APPLICATION HINTS
MARS/CAP Coverage
The AT-1000 Pro provides continuous tuning coverage over its specified range; not just in
the ham bands. This makes it useful for MARS or CAP operation, or any other legal HF
operation.
Icom Radio Interface
The AT-1000 Pro offers integration with many Icom transceivers, including the IC-7000 and
IC-706. Simply plug the 1/8" plug of the optional Icom interface cable into the Radio Interface
jack on the back of the AT-1000 Pro, and plug the 4-pin Molex plug into the matching jack on
the back of the radio.
Tuning can then be performed by first bypassing the amplifier, and then pressing and holding
the TUNE/CALL button on the Icom radio for 1 second. When tuning is complete, the amplifier
may be placed in active mode again. Momentarily pressing the TUNE/CALL button on the
radio after the AT-1000 Pro has tuned will place the AT-1000 Pro in bypass mode.
Optional Yaesu Radio Interface
The AT-1000 Pro also offers integration with Yaesu FT-857, and FT-897 transceivers. Plug
the black end (marked "Tuner") of the optional Yaesu interface cable into the Radio Interface
jack on the back of the AT-1000 Pro, and plug the red end (marked "Radio") into the ACC jack
on the back of the FT-857 or FT-897.
Tuning operation is the same as described in the section on Basic Tuning, except that when a
manual memory tune or full tune is requested, the AT-1000 Pro will send a signal to the FT-857
or FT-897 requesting that the radio begin transmitting a low level carrier. Once again, be sure to
bypass the amplifier before requesting a tuning cycle in this case, and then re-activate the
amplifier once the tuning cycle is complete.
Build-Your-Own Interface
The Radio Interface jack on the rear of the AT-1000 Pro follows the same format as most
Icom transceivers' Tuner interface. The
1/8" stereo jack features a Start input,
which requests that the AT-1000 Pro
begin a tuning cycle when this input is
grounded momentarily (450-600 ms). It
also features an open-collector Key
output, which the AT-1000 Pro shorts to
ground when it is requesting that the radio
should key up and transmit a carrier.
