Installation

This chapter describes the installation procedure for integrating the FT-90R intoa typical amateur radio station. It is presumed that you possess technical knowl-edge and conceptual understanding consistent with your status as a licensedradio amateur. Please take some extra time to make certain that the important safetyand technical requirements detailed in this chapter are followed closely.

Preliminary InspectionInspect the transceiver visually immediately upon opening the packing carton.Confirm that all controls and switches work freely, and inspect the cabinet for anydamage. Gently shake the transceiver to verify that no internal components havebeen shaken loose due to rough handling during shipping.

If any evidence of damage is discovered, document it thoroughly and contact theshipping company (or your local dealer, if the unit was purchased over-the-counter)so as to get instructions regarding the prompt resolution of the damage situation.Be certain to save the shipping carton, especially if there are any punctures orother evidence of damage incurred during shipping; if it is necessary to return theunit for service or replacement, use the original packing materials but put theentire package inside another packing carton, so as to preserve the evidence ofshipping damage for insurance purposes.

Installation TipsTo ensure long life of the components, be certain to provide adequate ventilationaround the cabinet of the FT-90R.

Do not install the transceiver on top of another heat-generating device (such as apower supply or amplifier), and do not place equipment, books, or papers on topof the FT-90R. Avoid heating vents and window locations that could expose thetransceiver to excessive direct sunlight, especially in hot climates. The FT-90Rshould not be used in an environment where the ambient temperature exceeds+60º C (140º F).


Installation

Safety InformationThe FT-90R is an electrical apparatus, as well as a generator of RF (Radio Fre-quency) energy, and you should exercise all safety precautions as are appropriatefor this type of device. These safety tips apply to any device installed in a well-designed amateur radio station.

Do not allow unsupervised children to play in the vicinity of your trans-ceiver or antenna installation.

Be certain to wrap any wire or cable splices thoroughly with insulatingelectrical tape, to prevent short circuits.

Do not route cables or wires through door jambs or other locations where,through wear and tear, they may become frayed and shorted to ground or toeach other.

Do not allow anyone to stand in front of a directional antenna while youare transmitting into that antenna, especially on UHF. Do not install a di-rectional antenna in any location where humans or pets may be walking inthe main directional lobe of the antenna’s radiation pattern.

In mobile installations, it is preferable to mount your antenna on top of theroof of the vehicle, if feasible, so as to utilize the car body as a counter-poise for the antenna and raise the radiation pattern as far away from pas-sengers as possible.

During vehicular operation when stopped (in a parking lot, for example),make it a practice to switch to the “MID2” or “LOW” power options if thereare people walking nearby.

Never wear dual-earmuff headphones while driving a vehicle.

Antenna ConsiderationsThe FT-90R is designed for use with antennas presenting an impedance of near 50Ω at all operating frequencies. The antenna (or a 50 Ω dummy load) should beconnected whenever the transceiver is turned on, to avoid damage that could oth-erwise result if transmission occurs accidentally without an antenna.

Ensure that your antenna is designed to handle 50 Watts of transmitter power.Some magnetic-mount mobile antennas, designed for use with hand-held trans-ceivers, may not be capable of this power level. Consult the antenna manufacturer’sspecification sheet for details.

Most all FM work is performed using vertical polarization. When installing adirectional antenna such as a Yagi or Quad, be certain to orient it so as to producevertical polarization, unless you are engaged in a special operating situation wherehorizontal polarization is used.

Note that this transceiver is designed with wide frequency coverage in the VHFand UHF spectra. For general listening, you may wish to have a broadband an-tenna such as a discone available, because a directional antenna such as a Yagiwill have degraded performance outside the Amateur bands.

Excellent reference texts and computer software are available for the design andoptimization of VHF and UHF antennas. Your dealer should be able to assist youwith all aspects of your antenna installation requirements.

Use high-quality 50 Ω coaxial cable for the lead-in to your FT-90R transceiver.All efforts at providing an efficient antenna system will be wasted if poor quality,lossy coaxial cable is used. Losses in coaxial lines increase as the frequency in-creases, so an 8-meter-long (25’) coaxial line with only ½ dB of loss at 28 MHzmay have a loss of 2 dB or more at 440 MHz; choose your coaxial cable carefullybased on the installation location (mobile vs. base) and the overall length of thecable required (for very short runs of cable in a mobile installation, the smaller,more flexible cable types may be acceptable).

Installation


Installation

For reference, the chart below shows approximate loss figures for typically-avail-able coaxial cables frequently used in VHF/UHF installations.

Loss in dB per 30 m (100 feet) for Selected 50 Ω Coaxial Cables(Assumes 50Ω Input/Output Terminations)

Loss figures are approximate; consult cable manufacturers’catalogs for complete specifications.

In outdoor installations, be certain to weatherproof all connectors thoroughly, aswater entering a coaxial cable will cause losses to escalate rapidly, thus diminish-ing your communications effectiveness. The use of the shortest possible length ofthe highest quality coaxial cable that fits within your budget will ensure the bestperformance from your FT-90R.

Mobile InstallationThe FT-90R must only be installed in vehicles having a negative ground electri-cal system. Mount the transceiver where the display, controls, and microphone areeasily accessible, using the supplied MMB-68 mounting bracket. The transceivermay be installed in any position, but should not be positioned near a heating ventnor anywhere where it might interfere with driving (either visually or mechani-cally). Make sure to provide plenty of space at the rear of the transceiver so thatair can flow freely through the heatsink. Refer to the diagrams showing properinstallation procedures.

Transceiver Installationr Choose a mounting location with sufficient clearance for the transceiver, plus

space for ventilation around the heat sink. Using the mounting bracket as a template for the mounting holes, use a 4.8 mm(3/16”) bit to drill the mounting holes, and secure the mounting bracket with thesupplied screws, washers, and nuts (see diagram).

r Position the transceiver in the bracket so that the holes in the side are alignedwith those in the bracket, and bolt the transceiver into place using the suppliedshort screws and flat washers.

Installation


Installation

Mobile Power ConnectionsTo minimize voltage drop and avoid blowing the vehicle’s fuses, connect thesupplied DC power cable directly to the battery terminals. Do not attempt to defeator bypass the DC cable’s fuse—it is there to protect you, your transceiver, andyour vehicle’s electrical system.

Warning!Never apply AC power to the power cable of the FT-90R, nor DC voltagegreater than 15.8 Volts. When replacing the fuse, only use a 15-A fast-blow type. Failure to observe these safety precautions will void the Lim-ited Warranty on this product.

r Before connecting the transceiver, check the voltage at the battery terminalswhile revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’svoltage regulator before proceeding with installation.

r Connect the RED power cable lead to the POSITIVE (+) battery terminal, andthe BLACK power cable lead to the NEGATIVE (-) terminal. If you need toextend the power cable, use #12 AWG or larger insulated, stranded copperwire. Solder the splice connections carefully, and wrap the connections thor-oughly with insulating electrical tape.

r Before connecting the cable to the transceiver, verify the voltage and polarityof the voltage at the transceiver end of the DC cable using a DC voltmeter.Now connect the transceiver to the DC cable.

Mobile SpeakersThe optional SP-7 or MLS-100 External Speakers include their own swivel-typemounting brackets, and are available from your Yaesu dealer.

Other external speakers may be used with the FT-90R, if they present the speci-fied 4-16 Ω impedance and are capable of handling the 2 Watts of audio outputsupplied by the FT-90R.


Base Station InstallationThe FT-90R is ideal for base station use as well as in mobile installations. The FT-90R is specifically designed to integrate into your station easily, using the infor-mation to follow as a reference.

AC Power SuppliesOperation of the FT-90R from an AC line requires a power source capable ofproviding at least 10 Amps continuously at 13.8 Volts DC. The FP-1023A, FP-1025A, and FP-1030A AC Power Supplies are available from your Yaesu dealerto satisfy these requirements. Other well-regulated power supplies may be used,as well, if they meet the above voltage and current specifications.

Use the DC power cable supplied with your transceiver for making power connec-tions to the power supply. Connect the RED power cable lead to the POSITIVE(+) power supply terminal, and connect the BLACK power cable lead to the NEGA-TIVE (-) power supply terminal.

Packet Radio Terminal Node Controller (TNC)The extremely compact size of the FT-90R does not allow the inclusion of adedicated packet interfacing jack. However, all connections required for either1200 bps or 9600 bps packet operation are provided, either on the front or rearpanel.

1200 BPS PACKET SETUP

1. Connect the TNC’s “Data In” (RX Audio) line to the EXT SP jack on the rearpanel of the FT-90R.

2. Connect the TNC’s Ground, “Data Out” (TX Audio), and PTT lines to Pins,, and of the right side MIC jack (see illustration).

TransmissionTo transmit, simply close the PTT (Push To Talk) switch on the microphone whenthe frequency is clear. Hold the microphone approximately 25 mm (1”) from yourmouth, and speak into the microphone in a normal voice level. When your trans-mission is complete, release the PTT switch; the transceiver will revert to thereceive mode.

Power Output SettingFour power output levels are available on this transceiver: 5 watts (L O W ), 10watts (M I D 2 ), 20 watts (M I D 1 ) and 50 watts (VHF) or 35 watts (UHF) on H I G H .

To change the power level, press the front panel’s [P2] button on the microphone.Each time you press the [P2] button, the new power level will be displayed for afew seconds, then the regular display mode will reappear.

The power level may be stored in a memory register, if desired.

PTT LockingThe PTT circuitry may be locked out, so as to prevent unauthorized or otherwiseundesired transmission.

To lock out the PTT and prevent transmission as following:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “1 9 L c k T x .”

2. Press the key to select the desired locking mode:

To cancel the PTT lockout feature, select “O F F ” in step 2 above.

Operation


Operation

Repeater SplitsThis transceiver offers three methods of setting up split frequency operationon repeaters:

• Manual selection of preset repeater shifts;

• Automatic Repeater Shift (ARS), providing automatic activation of repeatershifts during designated repeater frequency subbands; and

• Independently stored transmit and receive frequencies (typically not corre-sponding to established repeater frequency shifts).

Standard Repeater ShiftTo activate the repeater shift, just press the key. The available choiceswill appear in the following order with each press of the key:(A R S ) “Automatic Repeater Shift” ß (– ) “Minus” shift ß (+ ) “Plus” shift ß(O F F ) “Simplex” ß (A R S ) ...

With repeater shift activated, you can temporarily reverse the transmit and receive

frequencies by pressing the key. Use this feature to display the repeateruplink frequency without transmitting, and to check the strength of signals on theuplink frequency (so as to determine whether or not a particular station is within“Simplex” range, for example). The “r ” icon will appear at the bottom left side ofthe display while “Reverse” shift is activated.

The default repeater offsets are fixed at 600 kHz on the VHF band and 1.6/5.0/7.6 MHz on the UHF band (depending on your country’s requirements)from the factory. You can change the standard offset, if needed, using thefollowing procedure:1. Set the transceiver to the band on which you wish to change the standard re-

peater shift (VHF or UHF).


knob to select “3 0 S h i f t .”

3. Press either the or key to set the desired offset. Note that theresolution of the “standard” repeater shift is to the nearest 50 kHz multiple.


5. If you wish to change the standard offset on the other band, repeat steps 1through 4 above.


Automatic Repeater ShiftThe ARS (Automatic Repeater Shift) feature in the FT-90R allows easy and con-venient repeater operation by automatically activating the repeater shift functionwhenever you tune to a standard repeater sub-band. The ARS function is preset atthe factory to conform to the bandplans for the country to which it is exported.

The ARS function is enabled at the factory. To disable it:Press the key, as many times as necessary, so that “O F F ” appears on thedisplay.

To re-enable ARS:Press the key, as needed, to set the display to “A R S .”

ARS operation is independent on the VHF and UHF channels. Therefore, you areallowed to have ARS enabled on VHF but disabled on UHF, if you like.

Operation

Separate Transmit Frequency MemoriesAll memory channels can store independent receive and transmit frequencies, toaccommodate occasional “odd splits” (non-standard offsets) with greater fre-quency resolution than is available using the “standard” shift feature.

Memory system operation will be detailed in a later section; here is the procedurefor storing and recalling an “odd split” using a Memory channel:1. First store the receive (repeater output) frequency.

In the VFO mode, tune the transceiver to the de-sired receive frequency. Now press and hold inthe [VFO/MR] button on the microphone for onesecond. Notice that the display is now blinking.

2. Within five seconds of pressing the [VFO/MR]button, use the MAIN DIAL knob or microphone’s[UP ]/[DWN] buttons to select the desiredMemory channel for storage (occupied memorychannels will show the currently-memorized fre-quency, while open channels will be blank).

3. Now press the [VFO/MR] button momentarily tostore the receive frequency into the selectedmemory.

4. Next store the transmit (repeater input) frequency.Since you are still in the VFO mode, tune the trans-ceiver to the desired transmit frequency.

5. Now press and hold the [VFO/MR] button for one second. The display willagain blink.

6. Press and hold in the PTT switch, and press the [VFO/MR] button momentarilywhile holding in the PTT switch. This will not cause transmission, but rather itwill instruct the transceiver that you are programming a separate transmit fre-quency into memory.

7. If you tune off the displayed frequency, you can now return to the just-storedMemory channel by pressing the [VFO/MR] button momentarily.


Tone Squelch SystemsThese systems allow silently monitoring until a call directed to you is received,and offer privacy on an otherwise busy channel.

CTCSS (Continuous Tone Coded Squelch System)This system superimposes a continuous, subaudible (low-frequency) tone on yourtransmitted audio. When decoded at the other station, this allows their squelch toopen so as to receive your transmission. Some “closed” repeaters use this to limitaccess, or to prevent signals intended for other repeaters (with the same inputfrequency) in fringe areas from locking up the repeater. There are 47 selectableCTCSS tones.

DCS (Digital Code Squelch)DCS operation modulates a subaudible tone according to a digital protocol (con-tinuous 32-bit synchronous code). DCS is widely used in the commercial land-mobile industry because of its superior performance, and its 104 unique codesoffer greater tone selection than CTCSS.

To use either CTCSS or DCS, both stations must be on the same operating fre-quency, and must have selected the same CTCSS tone or DCS code.

To select and activate CTCSS or DCS operation:• Press the [P1] button to select the desired squelch type from the following:

m “E N C ” (Encode) appears when the CTCSS tone generator is activated fortransmission only.

m “E N C /D E C ” (Encode & Decode) appears when the CTCSS tone squelch isactivated for both TX & RX (only signals “encoded” with the matching tonewill open the squelch; your radio will remain silent otherwise).

m “B E L L ” (CTCSS Bell Paging) appears when CTCSS Bell Paging is acti-vated, as described in detail later.

m “D C S ” (Digital Code Squelch) appears when Digital Code Squelch system(TX & RX) is active.

m “O F F ” (No tone or digital code system activated)

• Wait a few seconds; the display will revert to its normal status, and your newCTCSS or DCS operating mode will be saved.

Operation


Operation

For the discussion below, let us assume that the [P1] key is in its default setting(selection of Tone options). If not, one of the programmable keys must be as-signed the “TONE” function, per the instructions on pages 47 and 48.

1. When you have chosen the desired operating frequency, press the [P1] keymomentarily. The display will indicate “O F F ” if no CTCSS or DCS code iscurrently engaged.

2. Within three seconds, press the [P1] key as many times as required to activatethe desired Tone mode. The available options are:

E N C (CTCSS Encoder) The current tone will be shown at the bottomof the display.

E N C /D E C (CTCSS Encoder/Decoder)The current tone will be shown at the bottomof the display.

B E L L (CTCSS Bell Paging) The current tone will be shown at the bottomof the display.

D C S (DCS Encoder/Decoder) The current DCS Code # will be shown at thebottom of the display.

O F F No CTCSS/DCS tone or code is active.

3. When you have made your selection from the above list, press the microphone’s[UP] or [DWN] key, as many times as required, to select the desired CTCSSTone Frequency or DCS Code #.

4. When you have completed your selections, wait until the “Tone Programming”display disappers; you may now resume normal operation. If you are workingon a Memory channel, you should re-memorize the changes you have just made.

Note:It is not possible to store a different CTCSS tone frequency or DCS code on theuplink and downlink of a repeater.


Operation

DCS Tone Search ScanningIn operating situations where you don’t know the DCS code being used by anotherstation, you can command the radio to listen to the incoming signal and scan insearch of the DCS code being used.

To scan for the DCS code in use:1. Set the radio up for the DCS operation.


knob to select “1 3 D C S .”

3. Press the key to start scanning for the incoming DCS tone.

When the radio detects the correct tone, it halts on that tone, and audio is allowedto pass. The tone code will be shown at the lower left side of the display, and youmay then set MENU #12 to the same DCS code, if you wish to store the frequencyinto memory.

Press and hold in the key for one second to exit to normal operation.

CTCSS Bell PagingBell Paging adds an alert ringer to CTCSS tone squelch operation, for added con-venience. When you receive a call with a matching CTCSS tone, the ringer soundsto alert you to the presence of the incoming call.

To activate CTCSS Bell operation, press the microphone’s [P1] button until “B E L L ”appears on the display.

As before, calls without a matching CTCSS tone will be ignored. Those with amatching tone will cause the transceiver to ring as the squelch opens while thecaller transmits. Note that other stations do not need to have the CTCSS Bellfunction to call you; they can just use standard CTCSS encoding.

When you reply to a CTCSS Bell call, you may want to turn off the Bell function,or else the transceiver will ring every time your squelch opens.

You can store CTCSS Bell Paging as a “tone mode” in a memory, as you can dowith different CTCSS/DCS tone and encode/decode states.

1750 Hz Tone Calling (European Versions)In the European versions of the FT-90R, press the [ACC] button on the micro-phone to transmit a 1750 Hz Burst Tone for repeater access.

If you own a non-European version of the FT-90R, but plan on visiting a countrywhich requires a 1750 Hz tone for repeater access, you may use MENU #26 to setup the ACC key for 1750 Hz Tone operation. See page 57 for details.


Operation

DTMF Tone GenerationThe white keys (with numbers, letters, or the Û/# characters printed on them) onthe microphone may be used for manual sending of DTMF tones for autopatch orrepeater control use. Just press the PTT switch, and hold it in, while pressing thedesired keys.

DTMF Autodialer OperationEight DTMF Autodialer memories are available on the FT-90R. These DTMFAutodialer memories can store up to 16 digits of a telephone number for repeaterautopatch or other use.

To load DTMF Autodialer memories, use following procedure:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “1 7 D T M F w .”2. Press the key, as needed, to select the DTMF Autodialer memory chan-

nel number into which you wish store a telephone number (“1 ” to “8 ”).3. Press the key momentarily..4. Press the or key to select the first digit of the telephone num-

ber you wish to store.5. When you have selected the correct digit, press the key momentarily..6. Now press the or key to select the second of 16 available

digits in the current DTMF Autodialer memory. Press the key (mo-mentarily).

7. Repeat this procedure for each digit in the telephone number.8. When entry of all digits is complete, press and hold in the key for one

second. This locks the DTMF string into the current register. You may nowpress the key momentarily to review your entry for accuracy..

9. Press the key to select another DTMF Autodialer memory channel,and repeat the process described above, beginning in step 2. When you aredone programming all desired DTMF Autodialer memory channels, press andhold in the key for 1.5 second to exit to normal operation.

To transmit the memorized telephone humber, use the following procedure:1. With the transceiver set to MENU #17 (“D T M F w ”), press the key, as

needed, to select the DTMF Autodialer memory channel you wish to send.If you can’t remember what number is stored in a particular memory, just press

momentarily to review the memory’s contents.2. Press and hold in the PTT key, then press the key momentarily while

holding in the PTT key. The DTMF string will be transmitted automatically.

Once you have pressed the button in this step, you can release thePTT switch, as the Autodialer transmits the entire DTMF string automatically.


Operation

The speed at which the DTMF digits are sent can be changed. Two speed levelsare available: Low (10 digits per second) and High (20 digits per second, thedefault setting).

To toggle between Low and High speed, use the following procedure:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “1 6 D T M F s .”

2. Press the key to select the desired speed: “5 0 m s ” (High speed) or“1 0 0 m s ” (Low speed).


You can also set a longer delay between the time the key is pressedand the first DTMF digit is sent. To set the delay time, use the followingprocedure:


knob to select “1 5 D T M F d .”

2. Press either the or key to select the desired speed from theavailable choices (5 0 /2 5 0 /4 5 0 /7 5 0 /1 0 0 0 ms).


MIC Gain ControlYou can reduce the microphone input level when operating on tightly-clusteredfrequencies (channel spacing of 12.5- or 15-kHz). This will reduce the transmitterdeviation, thus minimizing interference to other users.

To reduce the microphone input level:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “3 6 T x N a r .”

2. Press the key to change the display to “O N .”


To restore the microphone input level to the normal setting, select “O F F ” in step 2above.


Note


The FT-90R includes a versatile Memory system which makes everyday opera-tion more efficient. The Memory System provides 180 “standard” memories, plustwo pairs of band-limiting memories, and a one-touch “HOME” channel for eachband.

For ease in recognition of a channel’s function, Alpha-Numeric labels can be ap-pended to the frequency information.

The discussion below presumes that the function of the microphone’s [VFO/MR]button is set to the default “V F O /M R ” configuration. If you have used any of MENU

items 22~26 to assign the “V F O /M R ” function to another microphone button orfront panel key, use whatever key you have assigned for the “V F O /M R ” functionwhen the [VFO/MR] button is called for in the sections to follow. See page 47 fordetails on programming the microphone buttons and front panel keys.

Memory StorageTo store a frequency into memory:1. In the VFO mode, select the desired frequency, repeater shift, CTCSS tone, TX

power level, and, if this is a packet channel, the desired baud rate (1200/9600).2. Press and hold in the [VFO/MR] button on the microphone for one second. The

display will blink; if a frequency is displayed along with a blinking channelnumber, this will indicate that the channel already has frequency data stored on it.

3. Within five seconds of pressing the [VFO/MR] button, use the MAIN DIAL knobor the microphone’s [UP]/[DWN] buttons to select the desired memory channelfor storage. Look for a channel where no data is currently stored, so as not toover- write channel data you may wish to use.

4. Press the [VFO/MR] button again, this time momentarily, to store the displayeddata into the selected memory channel slot. The memory label will stop blink-ing for a second, then will disappear (since you are still operating in the VFOmode).

Recalling MemoriesFrom the VFO mode, momentarily press the [VFO/MR] button on the micro-phone to activate the “Memory” mode.

When more than one memory has been stored, use the MAIN DIAL knob to select amemory for operation. Alternatively, microphone’s [UP] or [DWN] button may beused to stop or scan through the available memories. When using the microphone’sbuttons, press and release the button to move one step up or down; press and holdthe [UP] or [DWN] button for one second to begin memory scanning.

Memory System Operation


DIRECT KEYPAD MEMORY RECALL (requires MH-36A6J)Which begins with “The desired memory channel may be recalled directly fromthe microphone’s keypad”.

To recall a memory channel from the keypad, just press the digits on the keypad inthe proper sequence, followed by the key..

Examples:To recall memory channel #5, press à .To recall memory channel #100, press à à à .

HOME Channel MemoriesConvenient one-touch “HOME” channel memories (one per band) are available tosimplify return to your most-often-used frequency. These memories do not ap-pear in the regular memory banks, to simplify operation.

The use of the HOME channel requires that one of the “Programmable” keys mustbe changed, via the MENU system, for a different function than that assigned at thefactory. See page 47 for details. The discussion below will assume that this func-tion has been assigned to the [P2] key on the microphone.

To recall the HOME channel on the current band, momentarily press the [P2] key (orwhichever “Programming key” you may have assigned to the “HOME” channel).The “H ” icon will appear at the bottom left corner of the display (while in the“CONTROL MODE” of the display). Another press of the [P2] key will recall theHOME channel of the other band. Press [VFO/MR] to revert to VFO or Memoryoperation.

Programming the HOME Channel(s)The factory default frequencies for the HOME channels are 146.520 MHz (EuropeVersion: 145.000 MHz) for VHF and 446.000 MHz (Europe Version: d 433.000MHz) for UHF. You can re-program the HOME channels in a manner identical tothat used for the regular memories.

1. From the VFO mode, tune in the frequency you wish to store, and set all re-peater shifts and other data just the way you do for “normal” memory channelstorage.

2. Press and hold in the [VFO/MR] button on the microphone for one second, thenpress the [P2] key momentarily.

Note that there is only one HOME channel for each band.



Naming and Displaying MemoriesYou can append to stored memories an Alpha/Numeric tag (up to seven charac-ters), to provide an easy reminder as to a particular frequency’s function.

To name a memory:1. Recall the memory to be named.


knob to select “0 2 A L P H c .”3. You will notice the first entry position blinking. While it is blinking, press the

key or key to select the first character of the memory’s name,then press the key to move on to the next character to the right.

4. Press the key or key to select thenext character, then press the

key to move on to the next character’s slot.5. Repeat steps 3 and 4, as necessary, to complete a name tag for your memory,

then press and hold the key for 1.5 second to save the Alpha/Numericname and exit to normal operation.

To turn on the memory name display:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “0 1 A L P H .”

2. Press the key to change the display to “O N .”3. Press and hold in the key for 1.5 second so that the name just assigned

(not the frequency) appears on the LCD.

To restore the frequency display, and hide the Alpha/Numeric label, select “O F F ”in step 2 above. Each memory channel may have its Alpha/Numeric On/Off statusset independently.

Loading a Memory into the VFOYou can easily select a memory and use that frequency as a starting point for VFOoperation.

1. Recall the memory channel of the frequency you wish to copy to the VFO.2. Press and hold in the MAIN DIAL knob for one second. The radio will switch to

the VFO mode, and it will be operating on the frequency of the memory channelyou just left. You may now tune freely without having affected the originalmemory contents.

Note that the previous VFO frequency will be overwritten by this action.




Memory-Only ModeOnce memory channel programming has been completed, you may place the radioin a “Memory Only” mode, whereby VFO operation is impossible. This may beparticularly useful during public-service events where a number of operators maybe using the radio for first time, and ultimate simplicity of channel selection isdesired.

To place the radio into the Memory Only mode, turn it off. Now press and hold inthe [VFO/MR] button on the microphone (or whichever key you have assigned forthe V F O /M R function) while turning the radio on.

To return to normal operation, repeat the above power-on procedure.

Erasing MemoriesWith 186 total memories available, there frequently are situations where you maydesire to “erase” memories which are no longer needed.

To erase a memory:1. Recall the memory to be erased. Note that Memory Channel 1 may not be

deleted, as it is the Priority Channel.2. Press and hold the [VFO/MR] button on the microphone for one second.3. Press the button. This will cause the display to shift to Memory

Channel “1,” and the previously-selected memory will now be eliminated fromthe memory bank.

Important Note:Erased memory channels can not be recovered.


Scanning Features

Scanning OperationThe FT-90R’s microprocessor-based scanning feature allows quick scanning ofthe memory channels, or sweeping of a band, looking for activity.

Before activating the scanner, make sure that the SQL control is set to silence thebackground noise when no signal is present. If the noise is not squelched, thetransceiver will “think” that it has found a signal, and will not scan.

Scanning may be started or stopped with the microphone’s [UP] or [DWN] button.

The following techniques are used for scanning:1. Pressing and holding in either the [UP] or [DWN] button for one second in the

VFO mode will cause upward or downward band scanning, respectively, tobegin.

2. Pressing and holding in either the [UP] or [DWN] button for one second in theMemory mode will cause memory channel scanning toward a higher- or lower-numbered memory channel, respectively.

3. Scanning pauses when a signal opens the squelch, and the decimal point on thedisplay will blink. You can choose one of two scan-resume modes (describedbelow).

4. To halt the scan manually, the easiest way is to push the PTT switch on themicrophone momentarily (no transmission will occur while you are scanning).The scan may also be halted manually by pressing the microphone’s [UP] or[DWN] button, or the microphone’s [VFO/MR] button.

Scan-Resume OptionsTwo scan-resume modes are available on the radio:• In the B U S Y mode, the scanner will remain stopped for as long as there is

carrier present on the channel; after the carrier drops at the end of the otherstation’s transmission, the scanner will resume.

• In the T I M E mode, the scanner will halt for five seconds only, after whichscanning will resume (whether or not the other station is still transmission).

To change the scan-resume mode, use the following procedure:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “2 9 S C A N .”

2. Press the key to select the desired scan-resume mode (B U S Y or T I M E ).



Scanning Features

Memory Skip ScanningWhen you have some continuously-active channels in memories, you may wish toskip them for scanning, but still have them available for manual selection.

To mark a memory to be skipped during scanning, use the following procedure:1. Recall the memory channel to be skipped. Note that Memory Channel 1 may

not be skipped.2. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “3 1 S K I P .”

3. Press the key to select “S K I P .”


To re-enable a “skipped” memory channel, select “S T O P ” in step 3 above.

Temporary Memory SkipIf the scanner repeatedly stops on a channel due to temporary noise or interfer-ence, you can temporarily mark it to be skipped (except the Memory Channel 1).The channel will be skipped until you manually stop the scan (by pressing thePTT switch, for example).

To skip a channel temporarily, press the key momentarily while the scan-ner has stopped on the channel to be skipped. The scanner will instantaneouslyresume, and that channel will not be scanned during this scanning session.

Programmable Band-Scan LimitsBesides band and memory scanning, this transceiver can be set to tune or scanonly the frequencies between user-defined lower and upper limits. For example,during 2-meter band scanning you may wish to limit tuning/scanning to 144.5 ~148 MHz, to avoid encroachment on the SSB/CW sub-band between 144.0 and144.5 MHz.

These limits are stored in special “Sub-Band Limit Memories” labeled P M S - 1 L ,P M S - 1 U , P M S - 2 L , and P M S - 2 U , with “L” and “U ” designations representing theLower and Upper limits, respectively.

To utilize this feature, use the following steps:1. Store the lower edge of the desired scanning/tuning range in memory “P M S -

1 L ,” and the upper edge in memory “P M S - 1 U ” (or, alternatively, in memories“P M S - 2 L” and “P M S - 2 U ”).

2. With any of these memories recalled, press the MAIN DIAL knob momentarily to


activate the Programmable Band-Scan Limits. The frequencies stored inmemories “L ” and “U ” will now serve as tuning and scanning limits, thuscreating a tuning sub-band. The “p ” icon will appear in the bottom left cornerof the display in the “CONTROL MODE” of the display.

To cancel the sub-band limits and return to normal memory operation, press the[VFO/MR] button on the microphone momentarily. If you are scanning, or if youwant to switch to VFO operation, press the [VFO/MR] button twice from the“limited sub-band” mode of operation.

Once you have stored the “L ” and “U ” memories, you can re-activate the sub-bandlimits by simply recalling either memory and pressing the MAIN DIAL knob. How-ever, you cannot activate the sub-band limits when either of these memories ismarked to be skipped during scanning.

If you have stored sub-band limits in both the P M S - 1 L /1 U and P M S - 2 L /2 Umemory registers, the scanning behaves somewhat differently: the transceiver willscan from the “P M S - 1 L ” frequency to the “P M S - 1 U ” frequency, then jump tothe “P M S - 2 L ” frequency and scan to the “P M S - 2 U ” frequency, after which itwill return to the “P M S - 1 L” frequency and repeat the process. If you want tohave something stored in the “P M S - 2 L” and “P M S - 2 U ” registers, but do notwish to include them in the scanning process, just mark them to be “Skipped” asdescribed previously.

Smart Search OperationThe Smart Search feature may be used to load – automatically with no operatorintervention – a special bank of up to 50 memory channels (per band) based onactivity. Smart Search will sweep either the entire band or the portion of the bandwithin the Programmable Band-Scan Limits and will load the Smart Search memorybank with the frequency data pertaining to those channels on which activity isfound. The channels are loaded in the order in which they are encountered, notaccording to signal strength or by ascending frequency.

The Smart Search feature is especially useful when visiting a city for the first time,where you may be unfamiliar with the repeater frequencies; Smart Search discov-ers where the local activity is to be found, and automatically loads those frequen-cies for you.

Smart Search operation is simple to activate:1. Press and hold in the key for one second.2. The Smart Search process will now cause the radio to scan upward on current

band, loading channels on which it encounters a signal strong enough to openthe squelch.

Scanning Features


Scanning Features

3. When 50 channels are loaded or the scanner reaches the band edge, the scannerwill stop and the transceiver will revert to the starting frequency.

4. To recall the Smart Search Memories just stored, rotate the MAIN DIAL knob.5. Press the microphone’s [VFO/MR] button momentarily to exit the Smart Search

mode.

Note that these memories are so-called “soft” memories; they will be lost if youexit Smart Search to a VFO/Memory, or if you initiate a new Smart Search. SmartSearch also does not store CTCSS or DCS information; if you cannot access arepeater found during Smart Search, you may need to investigate possible accesstones.

Priority Channel MonitoringIn the U.S.A. version, the Priority function allows automatic checking for activityon Memory Channel 1 every five seconds while operating on the VFO or a differ-ent memory. When the receiver detects a signal on the designated “Priority” memory(Channel 1), operation automatically shifts to that memory while the signal ispresent (plus a few seconds). If you transmit while “paused” on the Priority chan-nel, priority monitoring will cease, and the transceiver will “hold” indefinitely onthe Priority channel.

The transceiver will only check Memory Channel 1 as the Priority channel if youare operating in the memory mode. No other memory may be designated as thePriority channel.

To set up for Priority monitoring:1. Preset the SQL control to silence the background noise on a clear channel, then

store the frequency to be the “Priority” channel into Memory Channel 1.2. Press the [VFO/MR] button on the microphone to operate in the VFO mode. If

you are in the memory mode, select the memory on which you wish to operate(other than the Priority channel).

3. Press the microphone’s [ACC] button momentarily to start Priority monitoring(a “P ” icon will appear at the bottom left-hand corner on the LCD in the “CON-TROL MODE” of the display).

During Priority monitoring, the displayed frequency will shift to the Priority memorybriefly about every five seconds, while the receiver checks for the presence of asignal.

When no signal appears on the Priority memory (causing the squelch to open),you can tune, transmit and receive on the VFO, or select and operate on othermemories; however, you cannot scan (except manually, using the microphone’s


[UP] and [DWN] buttons), as the scanning logic circuits are already dedicated tothe priority scanning activities.

If a station you wish to talk with appears on the Priority memory, press the PTTswitch momentarily while receiving their signal (no transmission will occur) tohalt Priority scanning. Otherwise, when a signal appears on the Priority channel,Priority monitoring will just pause on that channel, and the decimal on the displaywill blink. Priority monitoring will resume based on the setting of the regularscanning-resume mode - either after a 5-second pause, or after the carrier drops out.

To cancel Priority monitoring, press the microphone’s [ACC] or [VFO/MR] but-ton momentarily.

A few other rules govern priority operation:m You can not scan operation during priority operation.

m The priority function is not disabled by switching the transceiver off. If youwere engaged in priority monitoring at the moment you turned the radio off,it will assume that you will want to continue priority monitoring during yournext operating session, and will come up still in the priority mode when thetransceiver is switched back on.

Priority monitoring is also available in the European version, although none of the“Programmable” keys is set up for Priority monitoring as a default setting. Thefunction of one of these keys may easily be set up for Priority monitoring; see the“Programming the Front Panel/Microphone Key Functions” section on page 47for details.

Scanning Features


ARTS: Auto Range Transpond System

This system uses DCS signaling to inform you when you and another ARTS-equipped station are within communications range. Both stations must first selectDCS operation using the same DCS code.

Whenever you press the PTT, or every 30 seconds after ARTS is activated, yourradio will transmit a (subaudible) DCS signal. If the other radio is in range, thebeeper (if enabled) will sound and “A R T S I N ” will appear on the display. Whetheryou talk or not, the radios will continue to poll each other every 30 seconds whileARTS is activated.

You can also have your radio transmit your callsign via CW every nine minutes, tocomply with identification requirements.

If you move out range for more than one minute (two polls), your radio will sensethat no signal has been received. A beep will sound, and the display will change to“A R T S O U T ” (out of range). If you move back into range, your radio will againbeep, and the display will change back to “A R T S I N .”

During ARTS operation, the microprocessor makes it impossible to change theoperating frequency or other settings; you must first terminate ARTS to resumenormal operation. This is a safety feature to prevent accidental loss of contact dueto channel change, etc.

Here is how to activate ARTS:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “0 5 A R T S .”

2. Press the key to select the ARTS operating mode: “R X ” (receive-only),“T X ” (transmit-only), “T R X ” (transceive), or “O F F ” The operating descriptionsassume that both radios are set to “T R X .”

3. Press and hold in the key for 1.5 second to save the entry and exit. Thedisplay will now show “A R T S O U T . ” After two pollings (one minute), if a re-sponse is not detected, “A R T S O U T ” will appear continuously; otherwise “A R T SIN ” will be displayed as long as both stations remain in range.

4. To cancel ARTS operation, select “O F F ” in step 2 above.


ARTS ModesIn the previous ARTS description, both transceivers were set to the “T R X ”(transceive) mode. There are two other ARTS modes available via the MENU sys-tem, as outlined below:

R X Use this mode if you only want your radio to listen, and not poll the otherstation (in which case their radio should be set to the “TX” mode). Here, yourradio will beep and display “A R T S I N ” or “A R T S O U T ” to indicate the stateof connection.

T X Likewise, this puts your radio into a transmit-only “beacon” mode where youwon’t hear the polling beeps (but you can still hear when the other stationtalks). When activated, you have no display of whether or not the other sta-tion is in range (“A R T S I N ” and “A R T S O U T ” do not appear). You shouldhave your CW IDer enabled when this mode is activated.

CW ID (Morse Identifier) Set upThe ARTS feature includes a CW identifier, as mentioned previously. The radiocan be instructed to send “DE (your callsign) K” in Morse code every nine min-utes during ARTS operation. The callsign may contain up to 7 characters.

Here’s how to program the CW Ider:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “0 8 C W I D # .”2. You will notice the first character’s entry slot blinking. While it is blinking,

press the or key to select the desired character, then press the key to move on to the next character to the right.

3. Press the or key to select the next number or letter, then press

the key to move on the next character..

4. When the callsign is complete, press and hold in the key for 1.5 secondto save the CW ID entry and exit to normal operation.

To activate the CW Ider for use during ARTS operation:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “0 7 C W I D .”

2. Press the key to change the display to “O N .”


To disable the CW IDer, select “O F F ” in step 2 above.

ARTS: Auto Range Transpond System


Packet Operation

Packet operation generally requires only that you connect your TNC per the illus-tration on page 16, then configure the channel for 1200 bps or 9600 bps using theMENU.

To select the Packet baud rate, use the following procedure:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “2 1 P C K T .”

2. Press the key to select the desired baud rate (1 2 0 0 b p s or 9 6 0 0 b p s ).


The packet baud rate selection can be set independently for each band (VHF andUHF) during VFO operation. Note also that the packet baud rate may be storedinto memory channels, so you won’t need to enter the MENU each time you wish tooperate in the Packet mode.


Miscellaneous Settings

Time-Out TimerThe “Time-Out Timer” (TOT) feature is designed to force the transceiver into the“receive” mode after a pre-set time period of continuous transmission (the defaultis 6 minutes). This feature prevents your transceiver from transmitting a “deadcarrier” for a long period of time in the event that the microphone PTT switch isaccidentally locked in the “TX” condition.

The Time-Out Timer’s “switch-to-receive” time may be adjusted, in one minuteincrements, for any period between 1 and 60 minutes.

To change the default (6 minute) time setting:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “3 5 T O T .”

2. Press either the or key to select the desired time interval (be-tween 1 and 6 0 minutes, or O F F ).


Automatic Power-OffThe “Automatic Power-Off” (APO) feature will turn the radio completely off aftera user-defined period of PTT or key/button inactivity. If you do not press anyfront panel keys or buttons, do not rotate the MAIN DIAL knob, do not use themicrophone’s keys and buttons, do not transmit, and so long as the transceiver isnot scanning or engaged in priority monitoring, the radio will shut itself off afterthe specified time period. This feature is useful in minimizing battery drain in amobile installation if you forget to turn the transceiver off when you leave yourvehicle.

To activate the APO feature:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “0 3 A P O .”

2. Press either the or key to select the desired “switch-off” time(between 1 and 1 2 hours, or O F F ).



Cooling Fan ControlThe FT-90R’s microprocessor will automatically activate the cooling fan duringtransmitting and for thirty seconds thereafter, or when the chassis temperaturerises.

You can change the operating mode of the cooling system, should the ambi-ent temperature in your station require it, using the following procedure:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to select “1 8 F A N .”

2. Press the key to change the desired operating mode.

A U T O : The cooling fan rotates at high speed when the chassis tempera-ture rises; the fan rotates at low speed otherwise.

T X : The cooling fan rotates high speed when transmitting, and for 30seconds thereafter; the fan rotates at low speed otherwise.

A U T O /TX : The cooling fan rotates at high speed when both of the above con-ditions exist; the fan rotates at low speed otherwise.

OFF: The cooling fan rotates continuously at low speed.


Programming the Front Panel/Microphone Key FunctionsDefault FT-90R key functions have been assigned (at the factory) to the front

panel’s and keys, as well as the microphone’s s [P1], [P2], and[ACC] buttons. These may be changed by the user, if you wish to define anotherfunction for a particular key or keys.

To change the assignment of a key’s function:1. Press and hold in the key for one second, then rotate the MAIN DIAL

knob to the Menu Item # corresponding to the key to be assigned a function(2 2 P g : ß, 2 3 P g : à, 2 4 P g : P 1 , 2 5 P g : P 2 , or 2 6 P g : A C ).

2. Press the key to select the function you wish to assign to the key orbutton you selected in the previous step. The available choices are:

H O M E C H Switches frequency to the HOME channel.

VFO /MR Switches frequency control between VFO and Memory.

TONE Selects CTCSS or DCS mode and tone/code.

PRI Activates Priority Channel monitoring.



S C A N U P Activates Scanning toward higher frequency/memory channel.

S C A N D N Activates Scanning toward lower frequency/memory channel.

R P T R Selects Repeater Shift direction.

REVERSE Reverses Repeater Uplink/Downlink frequencies.

T . B U R S T Activates 1750 Hz Tone Burst.

T X P W R Allows setting of the transmitter power level.

3. Rotate the MAIN DIAL knob to select another programmable key or button tomodify, if desired, and make your selection from the above list.


Note:The function of the [VFO/MR] key is fixed on the [VFO/MR] selection.

DCS Code InversionThe DCS system was first introduced in the commercial LMR (Land Mobile Ra-dio) service, where it is now in widespread use.

DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at adata rate of 134.4 bps (bit/sec). Occasionally, signal inversion can result in thecomplement of a code being sent or received. This prevents the receiver squelchfrom opening with DCS enabled, as the decoded bit sequence would not matchthat selected for operation.

Typical situations that might cause inversion to occur are:

m Connection of an external receiver preamplifier.

m Operating through a repeater.

m Connection of an external linear amplifier.

Note that code inversion does not mean that any of the above listed equipment isdefective! In certain amplifier configurations, the output signal (phase) is invertedfrom the input. Small signal or power amplifiers having an odd number (1, 3, 5,etc.) of amplification stages may result in inversion of a transmitted or receivedDCS code.




While under most circumstances this should not occur (amplifier designs andindustry standards take this into account), if you find that your receiver squelchdoes not open when both you and the other station are using a common DCS code,you or the other station (but not both) can try the following:


knob to select “1 4 D C S n r .”

2. Press the key to select one of the following modes:

T R X N O R : Encoder : Normal Decoder ; Normal

RX REV : Encoder : Normal Decoder ; Reverse (Inverted)

TX REV : Encoder : Reverse (Inverted) Decoder ; Normal

TRX REV : Encoder : Reverse (Inverted) Decoder ; Reverse (Inverted)


Remember to restore the default setting to “T R X N O R ” (Encoder Normal; De-coder Normal) when done.

Demonstration ModeWhen the FT-90R is first turned on, the supplied DC voltage is displayed belowthe field which shows the operating frequency. The FT-90R also provides analternative opening display option, called the “Demonstration” mode. This is atwo-line scrolling message which might, for example feature your callsign on thetop line and your name on the next line.

If your transceiver currently displays the DC voltage below the frequency, you can

activate the Demonstration mode by pressing and holding in the buttonwhile turning the transceiver on. The display will then indicate the demonstrationcomments until you activate some function on the radio (rotate the MAIN DIAL

knob, etc.)

Press and hold in the button return, while turning the FT-90R on, toreturn to the normal opening display.



Programming the Demo MessageYou also can change the Demonstration mode message, if desired, using thefollowing procedure:1. Press and hold in the key while turning the transceiver on; you will

notice the first character of the upper message area blinking.2. While this character is blinking, rotate the MAIN DIAL knob to select the first

character of the top message, then press the key to move on to the nextcharacter to the right.

3. Rotate the MAIN DIAL knob to select the next character, then press the key to move on to the next character’s entry location.

4. Repeat steps 2 and 3, as necessary, to complete the upper message (up to 50characters).

5. Now press the key momentarily; you will now observe the first charac-ter of the lower message area blinking.

6. Repeat steps 2 and 3 again to set the lower message (up to 50 characters).

7. Press the key to save the new messages and exit.

Resetting the CPUIf you encounter erratic operating results, or wish to clear all transceiver settingsso as to start with the factory defaults, resetting the microprocessor provides aquick method of “starting over” with original factory settings.

m To reset all MENU settings to their factory defaults, press and hold in the key and the button while turning the transceiver on. This

procedure does not alter or erase any channel memories you may have stored.

m To perform a CPU master reset for all memories and MENU settings, pressand hold in the key, the key, and the button whileturning the transceiver on.


Transceiver Cloning

You can transfer all data stored in one FT-90R to another FT-90R by utilizing thehandy “Cloning” feature. This requires a user-constructed Cloning cable whichconnects the MIC jacks on the two transceivers, as shown below.

To clone from one transceiver to another, use the following procedure:1. Insert the Clone Cable into the MIC jack of each transceiver.2. Turn both transceivers off, then press and hold in the microphone’s [ACC]

button (on each radio) while turning the power on again. The “C L O N E ” indica-tion will appear on the display.

3. On the “destination” radio, press the button. The “R ” indicator will ap-pear at the bottom left corner on the display (in the Frequency Control displaymode).

4. Now, on the “source” radio, press the key. The “T ” indicator will ap-pear in the bottom left corner on the display, and the cloning data transfer willimmediately begin.

5. If there is a problem during the cloning process, “E r r o r” will be displayed.Check your cable connections, and try again.

6. If cloning was successful, turn the “destination” radio off. Now turn the “source”radio off.

7. Remove the Clone Cable. Channel and operating data for both radios are nowidentical. They both may be turned on now for normal operation.


The FT-90R’s MENU system allows a number of transceiver operating parametersto be custom-configured for your operating requirements.

The MENU is easy to activate and set, using the following procedure:

1. Press and hold in the key for one second.2. Rotate the MAIN DIAL knob to select the MENU item to be adjusted.

3. Press the or key, as instructed in the sections to follow, toadjust the status or value of the MENU item. In many cases, the LCD field just

above the key will show a “q” icon, indicating that the key below it isthe one which should be pressed to toggle the available selections.

4. After completing your adjustment, press and hold in the key for 1.5second to save the new setting and exit to normal operation.

MENU items are conveniently arranged in alphabetical order.
