I had similar symptoms with both CAT PTT and VOX on. Turning VOX off fixed the problem.

Doug,

Thought I was home free last night (Jan 24). My final recipe was this:

RADIO Panel:
Rig: K3s
Poll Interval: 1 s
CAT Control
Serial Port: /dev/tty.usbserial-A60092F3
Serial Port Parameters
Baud Rate: 38400
Data Bits - Eight
Stop Bits - One
Handshake - None
Force Control Lines - both blank
PTT Method - CAT
Mode - Data/Pkt
Split Operation - None

AUDIO Panel: USB Audio CODEC at computer and WSJT-X

The PWR slider is set to produce ALC of 4 solid bars and 5th bar fluttering.

I spent four or five hours working DX with it on 30-meter FT8 last night, and that setup worked PERFECTLY every time: Transmit start and Transmit stop times right on the money. I mean, it was PERFECT!

I thought I was home free. I took screen shots of every Preference panel, the Mac Sound thing, even the Audio MIDI Setup panel in the Mac mini.

BUT! When I fired it up this morning (Jan 25), it was right back to starting Transmit late and not coming out of Transmit… at all. I have to tap the XMIT button to stop it. What the hell??? What could change overnight? I didn’t touch anything when I shut down last night or when I fired up this morning.

HOWEVER, as the afternoon and evening arrived, those symptoms went away and the setup was perfect again!

MORE HOWEVER, This morning, Jan 26, the symptoms were back again. I’ll take another look this afternoon, but this is getting spooky.

ANY and ALL ideas and suggestions will be MOST welcome, up to and including (if absolutely necessary), replacing the driver.
