Hello everyone,
the thread is already older, but if it helps anyone, here is my solution to the problem.
I also use the Warthog Throttle and have noticed that the radio switch sometimes triggers two key presses at the same time (e.g., when you rotate it quickly). When that happens, VA/VP gets out of sync.
Therefore, I added a safety check for the push-to-talk commands. It is important that for these commands, the simultaneous execution of other commands is disabled (so that the entire code is executed atomically and no race conditions can occur when checking the variable).
In the two screenshots, you can see an example for "press" and "release" respectively. This needs to be implemented accordingly for all used channels (adjust the variable value accordingly). The command sequence can be supplemented via "Other > Advanced". The variable TXACTIVE holds the channel that is currently being transmitted on (e.g., 3 for TX3). Thus, only one channel can be transmitted on at the same time.
This workaround works quite well for me. I hope it can also be useful for someone else.
Best regards,
Azmo
