[WT-support] Strange problem switching bands with TRX connected by Omnirig and same IF

[Bob Wilson, N6TV]

I am currently updating the .INI files used by OmniRig for most modern Icom
radios, including the IC-7100.

Are you selecting IC-7100e4.ini?  There may be a problem in that it is
returning both VFO A and VFO B and "Operating Freq", and it's not clear
which one Win-Test will use.  If you press A=B does it make any difference?

Do you see the same problem if you set Radio type to IC-7100 instead of to
OmniRig?

What values are you entering in the Frequency Offsets dialog?  If you are
using the the 2m band on the radio for both 10 and 24 GHz, and switching
back and forth between 10 and 24 GHz, then I don't see any way for Win-Test
to display the proper frequency.  Win-Test is designed to mapping one band
on one band (2m in your case) to one other band, not one band to two other
bands.  Or are you you using TWO IC-7100s?  Are you using SO2R mode in
Win-Test?

73,
Bob, N6TV
