K3S/USB Cable/Mac mini/WSJT-X

[Richard-6]

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.

Cheers,

Richard Kunc - W4KBX

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

If it works in the afternoon and not in the morning, it is possibly a temperature related anomaly.  Unclear which hardware component is the cause, but possibly not a driver problem per se.

Have you tried slowing the baud rate down to 19200 when it's failing to see if it will work at the slower speed?

I have run a K3 as low as 9600 to perfect effect.
