YAESU FT-712RH COMPACT 70cm FM MOBILE
TRANSCEIVER
The FT-712RH is a compact, full-featured frequency synthesized FM mobile/base
transceiver providing selectable power output of either 3 or 35 watts on the 70cm
amateur band. Unique features include the optional DVS-1 Digital Voice System,
which provides local and remote digital voice recording and playback when
installed in the FT-712RH.
Inside the FT-712RH, surface-mount components provide high reliability and
performance, while modular circuit construction makes servicing easy. An all-
new compartmentalized die-cast chassis provides superb rf isolation and
incredible overall ruggedness. A large liquid crystal display includes a bargraph
PO/S-meter. Ambient light is sensed to automatically control the brightness of
the display back-lighting and pilot lamps, dimming the display in dark
environments.
Operating features include memory selection and tuning in 5, 10, 12.5, 15, 20 and
25 kHz selectable steps; The channel memory system includes 19 general purpose
memories, a one-touch recall CALL channel memory and two subband limit
memories (for programmable subband scanning); one-touch repeater reverse;
band and selected memory scanning with auto-resume after carrier-drop or 5-
second pause, and priority channel monitoring. Memory hiding and scan-skip are
easily settable.
Twenty of the memories store either programmable repeater shift or independent
transmit and receive frequencies. When the optional FTS-12 Tone Squelch unit is
installed, any of 37 standard CTCSS (subaudible) tone frequencies can be
displayed, selected and programmed into any memory channel for either silent
monitoring or encode-only operation.
The microphone jack includes signals for CAT System control from an external
personal computer, and memory cloning to/from other FT-712RHs. A 1750 Hz
burst tone generator is built-in and can be activated from the MH-14A8
Speaker/Mic. DTMF keypad microphone options include the MH-15C8 and the
MH-15D8 with its own auto-dial DTMF memories. If the burst tone is not
needed, an internal jumper can be set to allow packet radio tnc interfacing via the
microphone jack.
