Warning
If you encounter RFI (Radio Frequency Interference) on your computer, it can lock up while your
transceiver is keying. Consequently, please always watch your transceiver's status and make sure
you can stop keying manually in all situations.
Synchronization for band changes
If your amplifier provides a data input RS-232 ICOM or Kenwood compatible like the most
recent solid state amplifiers (Tokyo HP, Expert 1K-FA, IC-PW1...), you may configure
TRX-Manager as a Kenwood or ICOM/ICPW1 serial server and automatically control band
changes: see Synchronization.
The Band decoder can also be used to make band changes from the 8 pins of a parallel port
(i.e by using the Yaesu BCD format).
Linear Reminder, OPR/STBY control, support for digital wattmeters
The Linear Reminder module can be used to display Preset Tuning Settings of a manual linear
amplifier or with a LP-100 & LP-100A or ALPHAPOWER (4500) or Elecratft W2 Digital wattmeter
adding various additional functions. The Linear Reminder also provides a Standby/Operate
function which may help to prevent from transmitting with the linear on certain prohibited
segments or just after band changes or by drive power.
Automatic Drive power control
If your transceiver supports setting of Power output via CAT, you can use this feature to
automatically adjust the Drive power to the required values for the different bands.
Power output values by bands are set from the Preferences/Transceiver/Rotor... The
Auto-Parameter check box must be checked. If power is left blank, no power control is done.
