Hi Bill Many thanks once again for your very generous reply to my query.
I am running an FTdx-5000 barefoot into a full size 160m dipole and using CAT control. The speech processor is turned off. Audio is being fed via the front panel mic jack from a Mac Mini. The A3J TX passband is set at 400-2600 Hz. VOX is turned off. After quite a bit of fiddling this morning with mic gain, bandwidth, power settings and other controls I am unable to keep it from crashing the audio at the start of each transmission, as described in my previous post. If I turn the power setting on wsjtx very low then wait until the transmission begins I can then increase the power without crashing the audio. I can advance the power to the fully capability of the FT5k, i.e. 200w. Is it possible to disable / enable the CAT connection to wsjtx via UTP? If I could do that, I could use some software grab the CAT line then command the rig to increase the power after wsjtx initiates the transmission cycle and then return CAT control to wsjtx at the end of the transmission cycle. If you have any further ideas, I would love to hear them. Many thanks 73, Ed W1KOK
