Specifications

CAT

if your transceiver supports setting up RF Power via TRX-Manager, please check POWER
VIA CAT and preset required RF Power values in Watts (*) for TUNE and NORMAL:
10-20W of input drive power are recommended by ACOM,

select Tuning Mode (FSK is preferable).
(*) CAT values in Watts for POWER are indicative values only, not always very accurate
(especially with ICOM transceivers) and may require adjustments.
You start AUTO-TUNE by pressing START and you follow instructions on screen. If your
transceiver does not support RX/TX and/or RF Power via CAT, you are prompted to
do changes and settings manually. During the Analysing step, you can press OK if you
estimate Drive power properly adjusted: Then, TRX-Acom skips this step and immediately
starts tuning.
TRX-Acom follows ACOM's recommendations with an adjustment of RF Power up to display 7
FWD Leds ON (2) before starting Tuning. Once a good Tune is found, it is memorized
automatically and your Transceiver comes back to the initial frequency and mode.
If any problem or abnormal behaviour happens during the procedure, press STOP.
Watch dog
If Watch Dog is checked in Setup and no command sent to the amplifier during the
sepecified delay, TRX-Acom will switch to Stand By .
ACOM Antenna Selector
If you use the ACOM Antenna selector, please check Antenna Switch in Setup ; if you don't
use it, it is preferable to let this option unchecked since it adds useless control commands
between amplifier and computer.
ACOM antenna switch is fully supported either using the TRX-Acom's antenna table (if enabled
in Setup) or amplifier's memorized antenna positions. Other available options (with antenna
table checked) are:

TX freq (default). If checked the TX Frequency defines the current segment

Hysteresis 25kHz (Default) from the edge of each segment to prevent from undesirable
antenna changes

Remember changes by HAM BAND. By default, TRX-Acom memorises an antenna
change for the corresponding segment and during a same session. If this option is enabled,
the memorization of an antenne change (from buttons 1-10) applies for the whole HAM
Band.
