I think default settings has this problem, to fix:
File/Settings/General/check - Disable Tx after sending 73
Even worse is this:
You're sitting and waiting, and a super rare DX shows up
You call, and nothing happens??!?
Finally you realize you have no Tx Power, WSJT-X isn't generating audio (even though your PC never sleeps).
You quickly kill WSJT-X, and Restart
You enable Tx, and suddenly 6 stations are calling you, and the DX is long gone. You're calling CQ unintentionally.
Is there some way to inhibit/prevent CQ? If 50 stations are always calling CQ, what's the benefit?
