polls the tansceiver every 500ms since these rigs do not have a Transceive function.
Operation
The set of commands (from the PC) is variable from one model to the other. Due to the large
number of commands available and their diversity, only the most important commands for
real-time control are supported by TRX-Manager. These commands are available from the
Monitoring and Levels windows. Additional commands can be programmed using macros. Please
see your manual for the available commands.
You have to set up the Filters (FIL1-N, WID/NAR...) by defaut for each Mode from the
Preference/transceiver dialog box (See also Modes and Filters). From the
Preferences/Transceiver dialog, you may also enable the AUTO PBT function (see below).
If your transceiver supports the PBT and DSP Width functions, TRX-Manager provides two
very convenient functions :
Auto PBT (IF-Shift)
From the Preferences/Transceiver dialog, you may set up the default values of PBT Inside
and PBT Outside for each mode. These values (ranging from 0 to 255) apply for both the
Outside and Inside PBT commands and allow defining an IF-Shift (i.e SFT= -150hz for a value
of 110 but to be tested...). 128 is the factory default values (click D to reset factory
defaults).

PBT Ouside for each mode
Graphical display
The Monitorings' window displays the PBT Inside and Outside bandwidths (values
approximated).

Note about the speed of communication
ICOM transceivers automatically communicate frequency and mode changes but other parameters
(channel number, Split mode, VFO…) that are made on the transceiver are not transmitted to the
computer. The consequences are the following:

After TRX-Manager is started, some parameters are fixed by default or unavailable. The display
progressively becomes available as commands are sent from the PC. If necessary, rotate the
dial tuning to display the frequency,

It is thus recommended to change the VFOs or to switch the SPLIT mode from the PC.

TRX-Manager does some polling of important data but gives a priority to the most critical data
(Mode, S-Meter, TX State...). Consequently the other parameters (like PBT, DSP) may refresh
slowly...
