FT-270R OPERATING MANUAL

INSTALLATION OF ACCESSORIES

ANTENNA INSTALLATION

The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies.

To install the supplied antenna, hold the bottom end of the antenna, then screw it onto the mating connector on the transceiver until it is snug. Do not over-tighten by use of extreme force.

Notes:

Never transmit without having an antenna connected.

When installing the supplied antenna, never hold the upper part of the antenna while screwing it onto the mating connector on the transceiver.

If using an external antenna for transmission, ensure that the SWR presented to the transceiver is 1.5:1 or lower, to avoid excessive feedline loss.

INSTALLATION OF FNB-83 BATTERY PACK

The FNB-83 is a high-performance Ni-MH battery providing high capacity in a compact package. Under normal use, the FNB-83 may be used for approximately 300 charge cycles, after which operating time may be expected to decrease. If you have an old battery pack which is displaying capacity which has become diminished, you should replace the pack with a new one.

Installation of the battery is easy and quick:

Insert the battery pack into the battery compart-

ment on the back of the radio while tilting the Belt Clip outward, then

close the Battery Pack Latch until it locks in place with a “Click.”

To remove the battery,

turn the radio off and remove any protective

cases. Open the Battery

Pack Latch on the bottom of the radio, then slide the battery downward and out from the radio while tilting the Belt Clip out of the way.

8	FT-270R OPERATING MANUAL

INSTALLATION OF ACCESSORIES

BATTERY CHARGING

If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Cable (with its cigarette lighter plug) or E-DC-6 DC Cable (plug and wire only) may also be used for charging the battery.

A fully-discharged pack will be charged completely in 10 hours. Disconnect the NC-88 from the EXT DC jack and the AC line outlet.

NC-88

E-DC-5B

E-DC-6

Important Note

The NC-88 is not designed to power the transceiver for operation (reception or transmission).

Do not leave the NC-88 connected to the transceiver for continuous periods in excess of 24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly shorten its useful life.

Please be advised that the NC-88 may contribute noise to TV and radio reception in the immediate vicinity, so we do not recommend its use adjacent to such devices.

LOW BATTERY INDICATION

As your battery discharges during use, the voltage will gradually become lower. When the battery voltage is becoming too low for reliable operation,

the “ ” icon will blink on the LCD display, indicating that the battery pack must be recharged before further use.

Avoid recharging Ni-MH batteries before the “”indicator is

observed, as this can degrade the charge capacity of your Ni-MH battery pack.

FT-270R OPERATING MANUAL

INSTALLATION OF ACCESSORIES

BELT CLIP INSTALLATION

Connect the hanger to the rear of the FT-270R, with the notch pointing directly up, using the supplied screw (Figure 1). Use only the screw included with the clip to mount the clip to the back of the FT-270R.

Clip the Quick-Draw Belt Clip onto your belt (Figure 2).

To install the FT-270R into the Quick-Draw Belt Clip, align the hanger with the QuickDraw Belt Clip, and slide the FT-270R into its slot until a click is heard (Figure 3).

To remove the FT-270R from the Quick-Draw Belt Clip, rotate the FT-270R 180 degrees, then slide the FT-270R out from the Quick-Draw Belt Clip (Figure 4).

Figure 1	Figure 3

Figure 2

Figure 4

INSTALLATION OF FBA-25A ALKALINE BATTERY CASE (OPTION)

The optional FBA-25A Battery Case allows operation of the FT-270R using six “AA” size Alkaline batteries.

When installing batteries, insert the (–) end first, then press in the (+) end so the battery snaps into place. Always replace all six batteries at the same time, paying attention to the polarity indicated inside the case.

The FBA-25A must not be used with rechargeable cells. The FBA-25A does not contain the thermal and over-current protection circuits (provided in the “FNB” series of Ni-MH Battery Packs) required when utilizing Ni-Cd and Ni-MH cells.

Note that the power output and battery life will be much shorter when using Alkaline AA cells. They should be considered an emergency backup power source only, for this reason.

10	FT-270R OPERATING MANUAL

INTERFACE OF PACKET TNCS

The FT-270R may be used for Packet operation, using the optional CT-91 Microphone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail- able connectors wired to your TNC. You may also build your own cable, using a fourconductor miniature phone plug, per the diagram below.

The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as with voice operation. The input level to the FT-270R from the TNC should be adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms.

Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver.

When you are operating on Packet, switch the Receive Battery Saver OFF, as the “sleep” cycle may “collide” with the beginning of an incoming Packet transmission, causing your TNC not to receive the full data burst. See page 60 for details regarding Battery Saver setup.

FT-270R OPERATING MANUAL

OPERATION

Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the FT-270R. I know you’re anxious to get on the air, but I encourage you to read the “Operation” section of this manual as thoroughly as

possible, so you’ll get the most out of this fantastic new transceiver. Now. . .let’s get operating!

SWITCHING POWER ON AND OFF

Be sure the Battery Pack is installed, and that the battery is fully charged. Connect the antenna to the top panel ANTENNA jack.

Rotate the top panel’s VOL/PWR knob (inner knob) out of the click-stop to turn on the radio. The current

DC supply voltage will be indicated on the display for 2 seconds. After this 2 second interval, the display will resume its normal indication of the operating frequency.

To turn the radio off, turn the VOL/PWR knob fully counter-clockwise into the click stop position.

ADJUSTING THE AUDIO VOLUME LEVEL

Rotate the VOL/PWR knob (inner knob) to adjust the re- ceiver audio to a comfortable listening level, using the back-

ground noise as a reference. Clockwise rotation increases the volume level.

12	FT-270R OPERATING MANUAL

OPERATION

SQUELCH ADJUSTMENT

To set the squelch, press the [F/L] key, followed by the MONI switch just below the PTT switch on the left side of the transceiver.

Now rotate the DIAL (outer knob) to find the lowest setting (“LVL 1” through “LVL 15”) that will just silence the background noise. Do not use a higher set-

ting than necessary, or sensitivity to weak incoming signals will be degraded.

Press the PTT switch momentarily when you’ve made

the new setting; this will return you to normal operation (without having transmitted).

1) A special “RF Squelch” feature is provided on this radio. This feature allows you to set the squelch so that only signals exceeding a certain S-meter level will open the squelch. See page 18 for details.

2) If you’re operating in an area of high RF pollution, you may need to consider “Tone Squelch” operation using the built-in CTCSS Decoder. This feature will keep your radio quiet until a call is received from a station sending a carrier which contains a matching (subaudible) CTCSS tone. Or, if your friends have radios equipped with DCS (Digital Coded Squelch) like your FT-270R has, try using that mode for silent monitoring of busy channels.

FREQUENCY NAVIGATION

The FT-270R will initially be operating in the “VFO” mode, a channelized system which allows free tuning throughout the currently-selected operating band.

Three basic frequency navigation methods are available on the FT-270R:

1) Tuning Dial

Rotation of the DIAL (outer knob) allows tuning in the pre-programmed steps established for the current operating band. Clockwise rotation of the DIAL causes the FT-270R to be tuned toward a higher frequency, while counter-clockwise

rotation will lower the operating frequency.

If you press the [F/L] key momentarily, then rotate the DIAL, frequency steps of 1 MHz will be selected. This feature is extremely useful for making rapid frequency excursions over the wide tuning range of the FT-270R.

OPERATION

FREQUENCY NAVIGATION

2) Direct Keypad Frequency Entry

The desired operating frequency may be entered directly from the keypad. The first “1” in the frequency does not need to be entered, as it is “assumed” by the microprocessor.

To enter a frequency directly, just key in the 10 MHz, 1 MHz, and the kHz digits.

Examples:To enter 146.560 MHz, press [4] [6] [5] [6] [0]

To enter 146.5625 MHz (12.5 kHz steps), [4] [6] [5] [6] [2]

3) Scanning

Press and hold in either the [ (MHz)] or [ (MHz)] key for one second to initiate upward or downward scanning, respectively (Manual VFO Scan).

For scanning within a limited sub-band range, from the VFO mode, press and hold in the [6(A/N)] key for one second to begin scanning toward a higher frequency within the previ- ously-defined sub-band (Programmed VFO Scan). Details regarding sub-band setup may be found on page 37.

If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a higher frequency), just rotate the DIAL one click in the counter-clockwise direction while the FT-270R is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL one click clockwise.

(MANUAL VFO SCAN)

(PROGRAMMED VFO SCAN)

The scanner will stop when it receives a signal strong enough to break through the Squelch threshold. The FT-270R will then hold on that frequency according to the setting of the “RESUME” mode (Set Mode Item 32: RESUME). Press the PTT switch momentarily to cancel the scanning. This only stops the scan; it does not cause transmission to occur. See page 38 for details regarding Scan Operation.

Once you have set up an appropriate frequency inside the 144 MHz Amateur band on which the FT-270R can transmit, you’re ready to go on the air! These are the most basic steps; more advanced aspects of transmitter operation will be discussed later.

To transmit, press the PTT switch, and speak into the front panel microphone (located in the lower left-hand corner of the speaker grille) in a normal voice level. The TX/BUSY indicator will glow red during transmission.

To return to the receive mode, release the PTT switch.

During transmission, the relative power level will be

indicated on the bar graph at the bottom of the LCD;

full scale deflection confirms “High Power” operation, while deflection of two bars indicates “Low Power” operation. Five bars indicate “Medium Power” operation. Additionally, the “LOW” icon will appear at the bottom of the display while operating on the “Low Power” and “Medium Power” settings.

1) If you’re just talking to friends in the immediate area, you’ll get much longer battery life by switching to Low Power operation, described in the next chapter. And don’t

forget: always have an antenna connected when you transmit.

2) Transmission is possible only on the 144 MHz amateur band.

Changing the Transmitter Power Level

To change the power level:

Press the [F/L] key, then press the [3(LOW)] key. The LCD shows the current power output level.

Rotate the DIAL knob to select the desired power output level. Available selections are “HIGH” (5 W), “MID” (2 W), and “LOW” (0.5 W).

When you have made your choice, press the PTT switch to save the new setting and return to normal operation.

“LOW” POWER

“MID” POWER

“HIGH” POWER

1) The FT-270R is smart! When you store memories, you can store the power output settings separately in each memory, so you don’t waste battery power when using very close-in repeaters!

2) When you are operating on the “Low” or “Medium” power setting, you can press the [F/L] key, then press the PTT switch, to cause the FT-270R to transmit (temporarily) on High power. After one transmission, the power level will revert to the previously-selected (“Low” or “Medium” power) setting.

REPEATER OPERATION

Repeater stations, usually located on mountaintops or other high locations, provide a dramatic extension of the communication range for low-powered hand-held or mobile transceivers. The FT-270R includes a number of features which make repeater operation simple and enjoyable.

REPEATER SHIFTS

The FT-270R has been configured, at the factory, with the repeater shift set to 600 kHz.

Depending on the part of the band in which you are operating, the repeater shift may be either downward (–) or upward (+), and one of these icons will appear at the top of the LCD when repeater shifts have been enabled.

AUTOMATIC REPEATER SHIFT (ARS)

The FT-270R provides a convenient Automatic Repeater Shift feature, which causes the appropriate repeater shift to be applied automatically whenever you tune into the designated repeater sub-bands in your country. These sub-bands are shown below.

If the ARS feature does not appear to be working, you may have accidentally disabled it.

To re-enable ARS:

1.Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.

2.	Rotate the DIAL knob to select Set Mode Item 4: ARS.
3.	Press the [F/L] key momentarily to enable adjustment of this
	Item.
4.	Rotate the DIAL knob to select “ARS. ON.”
5.	When you have made your selection, press the PTT switch to
	save the new setting and return to normal operation.

FT-270R OPERATING MANUAL

REPEATER OPERATION

MANUAL REPEATER SHIFT ACTIVATION

If the ARS feature has been disabled, or if you need to set a repeater shift direction other than that established by the ARS, you may set the direction of the repeater shift manually.

To do this:

1.Press the [F/L] key, then press the [4(RPT)] key to enable selection of the repeater shift direction.

2. This provides a “short-cut” to Set Mode Item 35: RPT.MOD. 3. Rotate the DIAL knob to select the desired shift among “RPT.–,”

“RPT.+,” and “RPT.OFF.”

4.When you have made your selection, press the PTT switch to save the new setting and return to normal operation.

If you make a change in the shift direction, but still have Automatic Repeater Shift still engaged (see previous section), when you change frequency (by rotating the DIAL knob, for example) the ARS will over-ride your manual

setting of the shift direction. Turn ARS off if you do not wish this to happen.

If you make a change in the repeater shift on a memory channel that you already stored, the radio will consider this a “temporary” change unless you store the memory once more, this time with the desired repeater shift engaged.

Changing the Default Repeater Shifts

If you travel to a different region, you may need to change the default repeater shift so as to ensure compatibility with local operating requirements.

To do this, follow the procedure below:

1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 41: SHIFT.

3.Press the [F/L] key momentarily to enable adjustment of this

Item.

4. Rotate the DIAL knob to select the new repeater shift magnitude.

5.When you have made your selection, press the PTT switch to save the new setting and return to normal operation.

If you just have one “odd” split that you need to program, don’t change the “default” repeated shifts using this Set Mode Item. Enter the transmit and receive frequencies separately, as shown on page 29.

REPEATER OPERATION

MANUAL REPEATER SHIFT ACTIVATION

Checking the Repeater Uplink (Input) Frequency

It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if the calling station is within direct (“Simplex”) range.

To do this, just press the [REV(HOME)] key. You’ll notice that the display has shifted to the repeater uplink frequency.

Press the [REV(HOME)] key again to cause operation to revert to normal monitoring of the repeater downlink (output) frequency. While you are listening on the input frequency to the repeater using the [REV(HOME)] key, the repeater offset icon will blink.

The configuration of this key may be set either to “RV” (for checking the input frequency of a repeater), or “HM” (for instant switching to the “Home” channel for the band you are operating on). To change the configuration of this key, use Set Mode Item 33: REV/HM. See page 77.

VFO SPLIT MODE

For working on repeaters with odd splits, or communicating with astronauts on orbiting space vehicles, it may be necessary to use non-standard splits between the receive and transmit frequency. If the application is infrequent enough not to warrant the dedication of a memory channel for this purpose, the “VFO Split” mode may be used. Here is the procedure for going Split:

1.Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the desired receiving (downlink) frequency (e.g.145.800 MHz).

2.Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit (uplink) frequency (e.g. 144.490 MHz).

3.Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive) VFO.

4.Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.

5. Rotate the DIAL to select Set Mode Item 50: VFO.SPL.

6. Press the [F/L] key, then rotate the DIAL to set this function “VSP. ON.”

7.Press the PTT switch once to save the new setting and exit to

normal operation. 8. You will now be operating in the Split mode. When you press

the PTT switch to transmit, you will observe that VFO-A and

VFO-B will reverse positions. The VFO selection indicator “-b-” will blink while the transceiver is transmitting, this means that the VFO Split feature is now activated.

REPEATER OPERATION

VFO SPLIT MODE

9.If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction, etc.), just press the [VFO(PRI)] key, then make the necessary change, then press [VFO(PRI)] key once more to restore VFO-A to the “receive VFO” position.

10.When you have finished with Split operation, re-enter the Set mode, and change Set Mode Item 50: VFO.SPL to “VSP.OFF.”

A split frequency pair set up via the VFO Split feature cannot be stored directly into memory. You can, however, store odd frequency pairs using a different (slightly simpler) procedure. See page 29.

22	FT-270R OPERATING MANUAL

CTCSS/DCS/EPCS OPERATION

CTCSS OPERATION

Many repeater systems require that a very-low-frequency audio tone be superimposed on your FM carrier in order to activate the repeater. This helps prevent false activation of the repeater by radar or spurious signals from other transmitters. This tone system, called “CTCSS” (Continuous Tone Coded Squelch System), is included in your FT-270R, and is very easy to activate.

CTCSS setup involves two actions: setting the Tone Mode and then setting of the Tone Frequency. These actions are set up by using the [1(SQ TYP)] key and [2(CODE)] keys.

1.Press the [F/L] key, then press the [1(SQ TYP)] key to enable selection of the CTCSS/ DCS/ECSmode.

2.Rotate the DIAL knob so that “TONE” indication appears on

the display; this activates the CTCSS Encoder, for access to repeaters requiring a CTCSS tone.

3.Rotation of the DIAL knob one more “click” in step “2” above

will cause the “TSQL” notation to appear. When “TSQL” is displayed, this means that the Tone SQueLch system is active, which mutes your FT-270R’s receiver until it receives a call from another radio sending out a matching CTCSS tone. This can

help keep your radio quiet until a specific call is received, which may be helpful while operating in congested areas of the band.

1) You may notice a “REV TN” indication on the display while you rotate the DIAL knob in this step; this means that the Reverse Tone Squelch system is active, which mutes your FT-270R’s receiver (instead of opening the squelch) when it receives a call from the radio sending a matched

CTCSS tone. The “” icon will blink on the display when the Reverse Tone Squelch system is activated.

2) You may notice the “DCS” and “ECS” indications on the display while you rotate the DIAL knob still more. We’ll discuss the Digital Code Squelch system (for “DCS”) and Enhanced Paging & Code Squelch (for “ECS”) later.

4.When you have made your selection of the CTCSS tone mode, press the PTT switch to save the new setting.

5.Press the [F/L] key, then press the [2(CODE)] key to enable adjustment of the CTCSS fre-

quency. 6. Rotate the DIAL

knob until the dis-

play indicates the Tone Frequency you need to be using (ask the repeater owner/
