Tim and others,
When you want to use a UHF TRX with SSB and VARA-HF both STNS have to be EXACTLY on the same frequency!
A difference of more than 100 Hz could be that there is no connection possible.
Work around 1
When STN A press the TUNE butten (in VARA-HF), STN B can play with the RIT knob for the peak on 1500 Hz in the waterfall.
After? that this proces STN B hit the TUNE button and STN A turn on the RIT knob for 1500 Hz in the waterfall.
Work around 2
Me is told that another solution is to use VARA-SAT.
I have no experience with this solution.
The best preformance is to use VARA-FM in WIDE mode, with licence ($50?), on a FM-TRX with "9600 bd" connection.
Avoid transformers in the audio interface (external soundcard) and avoid using VOX.
After building (bad) audio-interfaces with problems I can advice you the next audio-interfaces:
Manufacture 1:
Manufacture 2:
Good luck and best '73
