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
