Hi all,
I may have overlooked but could not find any setting in VarAC for TX delay to prevent the transmitter from hot keying.
Or is that build in the software ?
Also, I have a KPA500 amplifier. At times It auto swiches to 24 Mc while I am transmitting on 28 Mc. Even with the KPA only driven to as low as 100 Watts output. It never happens on FT8 nor on FT4 even not with the KPA driven to full ouput of 500 Watts.
Could that be the signal width of the transmitted VARA signal ? It looks rather wide on the waterfall of my FLEX-6300 wich is certainly not overdriven.

ARQ modes and TX delays do not mix. From the moment the Modem tell VarAC to PTT ON, you dont have any time to waste as the sound is comming a few milliseconds afterwards.
