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 Amateur 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 Frequencies (“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 WIRESTM (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 ARTSTM (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.
