Occurred now with two OMs of a similar constellation: PTT configured by DTR/RTS. Selected as VARA modem type: VaraHF, selected for the QO100 varasat.exe. In the settings we can try PTT and the transmitter is also keyed.
However, no PTT is switched in the working window.
If select "VaraFM" as the VARA modem type, then the PTT is switched.
Shouldn't it also work with VaraHF? Settings like this

Hi @Tommi
As mentioned above - it is not a bug. If you want to use VARA SAT although not supported - you have to configure VarAC to use VARA FM. The technical details of why a PTT test still works regardless to what modem type you chose is described in details in my previous answer, 73s

Not strage at all. totally expceted.
When you do the test PTT, I do not wait for the modem to tell me to key the PTT. I key it on your click demand.
However when you try to connect someone, I wait for the modem to tell me when you Key the PTT ON and OFF.. if the modem does not tell me do it (as he did not accept my CONNECT command), I simply do not do it :)
Hello Irad,
Thanks for the answer.
In the "VARA commands" window it actually says "WRONG".
However, what I find strange is that in the config window, the "TEST PTT ON" and "TEST PTT OFF" buttons work.
Hi Thomas.
Got you VMAIL today .Thanks for he reminder :)
If you try to connect/CallCQ/Beacon then it wont work with VARA SAT when VarAC is set to VARA HF modem type. the command set of the modems is different between SAT/FM and HF.
I guess what you see is the word "WRONG" on the "VARA Commands". This is an indication that the modem is given a command it does not support. Vara SAT and FM has a similar command set which is different then the VaraHF modem.
Once you can not tell the modem you want to connect a station, the modem does not tell VarAC in return that it needs to key the PTT. So it is not a PTT problem but a problem that you set VarAC to work with VaraSAT while it is sending it connect command that it does not recognize.
Officially I do not support VARA SAT and did not do any adaptations for it. But it works with settings VarAC to VARA FM as you already discovered yourself.
73s!
