Hello Bob,

thank you for the quick answer.

see below.

The Frequency Offsets are ok (I'm using that already), but as the
frequency Win-Test "sees" is just the 146MHz from the IF (IC7400), this
information alone does not help.

How could I pass back the correct frequency? Through wtRadio:SetFreq()
below?
Omnirig is maybe an option indeed. Just not sure how to customize it
(apparently it is open source and written in Pascal).

Yes, but my idea was to do it the other way round: external hardware to
tell WIn-Test the current band by "simulating" key strokes...

Ok, if I call SetFreq(), Win-Test would switch bands? So lets assume I
keep the current Radio setup (IC7400 aka IC746Pro) and would call
wtRadio:SetFreq() e.g. with a frequency in the 3400MHz band, it would
read out the Frequency Offset definition, send out the resulting 146MHz
frequency to the radio and switch internally to 3400?
If that works, that might be an option indeed. Then I could use your
script to open a serial interface to get the correct band.
I'll do a quick check to see...
