There's some truth in it, as I'm using voice control and no keys! Yes, I am new and have at times forgot to use the "Roger "voice command but this isn't all the time.
I will do another test flight tonight ensuring Roger used all the time.
To clarify, are you saying that when using voice control software, I still have to press a key to Roger an art instruction?
I did not find a single Roger/Readback in your log!
You do not have to press the key yourself, but your voice control software has to (virtually) press it.
Maybe it does not send the correct key?
Possible pitfalls:
1. By default it is just "\" (not Ctrl-Shift-\ as for many other keys)
2. "\" is often used as an escape code by various software products, so maybe the software does not know what to send for a single "\"
You can test this key by sending the output of your VR program to something else (notepad, input box in a browser, ...).
And you can change the hotkey in PF3's settings.
