1FT-7800R OPERATING MANUALThe FT-7800R is a ruggedly-built, high quality Dual Band FM transceiver providing 50Watts of power output on the 144 MHz Amateur band and 40 Watts on the 430 MHz Ama-teur band.The high power output of the FT-7800R is produced by its RD70HVF1 Power MOS FETamplifier, 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, theFT-7800R includes also provision for remote-head mounting, utilizing the optionalYSK-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 theowner to set the squelch to open at a programmable setting of the S-Meter, thus reducingguesswork in setting the squelch threshold.We recommend that you read this manual in its entirety, so as to understand fully the manyfeatures of your new FT-7800R transceiver.I NTRODUCTION
