on its back and open the front edge of the protective door. Be careful to keep dust and dirt from this socket and to prevent liquid entering the AR8200 via this socket. Ensure that no conductive material is allowed to short circuit the socket which may damage the receiver.

18-1 Optional slot cards

Any ‘one’ optional card may be fitted at any time. Do not use anything other than the ‘genuine’ AOR slot cards.

The slot card has five main uses:

1. VI8200 Voice inverter (analogue) in 157 steps

2. CT8200 CTCSS squelch & search

3. TE8200 Tone eliminator in 256 steps

4. RU8200 Chip based recording and playback, 20 seconds approx.

5. EM8200 External extended memory, backup 4,000 memories, 160 search

banks (can hold as much data as 4 x AR8200)

Signal types depend upon the slot card fitted, these include:

l 4.2V PSU l GROUND l CARD RECOGNITION l AUDIO IN l AUDIO OUT l CARD CONTROL IN l CARD CONTROL OUT

18-1-1 Fitting the slot card

Always switch the AR8200 off when inserting slot card.

the socket place the AR8200 on its back and open the front edge of the protective door. With the AR8200 keypad facing upward, hold the slot card so that its label also faces upward. An arrow printed on the slot card indicates the direction of entry into the AR8200, insert the connec- tor end of the slot card into the AR8200 (the end you will be left holding has groves to help grip). Without using excessive force, use a thumb to push the slot card fully into the body of the AR8200 until it is slightly recessed into the bottom of the receiver. Close the hinged slot card compartment cover.

To access

&Note: The AR8200 will automatically recognise each optional slot card, there is no need to

initialise the option (except for the EM8200, see later).

When slot cards are fitted, the AR8200 menu system dynamically changes to reflect the slot card

121

Section 18-1-1, 18-1-2, 18-2

currently fitted. If however the AR8200 ‘thinks’ that a slot card option is fitted when it isn’t, access the slot card menu and disable the option. You may wish to leave certain items selected if they are not affecting current operation in order to minimise reprogramming when slot cards are inter-changed at a later time.

18-1-2 Removing the slot card

Always switch the AR8200 off when removing a slot card.

socket place the AR8200 on its back and open the front edge of the protective door. An EJECT slider is mounted on the left hand side of the AR8200 cabinet. With the AR8200 keypad facing upward slide the EJECT control toward the side keys of the AR8200, the thumb is best for this purpose… hold the thumb of the other hand one or two centimetres (one inch) from the bottom of the slot card to prevent it shooting out of the AR8200 and falling on the floor.

The stiffness of the cards varies and may be tighter when used for the first few times, the EJECT slider needs quite a push but don’t use excessive force or tools!

To access the

18-2 VI8200 optional voice inverter slot card

The VI8200 enables the AR8200 to recover intelligible audio from certain types of analogue transmission which would otherwise sound scrambled. They operate by splitting up the audio spectrum and ‘flipping’ the upper and lower tones around a certain frequency point. The VI8200 enables 157 different ‘flip points’ to be selected in the frequency range of 2.4 kHz to 5.6 kHz.

Insert the VI8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have

recognised that the VI8200 has been fitted so will present the voice inverter menu.

The legend “VOICE INVERT” confirms selection of the voice inverter menu. the key to toggle the voice inverter on/off (default on). Use the main dial or

ñ ò keys to make selection of tone in 157 steps from 0 to 156, the ï ð keys are used to increment selection by 10.

To accept the data input (when audio is intelligible) , alternatively to abort entry

Refer to the relationship table between value and ‘flip’ frequency:

Frequency (kHz) 2.4 2.8 3.2 3.6 4.0 4.4 4.8 5.2 5.6 6.0 6.15 Inverter value 0 37 64 86 102 116 128 138 146 154 156

When the voice inverter has been activated and you exit from the voice inverter menu back to VFO, the legend “v 68” will be displayed in the bottom right corner of the LCD. The legend “v” indicates that the

122

Page 21

Section 18-2, 18-3. 18-3-1

inverter is active while the legend “68” indicates the current ‘flip’ value in use.

To speed up the toggling of voice inverter, to effectively toggle the voice inverter option on/off. This is

achieved as the default is set to voice inverter ON (by accessing the voice inverter menu) so that every time the voice inverter menu is accessed, the voice inverter is automatically activated.

1. For example, assume that the voice inverter is currently OFF. to access the voice inverter menu, the voice inverter

menu cursor will move to “ON”.

2. to revert to VFO mode with the voice inverter on.

3. to immediately toggle the voice inverter off.

The sequence then repeats each time you .

&Note: Using the voice inverter to monitor normal transmissions will

cause them to distort and sounds rather like tuning across a busy short wave band using USB.

18-3 CT8200 optional CTCSS slot card

The CT8200 enables the AR8200 to search for 50 CTCSS tones which may be in use on the current receive frequency and to save a specific CTCSS tone (from the 50 tones available) into each VFO, each search bank and every memory channel individually. CTCSS is used by many amateur band repeaters, public utilities and private mobile radio services where shared resources are used, CTCSS ensures that operators only hear traffic intended for them.

Insert the CT8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have recognised that the

CT8200 has been fitted so will present the CTCSS menu.

The legend “CTCSS” confirms selection of the CTCSS menu. the key or use the ñ ò keys to toggle the CTCSS facility between OFF / ON / SRCH (default is off). To abort entry and

exit the menu .

&Note: You won’t be able to audibly hear a CTCSS tone due to the low frequencies

employed and audio characteristics of the AR8200 (and other receivers).

18-3-1 CTCSS tone squelch

123

Page 22

Section 18-3-1, 18-3-2

While in the CTCSS menu, to activate the CTCSS facility (the LCD legend “ON” is displayed in reverse highlight).

Use the main dial or ï ð keys to make selection of CTCSS tone from the 50 available, the value cannot be adjusted when the menu is set to “OFF”. The current CTCSS tone is displayed on the

last-but-one line of the LCD, the legend “«” is displayed to the left of the CTCSS frequency when the current receive frequency is using the displayed CTCSS tone, this assists manual selection of

the correct tone.

To accept the data input , alternatively to abort entry . The selected CTCSS tone may

be used in VFO (separate CTCSS tones may be held in each VFO) and independent CTCSS tones saved in each search bank and memory channel.

While in VFO, the legend “CTC” is displayed in the lower left corner of the LCD to indicate that CTCSS is active. The audio will be completely muted until a transmission occurs which contains the specified CTCSS tone even when the squelch is set fully anti-clockwise (open), it is normal for the occasional ‘splutter’ to be produced as ‘CTCSS type fingerprints’ naturally occur in everyday transmissions and background noise.

Scan & search banks: It is even possible to scan & search with the squelch open when CTCSS is active but scan/search rates will be reduced significantly. To achieve the best speeds, set the squelch until the “S” legend is extinguished in the usual manner.

Refer to the CTCSS table of available tones:

94.8 100.0 103.5 107.2 110.9

114.8 118.8 123.0 127.3 131.8

136.5 141.3 146.2 151.4 156.7

162.2 167.9 173.8 179.9 186.2

192.8 203.5 210.7 218.1 225.7

233.6 241.8 250.3 67.0 71.9

74.7 77.0 79.7 82.5 85.4

88.5 91.5 97.4 69.4 159.8

165.5 171.3 177.3 183.5 189.9

196.6 199.5 206.5 229.1 254.1

To switch CTCSS off, access the CTCSS menu to highlight the legend “OFF” then .

18-3-2 CTCSS search

If you are uncertain what CTCSS frequency is in use, but you think there may be one present, you may

124

Page 23

Section 18-3-2, 18-4

use the CTCSS SEARCH facility to discover what frequency is employed.

Place the AR8200 into VFO mode then

to access the CTCSS menu.

to highlight the “SRCH” legend then to accept the input and exit

the menu. The LCD legend “CT-S” will be displayed in the bottom left corner of the LCD to indicate that CTCSS SEARCH is in operation. While in 2VFO mode, the standby frequency will be replaced with the legend “CTCSS 205.5 Hz” when a CTCSS tone of 205.5 Hz has been located, otherwise the appropriate CTCSS frequency will be displayed.

Each memory channel, VFO and search bank can hold different CTCSS frequencies and different settings of CTCSS squelch and CTCSS search (i.e. you can have CTCSS search active in VFO but CTCSS squelch active in memory channels).

If you are uncertain where CTCSS may occur and wish to experiment with CTCSS search, simply activate the CTCSS SEARCH facility while monitoring a broadcast frequency (such as Band-II) which has a rich audio range (playing music etc).

&Note: As CTCSS search has to check all 50 possible frequencies,

it may take up to 15 seconds for the CTCSS tone to be identified.

18-4 TE8200 optional tone eliminator slot card

The TE8200 enables the AR8200 to ignore certain transmission tones which would otherwise stop the scan and search processes. Pilot tones are often transmitted by public utility services and railways making their transmissions troublesome and fatiguing to monitor without the use of the TE8200. There are 256 values for the tone eliminator ranging from 0 to 255 representing a frequency range of 0.4 kHz to 4.2 kHz.

Insert the TE8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have recognised that the

TE8200 has been fitted so will present the tone eliminator menu.

The legend “TONE ELMT” confirms selection of the tone eliminator menu. the key to toggle the tone eliminator on/off (default off). Use the main

dial or ñ ò keys to make selection of tone in 256 steps from 0 to 255, the ï ð keys are used to increment selection of tone in increments of 10.

When selecting the value, the legend “«” will be displayed to

125

Page 24

Section 18-4, 18-5, 18-5-1

the left of the numeric value to indicate that the displayed tone value is contained in the current receive frequency, this greatly eases location of the offending tone frequency to allow scan and search to continue.

To accept the data input , alternatively to abort entry . When active, the LCD legend “T.EL”

will be displayed in the bottom left corner of the LCD. Refer to the table to reconcile value with frequency:

Frequency (kHz) 0.4 0.6 1.0 1.4 1.8 2.2 2.6 3.0 3.4 3.8 4.2 Tone value 0 70 160 190 210 220 230 237 240 245 248

- - - - - - - - - - 60 110 170 200 220 230 235 240 245 248 250

Tone eliminator setting and value may be held separately in each VFO, search bank and memory channel.

The squelch should be set to threshold in the usual manner. Operation continues as normal with the tone eliminator active, however if a transmission is encountered which contains a ‘pilot tone’ which matches the current setting of the tone eliminator, the squelch will close allowing the scan and search processes to continue… i.e. the AR8200 will NOT think that it has found an active receive frequency or blank carrier.

&Note: The tone eliminator does not remove whistles from the

loudspeaker, it purely allows scan & squelch to continue unhindered.

18-5 RU8200 optional record & playback slot card

The RU8200 enables around 20 seconds of audio to be recorded to a chip within the RU8200 for playback at a later time. The chip may be recorded to time and time again overwriting the previous recordings. The recording may be played back over and over, very useful if you have grabbed an interesting recording! The RU8200 may be used in VFO, scan, search and memory read modes.

Insert the RU8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have recognised that the

18-6 EM8200 optional external extended memory slot card

The EM8200 enables the whole 1,000 memory channels in 20 banks and 40 program search banks to be backed up to the EM8200. In fact the EM8200 can hold the entire contents of the AR8200 including environmental operating data and band scope FOUR times in EM8200 locations 0, 1, 2 &

3. It is not necessary to save ALL data, you can specifically choose what data is to be backed up and to which location.

127

Page 26

Section 18-6, 18-6-1

&Note: You cannot scan or search the backup information, data

must be loaded back into the AR8200 before these processes can be activated.

&Important note: Never remove the EM8200 with the AR8200 switched on, especially

while data is being saved / loaded to and from the AR8200 or data corruption may occur. Saving all data takes some time, it is recommended that external power be used while copying large volumes of data to / from the EM8200 (or at least be sure that the batteries are well charged). No liability in any form will be accepted in respect of data saved to / loaded from the EM8200 option.

&Note regarding write protect: If the write protect has been globally set to ON

(ALL PROTECT) in the configuration menu ( ), data load will be unsuccessful and no data will be loaded. Individual memory channel protect, memory

bank protect and search bank protect will be ignored during data load from the EM8200.

&Note regarding possible NOISE: A small increase in ‘noise’ may be noticed while the

EM8200 option is fitted inside the AR8200, this will disappear when the EM8200 is removed from the receiver. If signals are very weak or noise is a problem, temporarily remove the EM8200 option.

The following table indicates the data types which may be saved to / loaded from the EM8200:

1 ALL-DATA All memories, search banks, band scope and

2 ALL-MEM All memory channels 3 MEM-BANK One specified memory bank 4 ALL-SRCH All search banks 5 SRCH-BANK One specified search bank 6 B-SCOPE Band scope data

environment data

18-6-1 Initialising (formatting) the EM8200 before use

The EM8200 has been tested during manufacture but is not fully formatted. Before you use the EM8200 for saving real data, you must format the memory, this only needs to be carried out once in the life of the EM8200 (similar to formatting a computer disk drive).

To format the memory, simply execute a SAVE ALL to each of the four memory locations of the EM8200 (0, 1, 2 & 3).

If you do not format the memory, you will still be able to carry out SAVE ALL (item 1 in the table) but the specific data saves (items 2, 3, 4, 5 & 6 will not operate). If you do not format the memory and later attempt to use a specific memory save or load, an error beep will sound (if beep is enabled).

To access the COPY EXT-MEM menu (which is used for the EM8200 data save / load and has been selected dynamically in place of the COPY RS232C menu as the AR8200 recognises that the EM8200 is

fitted) . Four significant lines of menu are displayed:

(19) Trouble shooting

Should the AR8200 appear to act strangely, check out the following suggestions to see if the problem can be overcome. Failing this, switch off the AR8200, disconnect any external power connection and remove one battery from the radio (if you have batteries fitted). Wait for at least 30 seconds then re-fit

the battery (if in use) or re-connect the external power and switch the radio on again with a of the key.

Check to see if the problem has cleared.

19-1 Soft reset of microprocessor

If removing power and switching the AR8200 off / on does not help, try a soft reset of the microprocessor.

Soft reset is achieved by powering-up the radio with the key held, do not release the key until the opening message has performed and a frequency is displayed in 2VFO mode.

All scan & search environments are cleared, bank link is set off and the receiver frequency will be set to

88.000 MHz for both VFO-A and VFO-B. The beep will be enabled and set to default as will lamp and LCD contrast. All memory and search bank data will be intact.

19-2 Other trouble shooting suggestions

AR8200 will not power on. Check that the set is connected to external power (12V d.c.) or that

batteries are fitted and are fully charged.

There is no audio. It may simply be that the squelch is closed or volume is turned down. and hold the key and adjust the volume to a comfortable level. Ensure that no external loudspeaker,

headphone or earphone is in use. Check that the band scope is not in operation. AR8200 display is strange and there is no audio. Check that the band scope is not in operation,

19-3 Trouble shooting - Take note of the following

Select scan cannot operate in conjunction with mode scan. Select scan is disabled when priority is

engaged. Priority is disabled when the band scope is in operation. If a long DELAY time is set, priority ‘eats’

away at delay time causing it to shorten. If the optional CT8200 slot card is in use, CTCSS SEARCH cannot operate with priority engaged due to the required CTCSS search time being quite long.

137

Page 36

Section 20

When POWER SAVE is on, response from the AR8200 may be sluggish and there will be periods of no receive.

If the key is being used to display a frequency with FREQUENCY OFFSET in use, this offset frequency cannot be stored into memory.

The squelch may not operate promptly (as you may expect) when monitoring in USB, LSB, CW and NAM modes due the narrow bandwidths employed. This is a fundamental characteristic of the squelch circuit. Audio may remain even though the “S” squelch legend may have disappeared for a couple of seconds. It is suggested that LEVEL squelch be used as an alternative in this situation.

There are no internal operator adjustments. In the unlikely event of servicing being required,

please contact your dealer for technical assistance.

(21) Aerial (antenna), earths & propagation

The subject of aerial choice and earth can be quite complex. There are many advantages and disadvantages to consider before connecting an external aerial to your receiver. One interesting phenomena is that aerial theory and practice can be surprisingly different. Keeping common sense in mind it is one of the few remaining areas for listeners to easily experiment and often achieve fantastic results.

Whip aerial

The supplied semi-flexible whip aerial should give adequate results for general hand-held operation on the VHF and UHF bands. A longer wire aerial or telescopic whip should be considered for listening to the short wave bands. The AR8200 is supplied with a ferrite bar aerial for medium wave reception, for best results, rotate the receiver as the bar aerial is directional.

Mounting location

It is important to mount any external aerial as high as possible and in clear space although this is more important at VHF frequencies than for short wave. If possible the aerial should have a clear path to the horizon. Results are usually disappointing when an installation is in a loft space.

Long wire aerials

For short wave reception a random length of long wire approximately 10 to 20 metres in length forms a good compromise. The wire should be connected to the centre pin of a BNC plug then connected to the BNC aerial input on the top of the AR8200. If possible try to locate the receiver close to a window so that the wire has the shortest and most direct run from the rear of the receiver to the outside world.

Discone

For wide coverage in the VHF-UHF bands a compromise has to be met and the most popular aerial is a discone (AOR DA3000). Their appearance is like a large spider or umbrella without the covering material, the better models have about 16 elements. Typical usable coverage starts from about 25 MHz and extends continuously to 500 MHz 1300 MHz or even 2000 MHz. The coverage peaks and dips throughout it’s range as the elements interact to provide the widest possible coverage. Due to their necessary construction discone aerials are a little prone to “wind noise” due to vibration and possible damage in severe gales.

Filters

A VHF civil AIRBAND FILTER is available (ABF125), this will help minimise the possible effects of breakthrough when listening to VHF airband in Band-II VHF high signal areas or when connected to external aerials.

Earth systems

A separate EARTH connection made to the outer (braid) connector of the BNC plug may improve aerial efficiency and reduce noise. Suitable earth points include connection to a water pipe, central heating radiator or external earth rod. If fitting a separate external earth rod, consider the implications carefully if your mains supply uses Protective Multiple Earth (PME) system. If in doubt consult an experienced electrician. Connecting an external earth wire may greatly reduce the local noise encountered when listening on the short wave bands. It is very important to provide a good earth should you use an aerial tuning unit.

A short length of thick gauge earth wire may be connected to a nearby central heating radiator or water pipe but never use a gas pipe for earthing. Ideally a separate earth rod should be used but the length between the receiver and rod becomes restrictive, if too long the earth system may well “pick up” noise rather than remove it.

139

Page 38

Section 22

Propagation

VHF and UHF transmissions generally only propagate relatively short distances when compared to short wave signals. For all intents and purposes they may be considered as line-of-sight plus a bit.

Where as point to point communication between mobile users or when in built up areas may only be a couple of kilometres, aircraft at heights of 30,000 feet may be heard for many tens of kilometres (100 to 300 with the right conditions).

Unlike VHF and UHF transmissions which generally propagate only on a localised basis (to the horizon plus a small amount), short wave transmissions may travel for many thousands of kilometres. Depending upon the frequency in use, time of day, season of the year and sun spot activity, transmissions may propagate completely around the World.

Luckily the frequency spectrum of short wave is often reflected back down to Earth by the upper layer of the Earth’s atmosphere called the ionosphere. When the reflected signals reach the Earth again they may either be received or reflected back up into space. If lucky, they will be reflected by the ionosphere yet again down toward the Earth providing reception into another and possibly more distant location. Depending upon the time of day and desired skip distance, different frequencies will be selected by

Radio Amateurs and commercial users such as Oceanic Air Traffic.

(5) Memory channels & banks

It is convenient to store commonly used frequencies into a memory channel along with mode etc, this saves having to key the data in over and over again. Memory read is very straightforward and quick when compared to re-typing all data.

5-1 Memory channel overview

Think of memory channels as pages in a notebook each of which is numbered to identify it. Data may be written to each new page (memory channel) and each page may be overwritten with new data, they can be used over and over again. The AR8200 has 1,000 memory channels in addition to 10 ‘quick

memory’ channels and a priority channel.

Each memory channel may hold:

one frequency

receive mode

tuning step

step-adjust

frequency offset

attenuator setting

noise limiter status

AFC status

pass status

write protect

text comment of up to 12 characters

The alphanumeric comment may be used to ease identification at a later date and to provide text search facilities.

The 1,000 memory channels are divided into 20 banks, each initially having 50 channels. The memory banks are identified by letters A, B, C, D, E, F, G, H, I, J (upper case letters) and a, b, c, d, e, f, g, h, i, j (lower case letters) and initially numbered from 00 to 49.

Examples are “A00” for the first channel location in memory bank “A” and “A49” for the last memory channel in memory bank “A”. “e15” is the location of memory bank “e” (lower case) channel “15”.

During the manufacture and testing of the receiver, various test frequencies may be entered into the receiver’s memory banks so the memory locations may not be completely blank.

&Note: Where memory channels and banks are empty the indication “- - -” is often displayed.

The stored data may be quickly and easily recalled, changed or deleted using the memory recall, edit and delete facilities.

&Note:

to make the recalling and scrolling of memory banks fluent, if no data is stored, the AR8200 may take up to 5 or 6 seconds to respond when attempting to change memory bank while the CPU checks for data.

It is suggested that one or two frequencies be held in each memory bank

Page 40

Section 5-1, 5-2

Auto-store

When shipped from the factory, memory bank “J” is reserved for auto-store of memory channels from search mode. This is a useful facility to quickly build a list of active frequencies. Please refer to

section 8-7-5

Dynamic memory bank resizing

The lettered memory banks are regarded as a ‘pair’ making a total of 100 memory channels per bank, initially equally divided between the upper and lower case letters. It is however possible to reallocate the 100 channels in blocks of 10 channels between the same letters A/a, B/b, C,c etc This means that the initial 50/50 may be reallocated as 60/40, 70/30, 80/20, 90/10, or 10/90, 20/80, 30/70, 40/60. This ‘dynamic’ memory reallocation can be useful to optimise the memory layout where a large or small collection of frequencies need to be monitored without unnecessarily wasting memory banks with just a few channels occupied.

Write protect

It is possible to write protect individual memory channels to prevent accidental deletion, whole memory banks and a ‘global’ write protect facility are also available.

Memory backup

The data contents of memory and search banks are held in an flash-ROM so that no backup battery or capacitor is required for memory retention.

of this manual for further information regarding AUTO-STORE.

&Note: When the AR8200 is switched OFF, all VFO data will be automatically stored.

Should the NiCads (or dry batteries if in use) become completely exhausted, the last stored memory channel or last VFO data ‘may’ be lost if the AR8200 is not powered-down using the

key and insufficient power is available to save the data.

5-2 Storing VFO frequencies & data into memory

It is possible to save frequencies to the ten quick memories for simple recalling but for longer-term storage, the 1,000 main memory channels offer a better and more flexible system.

The process to save a displayed VFO frequency to memory is as follows:

a) In VFO mode, select the required frequency, mode, attenuator etc b) to initiate memory write

c) Use the keypad, main dial or ïðñò keys to select the desired memory location

(BANK and CHANNEL)

d) Add a text comment (optional) or delete an existing comment e) Add memory channel write protect (optional) f) Exit the menu to save the data to the specified memory location

Lets assume that you wish to store the frequency of 123.500 MHz (with the attenuator off, noise limiter off, AFC off) into memory bank “E” location “25” (E25) while in VFO mode with the text comment of

“AIRBAND”. If a mistake is made during programming, the

to select the desired frequency, the mode and step size will be automatically set by

the AR8200 microprocessor.

the key for more than one second to enter ‘memory input’ mode.

One line up from the bottom of the LCD will be the legend “M-WRITE” with the highlight cursor positioned to the left of the bank identification letter such as “j”. The microprocessor will automatically select the youngest free memory location.

You may change the bank identifier at this time by pushing the ï ð keys or by typing in a three digit memory location using the numeric keypad.

You will notice that to the right of the keypad numbers, there are small orange letters which are bank identifiers, available memory locations are A - J and a - j. Key 1 is “A”, key 2 is “B” etc, ignore the letters K - T as these are used in search mode only. The lower case bank identifiers may be accessed pushing the CASE SHIFT

key

Remember, if you take too long entering data (90 seconds) the display will revert to it’s original condition of 2VFO mode, if you are selecting the memory location via a three digit key sequence, you only have 2 seconds before the keypad times-out!

frequency.

to initiate ‘memory input’ mode.

Select the bank by pushing the ï ð keys and using the main dial for channel number, or by typing in a three character memory address using the numeric keypad.

Assuming that you wish to store 433.000 MHz into “d10” which acts as the CASE SHIFT key to select the lower case banks then to select bank lower case “d”. Next select the channel for “10”. If any data is already stored in location

“d10”, the bottom line of the LCD will flash with the stored frequency. You need to carry out this key sequence fluently within 2 seconds or the bank location will time out.

The 2 second time out does not apply when the bank and channel are selected using the main dial and ï ð keys.

Page 43

Section 5-2-1, 5-2-2, 5-3

To recap:

Once the three digit memory location has been selected, the 2 second keypad time-out does not apply to the rest of the sequence.

To add the text comment “70cm”, ò then use the main dial to select the text and the

ï ð keys to move position of text input. To accept the new frequency and text comment “70cm”,

5-2-2 Automatic memory allocation

When you to start the memory write sequence, the AR8200 will initially offer the first available empty memory location which has no data stored in it. to accept the

channel offered or choose another location as described in the previous sections. Alternatively you may

the ò key to add a text comment then complete memory write by pushing . If the

AR8200 has to look through many full memory channels before an empty channel is located, the message “MEM WRITE SEARCH BLANK CH” may be briefly displayed.

5-3 Memory write protect

As indicated in memory channels are not accidentally over-written. It is important to remember that by write protecting a memory channel, it may prevent certain facilities from being used (such as over-writing the memory channel or copying / swapping memory data to it).

The memory protect status may be assigned as the last stage of memory write (as per manual) or toggled on/off using the memory channel EDIT facility, refer to regarding memory channel EDIT facilities, in particular MEMORY PROTECT.

It is also possible to write protect a whole memory bank, this prevents accidental deletion of data when resizing memory banks.

5-4 Memory read “M.RD”

Once frequency and mode data has been stored into a memory location, its retrieval is quick and simple. Let’s assume that you wish to retrieve the frequency of 123.500 MHz which has been programmed into

to memory “E25” during an earlier example in the preceding

to place the receiver into memory read mode, the legend “M.RD” appears toward the

top left of the LCD to confirm operation. The AR8200 will monitor whatever memory channel first appears when you enter memory read.

The AR8200 will display memory channel, mode, frequency, tuning step, text comment (if one was used), attenuator status, noise limiter status and AFC status. The memory channel last used (for memory write or recall) will initially be displayed, If the desired memory channel is not immediately displayed it may be recalled by keying in the required three digit location.

Keypad memory recall requires a three digit location, one letter for the bank and two numbers for the channel. If you hesitate for more that 2 seconds while recalling memory channels via the keypad the sequence will time out, for more leisurely memory recall use the ï ð ñ ò keys.

To recall memory “b06” the CASE SHIFT key needs to be used to access the lower case bank,

(there is no need to push

enter). If you attempt to recall a memory which has no valid data (because it is blank) the next valid memory channel will be displayed instead. Blank memory channels are ignored.

The main dial may be rotated or the ñ ò keys pushed to review, hunt for and select memory channels one by one, channels with no data stored will be skipped. the ï ð keys to move between

memory banks one by one.

&Important note: It is suggested that each memory bank be programmed with at least one

memory channel otherwise the AR8200 may appear as the CPU has to check all memory channels for valid data, this is particularly noticeable if jumping between bank “A” and “j” (opposite ends of the AR8200 memory map).

slow or sluggish

when recalling banks

Memory read using the main dial and ï ð ñ ò keys is useful for reviewing memory contents and hunting for a specific channel if you forget where you stored it! Should you know the number of the required memory channel, the keypad method of memory recall will be much faster. The AR8200 will monitor whichever memory channel is displayed in memory read “M.RD” mode.

It is also possible to hunt for memory channels using the TEXT SEARCH facility, please refer to section 12-2 of this manual for further details.

5-5 Deleting memory channels

It is possible to over-write a memory channel with new data, edit the contents of a memory channel or delete the channel entirely. When in memory read mode, use the key sequence

to access the “MEM DELETE” menu. The LCD menu invites you to “PUSH ENTER”

to delete the current memory channel, to delete it or to abort. When deleted, the AR8200 increments to the next memory channel which contains data. It is also

possible to delete whole memory banks in one go using the DELETE menu. Please refer to the

section 10-3

of this manual relating to memory bank DELETE options.

5-5-1 Memory channel editing

It is possible to copy, move, swap and edit memory channels to assist the management of data. Please refer to

section 9

of this manual regarding the EDIT menu.

5-5-2 Adding text names to memory banks

To assist with memory management and identification, memory banks can be named. The SCAN BANK menu is used to add or edit memory bank names.

To access the SCAN BANK menu . The LCD will initially display the legend “M-BANK”, the currently selected memory bank ‘pair’ (i.e. D/d or A/a or C/c etc) and the current

size allocation for the bank displayed i.e. B:50 b:50 for memory bank “B/b” with the allocation of 50 channels for “B” and 50 channels for “b”, this split of 50/50 being the default.

Use the main dial, ï ð keys or numeric keypad to select the required bank you wish to add a name to.

the ò key to move to the “BANK TEXT” menu.

Use the ñ ò keys to move between upper and lower bank identifiers, add text using the main dial and ï ð keys or use the keypad. To save the data and exit the menu .

5-6 Transfer of memory channel to VFO

While in memory read, should you wish to tune away from the memory channel and benefit from not having to re-enter the frequency, mode etc, the data may be quickly transferred from memory to ‘VFO’ mode.

To transfer memory channel data to VFO simply . The LCD will display the legend “VFO” along with receive frequency, receive mode, tuning step size and other relevant information such

as attenuator, noise limiter and AFC status. You may monitor the frequency or tune away from it using the main dial or ï ð ñ ò keys.

5-7 Dynamic memory bank resizing

The lettered memory banks are regarded as a ‘pair’ making a total of 100 memory channels per bank, initially equally divided between the upper and lower case letters. For example memory bank “A” will have 50 channels numbered from 00 to 49 (A00 - A49) and memory bank “a” will also have 50 channels numbered from 00 to 49 (a00 - a49) making a total of 100 channels.

It is possible to reallocate the 100 channels in blocks of 10 channels between the same letters A/a, B/b, C,c etc This means that the initial 50/50 may be reallocated as 60/40, 70/30, 80/20, 90/10, or 10/90, 20/80, 30/70, 40/60. This ‘dynamic’ memory reallocation can be useful to optimise the memory layout where a large or small collection of frequencies need to be monitored without unnecessarily wasting memory banks with just a few channels occupied.

The SCAN BANK menu is used to customise many features including memory bank resizing. To access the SCAN BANK menu .

Page 47

Section 5-7, 6

The LCD will initially display the legend “M-BANK” , the currently selected memory bank ‘pair’ (i.e. D/d or A/a or C/c etc) and the current size allocation for the bank displayed i.e. A:50 a:50 for memory bank “A/a” with the allocation of 50 channels for “A” and 50 channels for “a”, this split of 50/50 being the default. Use the main dial, ï ð keys or numeric keypad to select the required

bank for resizing. the ò key to move to the “BANK TEXT” menu where a text comment may be added

(optionally) to ease identification of each bank (use the ñ ò keys to move between upper and lower bank identifiers).

the ò key to move on to the resizing menu. The LCD will display the upper and lower case

identifiers on the same line with the current default allocation of 50/50 channels per bank. Use the main dial or ï ð keys to reallocate the channels in increments of 10 channels (60/40, 70/30, 80/20, 90/10, or 10/90, 20/80, 30/70, 40/60).

&Note: If you resize a memory which currently contains 50 channels to a new size of 10

channels, the last 40 channels will be deleted and data will be lost! Potentially when you resize memory banks, programmed data may be lost so it is suggested that you

(6) Priority operation

The PRIORITY feature enables you to carry on scanning, searching or monitoring while the AR8200 checks a frequency taken from one of the 1,000 memory channels (A00 default) every 5 seconds (default) for activity.

The priority checking is accomplished by momentarily moving to the priority frequency to see if it is ‘active’. If activity is found, the receiver remains on the frequency until the signal disappears. If no activity is detected, the receiver returns to the VFO frequency, scan channel or search bank from where it originated. The priority facility has a large number of applications and is particularly useful for keeping an eye on a distress frequency while scanning or searching another frequency band.

&Note: Depending upon the frequency and mode stored as priority, an audible

‘click’ may be heard when the priority facility is in operation. This is quite normal and is caused by the internal switching of circuitry necessary to accomplish the frequency change as two frequencies cannot simultaneously be monitored by the receiver.

Page 48

Section 6, 6-1, 6-2

&Note: The priority mode is automatically suspended during entry of frequencies via the

keypad, this prevents the receiver from changing frequency while you are busy programming. Priority operation is disabled when the band scope is in operation.

6-1 Engaging PRIORITY channel

Once engaged, the default channel used for PRIORITY is “A00” and the frequency contained is checked for activity every 5 seconds.

First ensure that there is data stored in memory channel “A00”.

To engage the priority facility , this may be carried out while in SCAN, SEARCH or VFO modes. The legend “PRI” is displayed in the top left hand corner of the LCD to indicate

that PRIORITY IS ENGAGED (switched on). If activity is encountered on the priority channel, the AR8200 will stay on the priority frequency until the

transmission ends (and the squelch closes) after which time the priority frequency will be checked for activity every few seconds.

&Note: Once priority has been activated, the data contents of the memory channel used

(default A00) may be altered without affecting the data used for PRIORITY operation which is stored separately and assumes an identity of its own irrespective of the data contents of memory A00.

Should you subsequently wish to alter the priority data, you will have to use the “PRIO SET” menu detailed in of this manual.

To cancel priority operation (which acts as a toggle), the legend “PRI” will be removed from the LCD.

section 6-2-1

6-2 Changing PRIORITY channel data

The default channel used for PRIORITY is “A00” and the frequency copied from this channel is checked for activity every 5 seconds. You may select a different memory channel from which the data will be copied or may vary the sampling time for priority activity checking.

Page 49

Section 6-2, 6-2-1, 6-2-2

This is accomplished by using the “PRIO SET” menu accessed by the key sequence .

The legend “PRIO SET” appears on the top line of the LCD to confirm selection.

6-2-1 Changing the priority channel data pickup channel

Should you wish the priority channel to use data contained in another memory location, access the “PRIO SET” menu using the key sequence , the legend “PRIO SET”

appears on the top line of the LCD to confirm selection. Select the new location for data pickup by the priority channel, use the main dial to move through the

memory locations one at a time or use the ï ð keys to move between banks, alternatively quickly key in a three digit memory location via the keypad.

For example, select memory location “A23” using the key sequence .

The priority interval time menu may be accessed using the ò key or to exit the menu. The newly nominated channel data will be used for priority monitoring.

&Note: If you attempt to nominate a channel which contains no data, the input will be

ignored and the previously used data will continue to be employed.

6-2-2 Changing priority interval time

Should you wish to check the priority frequency more or less often, the sampling time (interval) may be set using the “PRIO SET” menu. Use the key sequence to access the

“PRIO SET” menu. the ò key to move the cursor to the “INTERVAL” input line.

Use the main dial to vary the interval time in increments of 1 second, the ï ð keys may be used to vary the interval time in increment of 10 seconds. Priority time may be varied between the range of 1s to 99s.

(7) SCAN - scanning memory channels & banks

The AR8200 has a SCAN mode whereby the contents stored in the MEMORY CHANNELS ARE AUTOMATICALLY RECALLED AND MONITORED very quickly for activity - scanned.

* It is important that you do not confuse SCAN and SEARCH modes. *

SEARCH mode (covered later in this manual) automatically TUNES THE RECEIVER

THROUGH ALL FREQUENCIES between two specified frequency limits

looking for active frequencies.

7-1 SCAN - outline introduction

During SCAN, the AR8200 automatically recalls each memory channel which contains data in numeric order and monitors it looking for activity. When an ‘active’ memory channel is located (when a signal is found and the squelch is open) the AR8200 will temporarily stop scanning.

At default when shipped from the factory, the AR8200 will remain on the active memory channel until the received signal disappears and the squelch closes. The CPU will then wait a further 2 seconds in case a reply is audible (such as aircraft and air traffic communications) and will then resume scanning the memory channels again.

If the ñ ò keys are pushed or the main dial rotated (while scanning or when stopped on an active channel), the receiver resumes scanning in the direction of the arrow key or rotation. This is particularly useful for taking a second look a channels which have just been scanned.

Additional facilities available in SCAN

Memory banks may be “LINKED” and “UNLINKED” to effectively make larger or smaller groups of memories which may be scanned together.

“PASS” may be used whereby memory channels can be skipped when not required (such as when permanently busy), they may be easily reinstated at a later time.

“AUTO STORE” reserves memory bank “J” so that active frequencies found while conducting a SEARCH may be automatically written to memory. This is a useful tool for compiling an activity list of rarely used frequencies especially when unattended. Refer to information relating to auto store.

It is possible to alter the sequence of scanning events using the SCAN ENVIRONMENT menu. There are several scanning parameters which may be changed to suit your preferences and requirements DELAY, LEVEL, VOICE, FREE & MODE, it is possible to mix combinations of all parameters.

section 8-7-5

of this manual for further

7-2 SCAN considerations

It is presumed that you have already stored your favourite and commonly used frequencies into the memory banks (as per

A total of 1,000 memory channels are provided which are divided into 20 banks, each (at default) having 50 channels. The memory banks are identified by letters A, B, C, D, E, F, G, H, I, J (upper case letters) and a, b, c, d, e, f, g, h, i, j (lower case letters) and numbered from 00 to 49.

section 5-2

of this manual).

Page 51

Section 7-2, 7-3

When in SCAN MODE, the memory banks are referred to as “SCAN BANK A”, “SCAN BANK B”, “SCAN BANK f” etc rather than using the full title “SCAN MEMORY BANK A”, “SCAN MEMORY BANK B” etc. This terminology has been employed to make the explanation of and referral to SCAN MEMORY BANKS (SCAN BANKS) less long-winded.

When shipped from the factory, memory bank “J” is reserved for auto-store of memory channels from search mode so may already have frequencies stored.

Keep your memory banks tidy - for best scan speed

In order to achieve the maximum scanning speed, it is advisable to keep all similar frequencies and modes grouped together within the memory banks. The greater the frequency change between memory channels, then the further the receiver’s VCO (Voltage Controlled Oscillator) has to travel and the slower the scan rates. Similarly, when many changes of mode are called, more switching has to be accomplished and the scan speed may be reduced.

Memory channel data may be entered in duplicate into several channels. This will ensure the

channel data is scanned more frequently to increase the chances of activity being detected.

Limitations of SCAN mode

Should a number of different modes and wide range of frequencies be used, then the SCAN process may be affected by noise or differences in squelch characteristic on some frequencies and modes.

To help provide the best operation of SCAN, additional facilities have been provided (configurable via the SCAN ENVIRONMENT menu). Should you listen to noisy frequencies or bands containing carriers, make liberal use of the AUDIO, LEVEL and FREE scan facilities.

7-3 Starting to SCAN

Presuming that some memory channels are programmed with data, to start the scan process will take one or two pushes of the key depending upon which operating mode is currently employed

(in VFO and search mode the first press accessed memory read):-

Memory read mode “M.RD” VFO mode “VFO” or “2VFO” Search mode “SRCH”

The legend “SCAN” is displayed toward the top left of the LCD to indicate that the SCAN process has been started, a bank letter will also be displayed representing the current bank. Ensure that the

squelch control is advanced clockwise to threshold point so that background noise is cancelled and the squelch closes (otherwise scan will not operate).

Page 52

Section 7-3, 7-3-1, 7-4, 7-5

When SCAN has been selected, only the currently displayed memory bank WHICH CONTAINS DATA will be SCANNED (as bank link is default off), receive mode and frequency are unimportant. Any memory channels which contain no data (empty) will be ignored (skipped).

7-3-1 Transfer of active memory to VFO

When the scan process is paused on a busy channel, to transfer the current memory frequency to VFO where it may be monitored.

7-4 Selecting a scan bank

The memory bank identifier (such as “A”) will be displayed on the left of the LCD under the legend “SCAN”. If more than one memory channel is programmed into the current memory bank the channel numbers will be changing.

When an ‘active’ channel has been located (busy, so the squelch opens) the scan process will temporarily pause on the active channel, the memory location (such as “A03”) will be displayed along with any accompanying text (displayed underneath the memory location).

To select another memory bank for scanning, use the ï ð keys or

the corresponding letter on the

keypad from A to J, for lower case banks

7-5 Channel PASS

When scanning, you may encounter active memory channels which you do not wish to currently monitor. It is possible to manually force the scan process to continue by pressing the key or ñ ò keys

but this manual intervention can be an annoyance. For this reason it is possible to temporarily PASS

Page 53

Section 7-5, 7-5-1, 7-5-2

unwanted channels so that they are skipped when scanning. PASS does not delete the memory contents but simply ‘tags’ the channel to be skipped. In memory read, the PASS tag may toggled on/off and the tags removed in one operation using the delete pass channel facility of the DELETE menu.

While paused (during scan) on a busy channel which you do not currently wish to monitor, to skip it. The scan

process will immediately move on to the next memory channel of the current bank in the direction (up or down) which has been previously used for tuning or memory read. This tagged memory channel will be skipped during subsequent scans until the tag is removed. The legend “PAS” will have been assigned to the skipped memory channel which may be reviewed in memory read mode.

7-5-1 Toggling memory channel PASS

The key may also be used to tag (skip) unwanted channels when in memory read. To cancel channel pass tag on a particular memory channel, recall it in memory

read mode then . The LCD legend “PAS” indicates when the channel is locked out, the key toggles “PAS” on/off.

Although it is possible to over-write memory channels with new data, edit memory channels, swap, copy, move and to PASS (skip) them, there will be occasions when you want to delete memory channels completely.

7-6-1 Deleting single memory channels

While in memory read mode, to delete the currently displayed memory channel. As a safe guard against accidental deletion you will be instructed to to execute the deletion, alternatively to abort delete.

Once memory channels have been deleted, the data is destroyed and cannot be recalled again.

7-6-2 Deleting whole memory banks in one go

Should you wish to delete the entire contents of a memory bank, the DELETE menu may be used, this is quicker than recalling each memory in memory read mode and deleting them individually, especially if there are more than about five or six channels involved.

AR8200 is not already in scan mode. The memory banks grouped together in the SCAN GROUP will form a large group during scan. The SCAN GROUP number (and associated data) will be used to define current scan parameters.

For example:

these banks is scanned, all other banks in the group will be scanned in sequence over and over… B > E > F > a > h > B > E > F > a > h etc (providing each of the banks contains stored memory channels).

It is possible to scan ANY memory bank, even if it is not contained in the current SCAN GROUP list by manually selecting the bank using the ï ð keys or keypad while in scan mode.

You can individually configure each of the nine SCAN GROUPS 1 to 9 with a different collection of banks. SCAN GROUP 0 cannot be changed as it contains the default of LINK OFF so that you can quickly disable bank link when individual memory scan is required. SCAN GROUP 0 also contains default

settings for DELAY, LEVEL, VOICE, FREE and MODE parameters.

7-8-1 Scan DELAY

The scan DELAY parameter affects the time the AR8200 will remain on an active frequency in scan mode once the received signal has disappeared and the squelch has closed. This is particularly useful for customising how long the receiver will wait for a reply before resuming scan. For example, when communications are passed back and forth between a control tower / aircraft which may take a few seconds. The limits are OFF and 0.1 to 9.9 seconds in 0.1s increments (default 2.0 seconds).

7-8-2 Scan LEVEL

The scan LEVEL squelch parameter causes the AR8200 to check the signal strength and to only open the squelch when the signal strength is above the stated level (which is programmable in 256 steps). The limits are OFF and 1 to 255 (default off).

Scan LEVEL is configured via the SCAN-GROUP menu. Use the key sequence

The scan receive MODE parameter enables selected receive modes to be scanned in isolation even though memory banks may contain many different receive modes. This saves the need to lockout memory channels using the channel PASS facility when only a certain receive mode is desired (such as AM for airband monitoring etc).

Scan receive MODE is configured via the SCAN-GROUP menu. Use the key sequence

(8) Search mode

In search mode, the AR8200 is programmed to automatically tune between two specified frequency limits looking for activity. Please refer to terminology of SEARCH.

section 1-3

of this manual if you do not fully understand the

8-1 Search types

The AR8200 is equipped with two types of search:-

VFO SEARCH = search from the current frequency in VFO mode. Please refer to

PROGRAM SEARCH = search between user programmed limits.

section 4-3

of this manual for further information.

8-1-1 Program search overview

There are 40 program search banks (referred to simply as search banks) which can be programmed with specific parameters:

l LO (lower) start frequency l HI (upper) stop frequency l Receive mode (or set to AUTO MODE) l Receive tuning step (or set to AUTO MODE) l Step adjust l Frequency offset l Attenuator status l Noise limiter status l Text comment l Write protect l CTCSS tone (if the CT8200 SLOT CARD option is used)

The program search banks are identified by upper case letters A - T and lower case letters a - t. To help with identification, each bank may be labelled with an alpha-numeric text comment.

Page 63

Section 8-1-1, 8-2, 8-2-1, 8-2-2, 8-2-3

To assist testing in the factory, several search banks may be programmed with data (which can be easy deleted or over-written). This pre-programming is useful to ease familiarisation during the early days of operation… so that when you push a key there is something already programmed to work!

8-2 Starting program search

Presuming that data is already stored into a search bank…

the key to start the program search

process. The LCD legend “SRCH” will be displayed and as long as the squelch is closed, the search process will start from the lower frequency limit and will progress toward the upper frequency limit. When the program limit is reached, the search loops around and starts the process again.

&Note: If no search banks have been

programmed, the search process will not operate.

8-2-1 Reversing the direction of search

To reverse the direction of search use the main dial or ñ ò keys, this is useful to enable you to search back over and over an interesting point of the search process.

8-2-2 Forcing the search to resume

If the AR8200 stops on an unwanted busy frequency, the key or use the ñ ò keys or main dial to force the search process to resume from the current frequency displayed.

8-2-3 Stopping the search

While the search process is in progress (not stopped), to stop searching and transfer the current frequency to the single VFO for monitoring or tuning from. To exit the search process

the key for memory read mode or the key for 2VFO mode (displaying the

data on-screen before search was started).

Section 8-2-4, 8-3

8-2-4 Copying an active frequency to the VFO or memory location

It is convenient to transfer an active frequency from search to VFO or memory for periods of extended listening.

Copy to VFO

When the search process is stopped on an active frequency, the key to transfer the current receive frequency to the single VFO where it may be monitored.

Write to memory

When the search process is stopped on an active frequency, the key to write the current receive frequency into the first available empty memory location (or you may select a specific

location from the 1,000 memory channels available).

8-3 Selection of search bank

There are 40 search banks, while searching use the ï ð keys to step through search banks which contain data, alternatively you may use the numeric keys (with assigned letters and shifts). If no data is programmed in the nominated search bank, the next bank containing valid data will be used.

Recalling search banks A - J is very simple involving only one key push, for this reason it is suggested that these banks are used for primary search tasks.

While searching, the numeric key corresponding to the required search bank:

A * B C D E F G H I J

* When bank “A” is selected via the keypad, a delay of around two seconds will be encountered before the key is acted upon, this is because the key also has a special ‘SHIFT’ command

status when selecting banks K - T and k - t.

Tip

instantly

Page 65

Section 8-3

Recalling banks K - T requires use of the ‘SHIFT’ command before the letter key, this ‘shift’

command is the use of the key before a second numeric key is pushed. You must key

quickly or bank “A” will be selected, the timeout while using the ‘shift’ key is around two seconds:

K L M N O P Q R S T

Recalling banks a - j requires use of the ‘CASE’ command before the letter key, this ‘case’ command (selecting upper or lower case bank

letters) is the use of the key before a second numeric key is pushed.

8-5 Locking out unwanted active frequencies (PASS)

It is possible to lock out (PASS) unwanted frequencies while in program search mode, this is useful to eliminate unwanted permanent transmissions. It is important to

understand the PASS facility before using the key or transmissions may be missed.

While stopped on an unwanted frequency , the search process will resume. It will appear that all frequencies are still searched, however locked out frequencies will be ‘passed over’, the

search will not stop on locked out frequencies but the squelch may momentarily open causing a short burst of audio before the frequency is passed… if several consecutive active frequencies are locked out, an audio ‘chuff… chuff… chuff…’ may be encountered.

Locked out PASS frequencies are assigned PASS CHANNEL NUMBERS, there are a total of 50 PASS channels for each search bank. Frequencies ± 10 kHz from the assigned pass frequency will be skipped, carefully consider the implications of locking out ± 10 kHz when using USB, LSB and CW. When you attempt to exceed the limit of 50 pass channels per bank an error beep will be emitted (if beep is enabled). The locked out frequency will be relevant to the current search bank only… i.e. if you lock out 124.500 MHz in search bank “A”, this frequency will not be locked out of any other search bank and may be searched as usual in any other bank.

8-5-1 Search pass menu

to start searching (if the AR8200 is not already in search mode). The banks grouped

together in the SERACH GROUP will form a large group during search. The SEARCH GROUP number (and associated data) will be used to define current program search parameters.

For example:

searched, all other banks in the group will be searched in sequence over and over… A > B > E > A > B > E > A > B > E etc (providing each of the banks contains search program data).

It is possible to search ANY bank, even if it is not contained in the current SEARCH GROUP list by manually selecting the bank using the ï ð keys or keypad while in search mode.

You can individually configure each of the nine SEARCH GROUPS 1 to 9 with a different collection of banks. SEARCH GROUP 0 cannot be changed as it contains the default of LINK OFF so that you can quickly disable bank link when you wish to search only one bank. SEARCH GROUP 0 also contains default settings for DELAY, LEVEL, VOICE and FREE parameters.

8-7-1 Search DELAY

The search DELAY parameter affects the time the AR8200 will remain on an active frequency in search mode once the received signal has disappeared and the squelch has closed. This is particularly useful for customising how long the receiver will wait for a reply before resuming search. For example, when communications are passed back and forth between a control tower / aircraft which may take a few seconds. The limits are OFF / HOLD and 0.1 to 9.9 seconds in 0.1s increments (default 2.0 seconds).

1-1 Introduction

Thank you for purchasing the AR8200 hand held wide band all mode receiver. The AR8200 is designed using the very latest technology to ensure the highest levels of performance and reliability. To get the best possible results from your AR8200 we recommend that you read this manual and familiarise yourself with the receiver. Although carefully designed, this receiver (like all receivers) suffers from a degree of internal noises known as spurii. They are a product of the receiver’s circuitry and do not represent a fault. Apparent faults may be due to accidental misoperation of the receiver, if you think there is a problem, carefully read all of the manual before deciding to contact your equipment supplier for advice.

It is acknowledged that sections of this manual are repetitive, this is to enable the manual to be used as a reference book (you don’t have to read it all from cover to cover in one go). Due to the international nature of the product, some graphics contain Japanese characters.

Every effort has been made to make this manual correct and up to date. Due to continuous development of the receiver and by error or omission anomalies may be found and this is acknowledged.

© This manual is protected by copyright AOR Ltd 1998. No information contained in this manual may be copied or transferred by any means without the prior written consent of AOR Ltd. AOR and the AOR logo are trade marks of AOR Ltd. All other trade marks and names are acknowledged. E&OE

1-2 Take care of your radio

There are no internal operator adjustments. In the unlikely event of servicing being required, please contact your dealer for technical assistance.

Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to avoid locations where excessive heat, humidity, dust and vibration are expected. Always keep the AR8200 free from dust and moisture. Use a soft, dry cloth to gently wipe the set clean, never use abrasive cleaners or organic solvents which may damage certain parts. Treat the AR8200 with care, avoid spillage or leakage of liquids into the receiver and a.c. charger. Special care should be taken to avoid liquid entering around the controls, through the speaker grille or via the connection jacks.

The AR8200 is designed for operation from internal batteries or from its supplied a.c.-to-d.c. charger. Operation is possible from any good quality regulated d.c. supply of 12 to 14V, which should be capable of supplying 300mA. Never connect the AR8200 directly to the a.c. supply.

The d.c. input socket uses a mini 1.3mm power connector. This connector is configured CENTRE POSITIVE, the chassis of the receiver is at negative ground. The charger supplied is pre-wired and provides a nominal 12V d.c. output with suitable connectors being fitted as standard for the a.c. power input and connection to the AR8200.

SAFETY NOTICE - Always disconnect the charger from the a.c. socket when not in use.

If using the AR8200 in a base station situation, the best short wave reception is usually achieved by the fitting of a separate external earth rod, however consider the implications carefully if your a.c. building supply uses a Protective Multiple Earth (PME) system. If in doubt consult an expert electrician. Never earth to a gas pipe!

The AR8200 has a single BNC aerial socket for all frequencies. This is intended for connection to its supplied whip aerial or a 50 OHM (unbalanced) coaxial fed aerial such as a discone, dipole, unipole, yagis etc. When sighting the aerial, avoid power cables.

Section 1-2, 1-3

Operating anomalies

Should the AR8200 appear to behave strangely, normal operation may be easily achieved by resetting the microprocessor. Two scenarios may be encountered due to power transients etc:

Symptom: Action:

remove one NiCad battery and count to thirty! Re-fit the battery and press the power switch again. Normal operation should be restored but the last used frequency will be lost, the AR8200 will restore the last but one frequency to display.

2. Symptom: The AR8200 fails to power up.

Action: Try the suggestion given in (1) then hold the key while powering up

the AR8200 to ‘Soft reset’ the microprocessor.

LCD remains on, no control of the keypad.

Remove any connection to external power such as the charger or cigar lead,

1-3 Attention while operating

1. Certain key operations are acted upon when the key is RELEASED, not while it is pressed. Allow

time for the AR8200 to register such actions before pressing another key.

2. The keylock is intentionally made to be To release keylock, the key has to be held for more than one second, the key legend on the LCD confirms operation. The key is disabled during keying sequences (such as when

entering frequencies).

3. If a key sequence is not completed, the microprocessor will automatically abort most operations after about 90 seconds of keypad inactivity.

4. Currently displayed VFO data is saved at power down (to increase speed of operation and to reduce write cycles). For this reason, if the AR8200 is powered down by removing external supply (without internal batteries in place or when the batteries become exhausted), the last displayed frequency will be lost and the frequency used prior to this will be displayed when next powered up.

Terminology - Search & Scan

If you have not used a wide range monitor before or are not familiar with the terminology used, it is very important to understand the difference between SEARCH and SCAN modes.

SEARCH: The AR8200 provides several operations where transmissions (active frequencies) may be automatically located by sweeping the receiver over a wide frequency range, either from the currently displayed frequency travelling upwards (or downwards) in a specified tuning increment (step) or by sweeping over-and-over between two specified frequency limits. This process is known as SEARCHING, as the title implies, it can take a long time to find transmissions due to their ‘often intermittent’ and brief nature. For this reason it is best to slice large frequency ranges into smaller, more manageable pieces where they may be intensively studied. When examining large frequency bands, it is common to find that 90% of frequencies are inactive and only a small number of the remaining constitute what you really want. Searching still remains the best way to initially locate active and interesting transmissions (in conjunction with a good frequency listing and band plan).

SCAN: Once active transmissions have been identified (either by searching or by using a good frequency guide), it is more efficient to store the data into memories which can be rapidly and automatically monitored in succession stopping when activity is encountered. This forms a much

difficult to operate

to prevent accidental operation.

more efficient means of monitoring the most wanted frequencies as you have targeted 100% what you most want to hear, by contrast searching is very inefficient for day-to-day monitoring.

active frequency when the squelch opens and “S” ‘squelch open’ legend is displayed to the left of the signal meter. Advance the squelch control clockwise until the background noise is just cancelled, this is known as the threshold position. If the squelch control is advanced too far, weaker signals may be missed.

It is very important that the squelch is advanced to cancel background noise for the

This is because the AR8200 believes that it has found an

No noise and no “S” legend (with squelch advanced clockwise passed threshold) = squelch closed.

Signal received or ‘noise’ emanating from speaker (squelch fully anti-clockwise, below threshold) with no “S” legend = squelch open.

1-4 Accessories supplied

The following items are provided in the carton box:

1 x AR8200 receiver

1 x Whip aerial in BNC connector

1 x Medium Wave (MW) bar aerial

4 x AA NiCad batteries

1 x Charger (may be supplied in a separate cartons in some world market areas)

1 x Cigar adapter lead (containing internal 1A fuse)

1 x Hand strap

1 x Belt hook with two screws

1 x Operating manual (this booklet)

How to fit the hand strap

The hand strap anchor is located on the right hand side of the AR8200 cabinet. The hand strap comprises of two loops, one large and one small. Feed the small loop through the anchor then feed the large loop through the small loop and gently pull until tight. This strap is designed to be looped over your wrist to prevent the AR8200 from contacting the ground if accidentally dropped, it is not intended as a hard wearing utility… do not swing the set or abuse the set using this hand strap.

The MW bar also has a fixing hole so that you may tie it down to prevent loss.

How to fit the belt hook

The belt hook is a shaped metal plate with two fixing holes on the top edge, two fixing screws are provided. Do not use any other screws… if you attempt to use longer screws, the internal parts may be permanently damaged rendering the AR8200 inoperative. Offer the belt hook to the rear of the AR8200, locate and align the fixing holes then carefully fit the two supplied screws, fit both screws before tightening with a cross-head screwdriver.

Keypad conventions

Most keys have multiple functions, their functions are printed on the cabinet. However due the restriction of available size, not all facilities can be shown on the keypad printing. To ease access to the many facilities, two formats are employed:-

Push and release the key quickly to access the required facility. This applies to

primary facilities of keys such as numeric 1, 2, 3 etc. Also for example, quickly the

key while in 2VFO mode to toggle between the two VFOs VFO-A and VFO-B.

Press and HOLD the key for more than one second to access the second

function, sometimes this is in conjunction with the key.

Function key manipulation

The key also may be used by PUSH and PRESS depending upon the specific

requirement, in most cases however the key will require a simple PUSH.
