FT-7900R O

The FT-7900R is a ruggedly-built, high quality Dual Band FM transceiver providing 50

Watts of power output on the 144 MHz Amateur band and 45 Watts on the 430 MHz Ama-

teur band.

The high power output of the FT-7900R is produced by its RD70HVF1 Power MOS FET

amplifier, with a direct-flow heat sink and thermostatically-controlled cooling fan maintain-

ing a safe temperature for the transceiver’s circuitry.

Featuring 1055 memory channels which enable the storage of Independent Transmit Fre-

quencies (“Odd Split”), and built-in CTCSS and DCS encoder/decoder circuits, the

FT-7900R 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

™ (Wide-

Coverage Internet Repeater Enhancement System), a transmit Time-Out Timer (TOT), Au-

tomatic 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 communi-

cations 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-7900R transceiver.
