(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

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

key to abort entry and return to 2VFO mode.

Start by selecting VFO mode then key in the frequency of 123.500

MHz, “mode and step size” are set to the default auto “AUT” (if not use the key sequence )

to place the AR8200 into VFO mode.

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!

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.

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”,

In the write protect menu, to toggle the status to “ON”, the default is off.

To accept the input and store the data to the specified location,

. The display will revert to 2VFO mode.

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.

Please refer to

section 7-8-6

of this manual for details on MEMORY BANK write PROTECT.

&Note: Memory channel write protect prevents accidental over-writing and deletion of specific

memory channels but does not prevent loss of data due to memory resizing or when using the optional external memory slot card.

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.

section 5-2

of this manual.

To recall memory channel “E25” (there is no need to push enter).

The “BANK/CH SEL” legend automatically appears when the first key is pushed to remind you that you are recalling memory channels in memory read mode. 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.

Section 5-4-1, 5-5

5-4-1 Memory channel review / hunt

From VFO mode to enter memory read “M.RD” mode.

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.

Section 5-5-1, 5-5-2, 5-6, 5-7

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 .

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

your memory data before resizing memory channels

ignored but if a whole memory bank is protected, resizing will be inhibited.

After selecting the resizing value ò to display the memory sorting menu, the legend “MEM SORTING” will be displayed, the following lines confirm the current and

sizes. to initiate the resizing process. The LCD will clear except for the words “MEM SORTING !!” with the exclamation marks flashing to indicate that the sorting process is in

operation… After sorting, the display returns to its previous condition (before the SCAN BANK menu was accessed).

&Important note: Memory sorting can take several minutes, do not switch the AR8200 off,

disconnect power, remove batteries or allow the batteries to fail during memory sorting or data corruption may occur.

(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.

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.

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.

the key to act as a short cut to 5 seconds (default).

The more often you check the priority channel, the greater chance you have of ‘catching’ activity, however the greater the interruption to normal monitoring.

to accept the input and exit the menu.

&Note: Priority interval time is also used for VFO SCAN timings.

Section 7, 7-1, 7-2

(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).

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).

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

the CASE SHIFT

key first.

If no data is available, the next bank with valid data will be recalled (empty memory banks are skipped).

To scan more that one memory bank at a time, please refer to the scan bank linking

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

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.

channels as you work through the menus.

If at least one memory channel has been tagged PASS, the third line from the bottom of the LCD will display a memory location such as “PASS-CH A17” with the “A17” simply confirming that at least one memory channel is tagged PASS. If no memory channels have been tagged PASS, the LCD will display “PASS-CH ---”.

To remove all memory PASS tags in one go , the legend “ be displayed to show that removal of pass tags is in process followed by “

7-6 Deleting memory channels

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.

to access the DELETE menu. the ò key three times to

display the menu item “DELETE MEM-BANK B00”. The LCD will display a memory bank location such as “MEM-BANK B00” with the “B00” being the last memory bank used. Use the ï ð ñ ò keys to select the desired memory bank for deletion, alternatively type in the required bank letter via the keypad (the

CASE SHIFT key will be required to access the lower case memory banks). If there are no channels which contain data in the selected memory bank, the LCD legend “B --“ will be displayed with

“B” being the current bank and “--“ indicating that no channels are available for recall or scan (as they are empty).

To delete all memory channels from the displayed bank . After a few seconds the LCD will display “DELETE MEM-BANK B--“ indicating that the selected bank no longer contains memory data.

To exit the menu and return to the standard display .

7-7 Scan bank link (scan group)

It is possible to custom define scan parameters for a single bank or group of memory banks.

Use the key sequence to access the “SCAN GROUP” menu. Bank “SCAN GROUP 0” contains a

default listing and cannot be overwritten (so displays “LINK OFF” on the bottom line of the LCD), banks 1 to 9 are available for custom programming.

Use the main dial or ï ð keys to select the SCAN GROUP number, for SCAN-GROUP numbers 1 to 9 the legend

“BANK LINK” will be displayed on the bottom line of the LCD indicating that programming is possible.

ò to move to the memory bank letters, then

reverse highlight the letters you wish to link together as a group of memory channels to scan using the

ï ð ñ ò keys, to mark desired memory banks, both upper and lower case letters may

be highlighted in the same group. The selected banks (which will form a large scan group) will be displayed in REVERSE contrast on the LCD.

It is also possible to use the keypad to quickly select the required banks for inclusion as a group, this saves having to use to toggle selection, The CASE SHIFT key is used to toggle

between the upper and lower case memory bank listings.

to accept the data input. (one or twice) to start scanning if the

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.

To change the active SCAN GROUP, access the SCAN GROUP menu using the key sequence ,

select the desired SCAN GROUP (0 to 9) using the main dial or ï ð keys then to accept the change and exit the menu.

If you group banks “B, E, F, a, h” as SCAN GROUP number “1”, then when any one of
