Problems with PTT via SmartSDR CAT (foot switch)
My setup: Flexradio 6500, SmartSDR 3.2.39, Windows 10 21H2
I connected a foot switch for PTT to a serial port via SmartSDR CAT.
Sometimes the radio doesn't go on the air. There is no transmission power out.
But I can see the audio control and TX flag. See picture below.
If I then release PTT and press again, it usually works but not always.
Pressing MOX with mouse within SmartSDR does alway work.
