    INTRODUCTION

    The FT-7800R is a ruggedly-built, high quality Dual Band FM transceiver providing 50
    Watts of power output on the 144 MHz Amateur band and 40 Watts on the 430 MHz Amateur band.
    The high power output of the FT-7800R is produced by its RD70HVF1 Power MOS FET
    amplifier, with a direct-flow heat sink and thermostatically-controlled cooling fan maintaining a safe temperature for the transceiver’s circuitry.
    Featuring 1055 memory channels which enable the storage of Independent Transmit Frequencies (“Odd Split”), and built-in CTCSS and DCS encoder/decoder circuits, the
    FT-7800R includes also provision for remote-head mounting, utilizing the optional
    YSK-7800 Separation Kit, which allows installation even in the most compact of cars.
    Additional features include a convenient access key for Vertex Standard’s WIRES™ (WideCoverage Internet Repeater Enhancement System), a transmit Time-Out Timer (TOT), Automatic Power-Off (APO), Automatic Repeater Shift (ARS), plus Yaesu’s exclusive ARTS™
    (Auto-Range Transponder System) which “beeps” the user when you move out of communications range with another ARTSTM equipped station. And an RF squelch circuit allows the
    owner to set the squelch to open at a programmable setting of the S-Meter, thus reducing
    guesswork in setting the squelch threshold.
    We recommend that you read this manual in its entirety, so as to understand fully the many
    features of your new FT-7800R transceiver.

    INSTALLATION
    This chapter describes the installation procedure for integrating the FT-7800R into a typical amateur radio station. It is presumed that you possess technical knowledge and conceptual understanding consistent with your status as a licensed radio amateur. Please take some
    extra time to make certain that the important safety and technical requirements detailed in
    this chapter are followed closely.

    PRELIMINARY INSPECTION
    Inspect the transceiver visually immediately upon opening the packing carton. Confirm that
    all controls and switches work freely, and inspect the cabinet for any damage. Gently shake
    the transceiver to verify that no internal components have been shaken loose due to rough
    handling during shipping.
    If any evidence of damage is discovered, document it thoroughly and contact the shipping
    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 or other evidence of damage incurred
    during shipping; if it is necessary to return the unit for service or replacement, use the original packing materials but put the entire package inside another packing carton, so as to
    preserve the evidence of shipping damage for insurance purposes.

    INSTALLATION TIPS
    To ensure long life of the components, be certain to provide adequate ventilation around the
    cabinet of the FT-7800R.
    Do not install the transceiver on top of another heat-generating device (such as a power
    supply or amplifier), and do not place equipment, books, or papers on top of the FT-7800R.
    Avoid heating vents and window locations that could expose the transceiver to excessive
    direct sunlight, especially in hot climates. The FT-7800R should not be used in an environment where the ambient temperature exceeds +140 °F (+60 °C).

    INSTALLATION
    SAFETY INFORMATION
    The FT-7800R is an electrical apparatus, as well as a generator of RF (Radio Frequency)
    energy, and you should exercise all safety precautions as are appropriate for this type of
    device. These safety tips apply to any device installed in a well-designed amateur radio
    station.
    Never allow unsupervised children to play in the vicinity of your transceiver or antenna installation.
    Be certain to wrap any wire or cable splices thoroughly with insulating electrical
    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 to each other.
    Do not stand in front of a directional antenna while you are transmitting into that
    antenna. Do not install a directional antenna in any location where humans or pets
    may be walking in the main directional lobe of the antenna’s radiation pattern.
    In mobile installations, it is preferable to mount your antenna on top of the roof of the
    vehicle, if feasible, so as to utilize the car body as a counterpoise for the antenna and
    raise the radiation pattern as far away from passengers as possible.
    During vehicular operation when stopped (in a parking lot, for example), make it a
    practice to switch to Low power if there are people walking nearby.
    Never wear dual-earmuff headphones while driving a vehicle.
    Do not attempt to drive your vehicle while making a telephone call on an autopatch
    using the DTMF microphone. Pull over to the side of the road, whether dialing manually or using the auto-dial feature.

    INSTALLATION
    ANTENNA CONSIDERATIONS
    The FT-7800R is designed for use with antennas presenting an impedance of near 50 Ohms
    at all operating frequencies. The antenna (or a 50 Ohm dummy load) should be connected
    whenever the transceiver is turned on, to avoid damage that could otherwise 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 transceivers, may not be
    capable of withstanding this power level. Consult the antenna manufacturer’s specification
    sheet for details.
    Most all FM work is performed using vertical polarization. When installing a directional
    antenna such as a Yagi or Cubical Quad, be certain to orient it so as to produce vertical
    polarization, unless you are engaged in a special operating situation where horizontal polarization is used. In the case of a Yagi antenna, orient the elements vertically for vertical
    polarization; for a Cubical Quad, the feedpoint should be at the center of one of the vertical
    sides of the driven element (or at a side corner, in the case of a diamond-shaped Cubical
    Quad).
    Note that this transceiver is designed with wide frequency coverage in the VHF/UHF spectrum. For general listening, you may wish to have a broadband antenna such as a discone
    available, as a directional antenna such as a Yagi will have degraded performance outside
    the Amateur band for which it is designed.
    Excellent reference texts and computer software are available for the design and optimization of VHF and UHF antennas. Your dealer should be able to assist you with all aspects of
    your antenna installation requirements.
    Use high-quality 50 Ohm coaxial cable for the lead-in to your FT-7800R 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 increases, so an 8-meter-long
    (25’) coaxial line with under 1 dB of loss at 144 MHz may have a loss of 3 dB or more at 446
    MHz; choose your coaxial cable carefully based on the installation location (mobile vs.
    base) and the overall length of the cable required (for very short runs of cable in a mobile
    installation, the smaller, more flexible cable types may be acceptable).

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

    In outdoor installations, be certain to weatherproof all connectors thoroughly, as water entering a coaxial cable will cause losses to escalate rapidly, thus diminishing your communications effectiveness. The use of the shortest possible length of the highest quality coaxial
    cable that fits within your budget will ensure the best performance from your FT-7800R.

    INSTALLATION
    MOBILE INSTALLATION
    The FT-7800R must only be installed in vehicles having a 13.8 Volt negative ground electrical system. Mount the transceiver where the display, controls, and microphone are easily
    accessible, using the supplied MMB-36 mounting bracket.
    The transceiver may be installed in almost any location, but should not be positioned near a
    heating vent nor anywhere where it might interfere with driving (either visually or mechanically). Make sure to provide plenty of space on all sides of the transceiver so that air can
    flow freely around the radio’s case. Refer to the diagrams showing proper installation procedures.

    INSTALLATION
    MOBILE INSTALLATION
    Mobile Power Connections
    To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the supplied DC
    power cable directly to the battery terminals. Do not attempt to defeat or bypass the DC
    cable’s fuse - it is there to protect you, your transceiver, and your vehicle’s electrical system.
    Warning!
    Never apply AC power to the power cable of the FT-7800R, nor DC voltage greater
    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 Limited Warranty on this product.
    Before connecting the transceiver, check the voltage at the battery terminals while revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regulator
    before proceeding with installation.
    Connect the RED power cable lead to the POSITIVE (+) battery terminal, and the BLACK
    power cable lead to the NEGATIVE (–) terminal. If you need to extend the power cable,
    use #12 AWG or larger insulated, stranded copper wire. Solder the splice connections
    carefully, and wrap the connections thoroughly with insulating electrical tape.
    Before connecting the cable to the transceiver, verify the voltage and polarity of the
    voltage at the transceiver end of the DC cable using a DC voltmeter. Now connect the
    transceiver to the DC cable.

    INSTALLATION
    BASE STATION INSTALLATION
    The FT-7800R is ideal for base station use as well as in mobile installations. The
    FT-7800R is specifically designed to integrate into your station easily, using the information to follow as a reference.

    AC Power Supplies
    Operation of the FT-7800R from an AC line requires a power source capable of providing
    at least 9 Amps continuously at 13.8 Volts DC. The FP-1023 and FP-1030A AC Power
    Supplies are available from your Yaesu dealer to satisfy these requirements. Other wellregulated 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 connections 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 NEGATIVE (–) power supply
    terminal.

    Packet Radio Terminal Node Controller (TNC)
    The FT-7800R provides a convenient rear-panel DATA jack for easy connections to your
    TNC. This connector is a standard mini-DIN connector. A pre-wired connector and cable
    assembly option, model CT-39A, is available from your local Yaesu dealer.
    The FT-7800R’s DATA jack connections are optimized for the data transmission and reception speed in use. In accordance with industry standards, the signal levels, impedances, and
    bandwidths are significantly different on 9600 bps as opposed to 1200 bps. If your TNC
    does not provide multiple lines to accommodate such optimization, you may still be able to
    utilize your TNC, if it is designed for multiple-radio use, by connecting the TNC “Radio 1”
    port to the 1200 bps lines on the FT-7800R, and the “Radio 2” port to the 9600 bps lines.
    The pin connections of the Data connector are shown below.

    BASE STATION INSTALLATION
    Note that 9600 bps packet transmit-deviation adjustment is very critical to successful operation, and can only be accomplished using a calibrated deviation meter (such as that found on
    an FM Service Monitor used in a communications service center). In most cases, the Packet
    Data Input level (set via a potentiometer inside the TNC) must be adjusted to provide a
    deviation of ±2.75 kHz (±0.25 kHz). Check with your packet node’s sysop if you have any
    questions about the appropriate deviation level for your network. Note also that high throughput on 9600 bps frequently requires strong signals, so you may wish to consider the use of a
    directional antenna such as a Yagi for communication with high-speed packet nodes.
    The setting of the 1200 bps Packet Data Input level is much less critical than it is at 9600 bps,
    and satisfactory adjustment to the optimum (±2.5 ~ ±3.5 kHz) deviation can usually be done
    “by ear” by adjusting the TNC’s 1200 bps TX Audio Level potentiometer so that the outgoing
    packets (as monitored on a separate VHF or UHF receiver) are approximately the same level
    as (A) the DTMF tones or (B) the 1750 Hz Burst tone produced using the microphone.
    Finally, note that the Menu (“Set”) mode allows you to set the Packet data rate (1200 or
    9600 bps) independently for each band. If you have trouble getting your FT-7800R to
    respond correctly during packet operation, check to be certain that you do not have Menu
    #26 (PKT.SPD) set to the wrong data rate.
    You may activate the microphone input while operating on the packet mode via the Menu
    #25 (PKT.MIC), if desired. Generally, we do not recommend this, as a “live” microphone’s
    audio input will tend to reduce throughput by interfering with the packets being transmitted
    by your radio.

    BASIC OPERATION
    Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features
    of the FT-7800R. 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!

    TURNING THE TRANSCEIVER ON AND OFF
    1. To turn the transceiver on, press and hold in the
    PWR ( ) switch for 1/2 second.
    When you turn on the FT-7800R, the current DC
    supply voltage is indicated on the LCD for 2 seconds. After this interval, the display will switch its
    normal indication of the operating frequency.
    2. To turn the transceiver off, again press and hold in
    the PWR ( ) switch for 1/2 second.

    ADJUSTING THE AUDIO VOLUME LEVEL AND SQUELCH SETTING
    At first, set the SQL knob fully counter-clockwise.
    Now, you may rotate the VOL knob clockwise to adjust the receiver volume for a comfortable listening
    level, using the background noise as a reference.
    To set the squelch, turn the SQL knob clockwise a
    slightly past the point where the background noise is
    muted. This is the point of best sensitivity to weak signals, and we recommend that you not rotate the SQL knob very much past the point where
    the background noise is just silenced.
    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 24 for details

    SELECTING THE OPERATING BAND
    Press the [BAND(SET)] key to move the operating
    band:
    144 MHz 250 MHz 350 MHz
    430 MHz 850 MHz 144 MHz ......
    You may select the operating band by pressing the microphone’s [P1] key.

    FT-7800R OPERATING MANUAL



  • Page 23

    BASIC OPERATION
    FREQUENCY NAVIGATION
    1) Tuning Dial
    Rotating the DIAL knob allows tuning in the pre-programmed steps established for the VFO
    frequency. Clockwise rotation of the DIAL knob causes the FT-7800R to be tuned toward a
    higher frequency, while counter-clockwise rotation will
    lower the operating frequency.
    Press the [MHz(PRI)] key momentarily, then rotate the
    DIAL knob, to change the frequency steps to 1 MHz
    per step. This feature is extremely useful for making
    rapid frequency excursions over the wide tuning range
    of the FT-7800R.

    2) Direct Keypad Frequency Entry (MH-48A6J Microphone)
    The keypad of the MH-48A6J DTMF Microphone may be used for direct entry of the operating frequency.
    To enter a frequency from the MH-48A6J keypad, just press the numbered digits in the
    proper sequence. There is no “Decimal point” key on the MH-48A6J keypad.
    Examples: To enter 146.480 MHz, press [1]
    To enter 433.000 MHz, press [4]

    [4]
    [3]

    [6]
    [3]

    [4]
    [0]

    [8]
    [0]

    [0]
    [0]

    3) Scanning
    From the VFO mode, press and hold in the [SCAN(SEL)] key for 1/2 second, then rotate the
    DIAL knob to select the bandwidth for the VFO scanner. Now, press the [SCAN(SEL)] key
    momentarily to initiate scanning toward a higher frequency. The FT-7800R will stop when it
    receives a signal strong enough to break through the squelch threshold. The FT-7800R will
    then hold on that frequency according to the setting of the “Resume” mode (Menu #37 (SCAN);
    see page 73). See page 41 for details regarding the VFO Scan operation.
    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 knob one click in the counter-clockwise direction
    while the FT-7800R is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
    Press the [SCAN(SEL)] key (or the PTT key) again to stop scanning.
    You may also initiate the scanner by pressing and holding in the microphone’s
    [UP] or [DWN] key. However, in this case, the scanner will sweep frequencies
    only on the current band. If you would like the scanner not to be restricted to the current
    band, you may change Menu #46 (VFO.BND) to allow the scanner to hop to the low edge
    of the next-highest band when the VFO frequency reaches the high end of the current
    band (or vice- versa). See page 75 for details.

    BASIC OPERATION
    TRANSMISSION
    To transmit, simply close the PTT (Push To Talk) switch
    on the microphone when the frequency is clear. Hold
    the microphone approximately 25 mm (1”) from your
    mouth, and speak into the microphone in a normal voice
    level. When your transmission is complete, release the
    PTT switch; the transceiver will revert to the receive
    mode.
    When the RF power amplifier heat sink rises to a factory preset temperature, the
    transmit power level will be reduced to the “LOW” setting automatically to prevent over-heating of the radio. If you leave transmit in this condition (even in the “LOW”
    mode) for an extended period of time, the radio will be forced to return to the receive
    mode.

    Changing the Transmitter Power Level
    You can select from among a total of four transmit power levels on your FT-7800R.
    To change the power level, press the [LOW(ACC)]
    key to select one of four power settings. These power
    levels will be stored, in memory registers, at the time
    of memory storage (see page 32 for details on Memory
    operation).
    During transmission, the Bar Graph will deflect in the
    display, according to the power output selected.

    “LOW” POWER (5 W)

    “MID 2” POWER (10 W)

    “MID 1” POWER (20 W)

    “HIGH” POWER (50 W: 144 MHZ, 40 W: 430 MHZ)

    ADVANCED OPERATION
    CHANNEL STEP SELECTION
    The FT-7800R’s synthesizer provides the option of utilizing channel steps of 5/10/12.5/15/
    20/25/50/100 kHz per step, as well as an automatic step selection based on the current
    operating frequency (“AUTO”), any number of which may be important to your operating
    requirements. The FT-7800R is set up at the factory in the “AUTO” configuration, which
    probably is satisfactory for most operation. However, if you need to change the channel step
    increments, the procedure to do so is very easy; remember to get set up on the desired band
    before making any changes, as different steps may be programmed for each operating band.

    RECEIVING MODE SELECTION
    The FT-7800R provides for automatic mode change when the radio is tuned to different
    operating frequencies. However, should an unusual receiving situation arise in which you
    need to change to other receiving mode, the procedure to do so is very easy.
    1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #35 (RX MOD).
    3. Press the [BAND(SET)] key momentarily, then rotate
    the DIAL knob to select the desired receiving mode.
    AUTO: Automatic mode setting per default values
    for the selected frequency range
    FM: Frequency Modulation (Narrow FM)
    AM: Amplitude Modulation
    4. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold in
    the [BAND(SET)] key for 1/2 second to exit to normal operation.
    Unless you have a compelling reason to do so, leave the Automatic Mode Selection feature on so as to save time and trouble when changing bands. If you make
    a mode change for a particular channel or station, you can always store that one channel
    into memory, as the mode setting will be memorized along with the frequency information.

    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-7800R includes a number of features which make repeater operation simple
    and enjoyable.

    REPEATER SHIFTS
    Your FT-7800R has been configured, at the factory, for the repeater shifts customary in
    your country. While the 144 MHz shift will be 600 kHz; on 70 cm, the shift may be 1.6 MHz,
    7.6 MHz, or 5 MHz (USA version).
    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-7800R provides a convenient Automatic Repeater Shift feature, which causes the
    appropriate repeater shift to be automatically applied 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 and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #4 (ARS).
    3. Press the [BAND(SET)] key momentarily, then rotate
    the DIAL knob to change the setting to “ON” (to enable
    Automatic Repeater Shift).
    4. Press the [BAND(SET)] key momentarily to save the
    new setting, then press and hold in the [BAND(SET)]
    key for 1/2 second to exit to normal operation.
    With repeater shift activated, you can temporarily reverse the transmit and receive frequencies by pressing and holding in the [TONE(HM/
    RV)] key for 1/2 second. Use this feature to display the transmit frequency without transmitting, and to check the strength of signals on a
    repeater uplink frequency (so as to determine
    whether of not a particular station is within
    “Simplex” range, for example).

    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 and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #33 (RPT.MOD).
    3. Press the [BAND(SET)] key momentarily, then rotate the DIAL knob to select the desired shift among “RPT.–,” “RPT.+,” and “RPT.OFF.”
    4. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold in
    the [BAND(SET)] key for 1/2 second to exit to normal operation.

    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 and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #39 (SHIFT).
    3. Press the [BAND(SET)] key momentarily, then rotate the DIAL knob to select the new
    repeater shift magnitude. The shift must be a multiple of 50 kHz.
    4. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold in
    the [BAND(SET)] key for 1/2 second to exit to normal operation.
    If you just have one “odd” split that you need to program, don’t change the “default” repeated shifts using this Menu Item! Enter the transmit and receive frequencies separately, as shown on page 33.

    CTCSS/DCS 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-7800R, 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 [TONE(REV)] key and Set
    mode #44 (TN FRQ).
    1. Press the [TONE (REV )] key several times, so that
    “ENC” appears on the display; this activates the CTCSS
    Encoder, which allows repeater access.
    1) You may notice an additional “DCS” icon appearing while you press the
    [TONE(REV)] key in this step. We’ll discuss the Digital Code Squelch system
    shortly.
    2) You may notice the “REV TN” indication on the display; this means that the Reverse Tone Squelch system is active, which mutes your FT-7800R’s receiver when it
    receives a call from the radio sending a matched CTCSS tone. The “DEC” icon will
    blink on the display when the Reverse Tone Squelch system is activated.
    2. Pressing the [TONE(REV)] key once more in above step will cause “ENC DEC” to
    appear. When “ENC DEC” appears, this means that the Tone Squelch system is active,
    which mutes your FT-7800R’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.
    3. When you have made your selection of the CTCSS tone
    mode, press and hold in the [BAND(SET)] key for 1/2
    second to enter the Set mode, then rotate the DIAL knob
    to select Menu #44 (TN FRQ). This Menu selection allows setting of the CTCSS tone
    frequency to be used.
    4. Press the [BAND(SET)] key momentarily

    CTCSS OPERATION
    the [BAND(SET)] key momentarily to save the new setting, then press and hold in the [BAND(SET)] key for
    1/2 second to exit to normal operation.
    Your repeater may or may not re-transmit a CTCSS tone - some systems just use
    CTCSS to control access to the repeater, but don’t pass it along when transmitting. If the S-Meter deflects, but the FT-7800R is not passing audio, press the [TONE(REV)]
    key so that “ENC” appears - this will allow you to hear all traffic on the channel being
    received.

    DCS OPERATION
    Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
    advanced tone system which generally provides more immunity from false paging than does
    CTCSS. The DCS Encoder/Decoder is built into your FT-7800R, and operation is very
    similar to that just described for CTCSS. Your repeater system may be configured for DCS;
    if not, it is frequently quite useful in Simplex operation if your friend(s) use transceivers
    equipped with this advanced feature.
    Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and
    that you select a Tone Code.
    1. Press the [TONE(REV)] key until “DCS” appears on
    the display; this activates the DCS Encoder/Decoder.
    2. Now, press and hold in the [BAND(SET)] key for 1/2
    second to enter the Set mode, then rotate the DIAL knob
    to select Menu #9 (DCS.COD).
    3. Press the [BAND(SET)] key momentarily to enable the
    adjustment of the DCS code.
    4. Rotate the DIAL knob to select the desired DCS Code
    (a three-digit number).
    5. When you have made your selection, press
    the [BAND(SET)] key momentarily to save 023 025 026
    the new setting, then press and hold in the 054 065 071

    until a matching DCS code is received on an
    incoming transmission. Switch the DCS off
    when you’re just tuning around the band!

    CTCSS/DCS OPERATION
    TONE SEARCH SCANNING
    In operating situations where you don’t know the CTCSS or DCS tone being used by another station or stations, you can command the radio to listen to the incoming signal and
    scan in search of the tone being used. Two things must be remembered in this regard:
    You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
    Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
    transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scanning to work.
    To scan for the tone in use:
    1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussion). In the case of CTCSS, “ENC DEC” will appear on the display; in the case of
    DCS, “DCS” will appear on the display.
    2. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    3. Rotate the DIAL knob to select Menu #44 (TN FRQ)
    when CTCSS is selected, or Menu #9 (DCS.COD) during DCS operation.
    4. Press the [BAND(SET)] key to enable adjustment of
    the selected Menu Item.
    5. Press the [SCAN(SEL)] key momentarily to start scanning for the incoming CTCSS or DCS tone/code.
    6. When the radio detects the correct tone or code, it will
    halt on that tone/code, and audio will be allowed to pass.
    Press the [BAND(SET)] key momentarily to lock in that
    tone/code, then press and hold in the [BAND(SET)]
    key for 1/2 second to save the new setting and exit to
    normal operation.
    If the Tone Scan feature does not detect a tone or code, it will continue to scan
    indefinitely. When this happens, it may be that the other station is not sending any
    tone. You can press the [SCAN(SEL)] key to halt the scan at any time.
    Tone Scanning works either in the VFO or Memory modes.

    Deleting Memories
    With 1000 “Regular” memories available (except memory channel “1”), there frequently
    are situations where you may desire to delete certain memorized frequencies. The procedure
    for deleting a channel is quite simple:
    1. Press the [V/M(MW)] key, if needed, to enter the Memory mode.
    2. Press and hold in the [V/M(MW)] key for 1/2 second, then rotate the DIAL knob to select
    the memory channel to be deleted. Note that memory channel “1” may not be deleted.
    3. Press the [SCAN(SEL)] key momentarily. The display will revert to memory channel
    “1.” If you rotate the DIAL knob to the location you just deleted, you will observe that it
    is now invisible.
    Note: Once deleted, the channel data cannot be recovered.

    HOME Channel Memory
    A special one-touch “HOME” channel is
    available (one for each of the five operating bands), to allow quick recall of a favorite operating frequency on each band.
    HOME memory storage is simple to accomplish:

    SCANNING
    The FT-7800R allows you to scan just the memory channels, the entire operating band, or
    a portion of that band. It will halt on signals encountered, so you can talk to the station(s) on
    that frequency, if you like.
    Scanning operation is basically the same in each of the above modes. Before you begin, take
    a moment to select the way in which you would like the scanner to resume scanning after it
    halts on a signal.

    Setting the Scan-Resume Technique
    Three options for the Scan-Resume mode are available:
    BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the
    carrier has dropped because the other station(s) ceased transmission, the scanner
    will resume.
    TIME: In this mode, the scanner will halt on a signal it encounters, and will hold there for
    five seconds. If you do not take action to disable the scanner within five seconds, the
    scanner will resume even if the stations are still active.
    HOLD: In this mode, the scanner will halt on a signal it encounters. It will not restart automatically; rotate the DIAL knob to re-initiate scanning if you wish to resume.
    To set the Scan-Resume mode:
    1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #37 (SCAN).
    3. Press the [BAND(SET)] key momentarily, then rotate
    the DIAL knob to select the desired scan-resume mode.
    4. Press the [BAND(SET)] key momentarily to save the
    new setting, then press and hold in the [BAND(SET)]
    key for 1/2 second to exit to normal operation.
    Note: The default condition for this Menu Item is “BUSY.”

    VFO SCANNING
    This mode allows you to scan the entire current operating band.
    1. Select the VFO mode by pressing the [V/M(MW)] key, if necessary.
    2. Press and hold in the [SCAN(SEL)] key for 1/2 second, then rotate the DIAL knob to
    select the bandwidth for the VFO scanner. Available selections are ±1 MHz, ±2 MHz, ±5 MHz, ALL, PMS-X,
    and BAND.
    ALL: The scanner will sweep all frequencies between 108 - 520 MHz and 700 -999.990
    MHz.
    PMS-X: The scanner will sweep frequencies within the currently-selected PMS frequency
    pair (X is PMS memory channel number). See page 45 for details.
    BAND: The scanner will sweep frequencies only on the current band.
    3. Press the [SCAN(SEL)] key momentarily to start scanning.
    4. The “P-XX” indication will appear on the display if
    you engage PMS scanning, while the “P SC” indication will appear on the display when other scanning
    modes are engaged.
    5. If and when the scanner encounters a signal strong enough to open the squelch, the
    scanner will halt temporarily; the decimal point of the frequency display will blink during this “Pause” condition.
    6. The scanner will then resume according to the Scan-Resume mode selected in the previous section.
    7. To cancel scanning, press the [SCAN(SEL)] key momentarily again (or press the
    microphone’s PTT key).
    1) When you start scanning, the FT-7800R will be changing frequency in the
    upward direction. If you want to change direction of the scan while it is underway,
    rotate the DIAL knob one click in the opposite direction (in this case, one click counterclockwise). You’ll see the scanner turn around and change frequency downward!
    2) Pressing and holding in the microphone’s [UP] or [DWN] key will cause the scanner to
    sweep frequencies only on the current band. If you would like the scanner not to be
    restricted to the current band, you may change Menu #46 (VFO.BND) to allow the scanner to hop to the low edge of the next-highest band when the VFO frequency reaches the
    high end of the current band (or vice- versa). See page 75 for details.

    1. Set the radio to the Memory mode by pressing the [V/M(MW)] key, if necessary.
    2. Press the [SCAN(SEL)] key to initiate scanning.
    3. As with VFO scanning, the scanner will halt on any signal encountered that is strong
    enough to open the squelch; it will then resume scanning according to the Scan-Resume
    mode set previously.
    4. To cancel scanning, press the [SCAN(SEL)] key again (or press the microphone’s PTT
    key).
    You may initiate the memory channel scan by pressing and holding in the
    microphone’s [UP] or [DWN] key.

    How to Skip (Omit) a Channel During Memory Scan Operation
    Some continuous-carrier stations like a Weather Broadcast station will seriously impede
    scanner operation if you are using the “Carrier Drop” Scan-Resume mode, as the incoming
    signal will not pause long enough for the transceiver to resume scanning. Such channels may
    be “Skipped” during scanning, if you like:
    Set the radio to the Memory Mode by pressing the [V/M(MW)] key, if necessary.
    Rotate the DIAL knob to select the Memory Channel to be skipped during scanning.
    Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    Rotate the DIAL knob to select Menu #40 (SKIP).
    Press the [BAND(SET)] key momentarily, then rotate
    the DIAL knob to “SKIP.” The current Memory Channel
    will now be ignored during scanning. The small “SKIP”
    icon will also appear when you recall the “Skipped”
    memory channel manually. The “ONLY” selection is used
    for “Preferential Memory Scan,” described in the next column.
    6. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold in
    the [BAND(SET)] key for 1/2 second to exit to normal operation.
    7. To re-institute a channel into the scanning loop, select “OFF” in step 5 above (the “Skipped”
    channel will still be accessible via manual channel selection methods using the DIAL
    knob in the MR mode, whether or not it is locked out of the scanning loop).

    SMART SEARCH
    The Smart Search feature allows you to load frequencies automatically according to where
    activity is encountered by your radio. When Smart Search is engaged, the transceiver will
    search above and below your current frequency, storing active frequencies as it goes (without stopping on them even momentarily); these frequencies are stored into a special Smart
    Search memory band, consisting of 31 memories (15 above the current frequency, 15 below
    the current frequency, plus the current frequency itself).
    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 discovers where the
    local activity is to be found, and automatically loads those frequencies for you.
    Two basic operating modes for Smart Search are available:
    SINGLE: In this mode, the transceiver will sweep the current band once in each direction
    starting on the current frequency. All channels where activity is present will be
    loaded into the Smart Search memories; whether or not all 31 memories are filled,

    ARTS™: AUTO RANGE TRANSPONDER SYSTEM
    The ARTS feature uses DCS signaling to inform both parties when you and another ARTSequipped station are within communications range. This may be particularly useful during
    Search-and Rescue situations, where is important to stay in contact with other members of
    your group.
    Both stations must set up their DCS codes to the same code number, then activate their
    ARTS feature using the command appropriate for their radio. Alert ringers may be activated,
    if desired.
    Whenever you push the PTT switch, or every 25 seconds
    after ARTS is activated, your radio will transmit a signal
    which includes a (subaudible) DCS signal for about one
    second. If the other radio is in range, the beeper will sound
    (if enabled) and the display will show “IN.RNG” as opposed
    to the out of range display “OUT.RNG” in which ARTS operation begins.
    Whether you talk or not, the polling every 25 seconds will continue until you de-activate
    ARTS. Every 10 minutes, moreover, you can have your radio transmit your callsign via CW,
    so as to comply with identification requirements. When ARTS is de-activated, DCS will also
    be deactivated (if you were not using it previously in non-ARTS operation).
    If you move out of range for more than one minute (two pollings), your radio will sense that
    no signal has been received, three beeps will sound, and the display will revert to “OUT.RNG.”
    If you move back into range, your radio will again beep, and the display will change back to
    the “IN.RNG” indication.
    During ARTS operation, it is not possible to change the operating frequency or other settings; you must terminate ARTS in order to resume normal operation. This is a safety feature
    designed to prevent accidental loss of contact due to channel change, etc. Here is how to
    activate ARTS:

    Basic ARTS Setup and Operation
    1. Set your radio and the other radio(s) to the same DCS code number, per the discussion
    on page 29.
    2. Press and hold in the [S.SCH(ARTS)] key for 1/2 second. You will observe the “OUT. RNG” display on the
    LCD. ARTS operation has now commenced.
    3. Every 25 seconds, your radio will transmit a “polling” call to the other station. When that
    station responds with its own ARTS polling signal, the
    display will change to “IN.RNG” to confirm that the other
    station’s polling code was received in response to yours.
    4. Press and hold in the [S.SCH(ARTS)] key for 1/2 second to exit ARTS operation and
    resume normal operation of the transceiver.

    ARTS™: AUTO RANGE TRANSPONDER SYSTEM
    ARTS Polling Time Options
    The ARTS feature may be programmed to poll every 25 seconds (default value) or 15 seconds. The default value provides maximum battery conservation, because the polling signal
    is sent out less frequently. To change the polling interval:
    1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #3 (AR INT).

    new setting, then press and hold in the [BAND(SET)]
    key for 1/2 second to exit to normal operation.

    ARTS Alert Beep Option
    The ARTS feature allows two kinds of alert beeps (with the additional option of turning
    them off), so as to alert you to the current status of ARTS operation. Depending on your
    location and the potential annoyance associated with frequent beeps, you may choose the
    Beep mode which best suits your needs. The choices are:
    INRANG: The beeps are issued only when the radio first confirms that you are within range,
    but does not re-confirm with beeps thereafter.
    ALWAYS: Every time a polling transmission is received from the other station, the alert
    beeps will be heard.
    OFF:
    No alert beeps will be heard; you must look at the display to confirm current
    ARTS status.
    To set the ARTS Beep mode, use the following procedure:
    1. Press and hold in the [BAND(SET)] key for one second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #2 (AR BEP).

    TIME-OUT TIMER
    The “Time-Out Timer” (TOT) feature is designed to force the transceiver into the “receive”
    mode after a preset time period of continuous transmission (the default is 6 minutes). This
    feature prevents your transceiver from transmitting a “dead carrier” for a long period of time
    in the event that the microphone PTT switch is accidentally locked in the “TX” condition.
    The Time-Out Timer’s “switch-to-receive” time may be adjusted, in one minute increments,
    for any period between 1 and 30 minutes.
    To change the default (6 minute) time setting, use the following procedure:

    DCS CODE INVERSION
    The DCS system was first introduced in the commercial LMR (Land Mobile Radio) service,
    where it is now in widespread use. DCS is sometime referred to by its different proprietary
    names, such as DPL® (Digital Private Line®, a registered trademark of Motorola, Inc.).
    DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data rate of
    134.4 bps (bit/sec). Occasionally, signal inversion can result in the complement of a code to
    be sent or received. This prevents the receiver’s squelch from opening with DCS enabled, as
    the decoded bit sequence would not match that selected for operation.
    Typical situations that might cause inversion to occur are:
    Connection of an external receiver preamplifier.
    Operating through a repeater.
    Connection of an external linear amplifier.
    Note that code inversion does not mean that any of the above listed equipment is defective!
    In certain amplifier configurations, the output signal (phase) is inverted from 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 received DCS code.
    While under most circumstances this should not occur (amplifier designs and industry standards take this into account), if you find that your receiver squelch does 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:
    1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select Menu #10 (DCS.N/R).
    3. Press the [BAND(SET)] key momentarily, then rotate
    the DIAL knob to select the following mode.
    T/RX N: Encoder; Normal, Decoder; Normal
    RX R: Encoder; Normal, Decoder; Reverse (Inverted)
    TX R: Encoder; Reverse (Inverted), Decoder; Normal
    T/RX R: Encoder; Reverse (Inverted), Decoder; Reverse (Inverted)
    4. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold in
    the [BAND(SET)] key for 1/2 second to exit to normal operation.
    Remember to restore the default setting to “T/RX N” (Encoder; Normal, Decoder; Normal)
    when done.

    RESET PROCEDURE
    In the event of erratic operation of the transceiver, it is possible that data on the microprocessor may have become corrupted. While this is a highly unusual situation, the only path ro
    recovery may involve resetting of the microprocessor. Here’s how to do this:
    1. Turn the radio off.
    2. Press and hold in the [MHz(PRI)] key while turning the radio on.
    3. Rotate the DIAL knob to select the resetting menu:
    F-1 SETRST: Resets the Set (Menu) mode settings to their factory defaults.
    F-2 HYPRST: Clears the Hyper Memory settings to factory defaults.
    F-3 MEMRST: Clears the Regular Memory settings to factory defaults.
    F-4 MB RST: Clears the Memory Bank Assignment.
    F-5 ALLRST: Clears all memories and other settings to factory defaults.
    4. Press and hold in the [BAND(SET)] key for 1/2 second to complete the reset procedure,
    once you have made your selection in step 3.

    CLONING
    You can transfer all data stored in one FT-7800R to another FT-7800R by utilizing the
    handy “Cloning” feature. This requires a user-constructed Cloning cable which connects the
    DATA jacks on the two transceivers, as shown below.
    To clone from one transceiver to another, use the following procedure:
    1. Insert the Cloning Cable into the DATA jack of each transceiver.
    2. Turn both transceivers off, then press and hold in the [MHz(PRI)] key on each radio
    while turning the power on again.
    3. Rotate the DIAL knob on each radio to select (F-7 CLONE), then press and hold in the
    [BAND(SET)] key. The display will disappear for a
    moment, then the “CLONE” notation will appear on the
    display.
    4. On the “destination” radio, press the [LOW(ACC)] key.
    The “- - RX - -” indicator will appear on the display.
    5. Now, on the “Source” radio, press the [V/M(MW)] key.
    The “- - TX - -” indicator will appear on the display, and
    the cloning data transfer will immediately begin.
    6. If there is a problem during the cloning process, “ERROR” will be displayed. Check your cable connections,
    and try again.
    7. If cloning was successful, “CLONE” will reappear on both displays.
    8. Turn both transceivers off, then remove the Cloning Cable. Channel and operating data
    for both radios are now identical. They both may be turned on now for normal operation.

    MENU (“SET”) MODE
    The FT-7800R Set (Menu) mode, already described in parts of many previous chapters, is
    easy to activate and set. It may be used for configuration of a wide variety of transceiver
    parameters, some of which have not been detailed previously. Use the following procedure
    to activate the Set (Menu) mode:
    1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
    2. Rotate the DIAL knob to select the Menu Item to be
    adjusted.
    3. Press the [BAND(SET)] key momentarily to enable
    adjustment of the selected Menu item, then rotate the
    DIAL knob to perform the actual adjustment.
    4. After completing your selection and adjustment, press
    the [BAND(SET)] key momentarily to save the new setting, then press and hold in the
    [BAND(SET)] key for 1/2 second to exit to normal operation.
    You may see the small letters “HYP” or “E CH” at the upper left-hand corner in
    the display while adjusting certain Menu items. These denote special characteristics of these particular Menu items:
    1) The “HYP” character indicates that each Hyper Memory may have distinct parameters assigned to it pertaining to this Menu item;
    2) The “E CH” character indicates that each Operating Mode (VFO, Memory Channel,
    or Home Channel) may have distinct parameters assigned to it pertaining to this Menu
    item.
