Introduction - Yaesu FT-7800R Operating Manual

NTRODUCTION
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 Ama-
teur 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 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-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 (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 ARTS 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.
