Hi Bill,
That's an interesting theory but the evidence doesn't support it. If I
turn off VOX then WJST never puts the K3 into transmit. I looked and F2
in WJST-X has "VOX" selected under the Radio tab.
The more I mull this over the more the effect of turning the Mic pot
down to zero and back up again to temporarily clear the fault the more I
suspect the K3 firmware.
I've downloaded the latest microcode from electraft.com. So far this
evening the fault has not reappeared. Time will tell.

The type of radio might matter for a fix for the problem.
If wsjt-x is set up to use CAT control from the computer, it
will use CAT to set the radio into transmit mode, so the fact
that the radio is in transmit mode doesn't mean that VOX has
been activated. If this is the case, it is possible there is a
problem with the sound card/cable(s).

I'm an infrequent user of data modes. I'm trying to use FT8

Everything works OK on transmit except that intermittently the
K3 output falls to zero even though the sound card audio output
level isn't changing. The VOX stays on, so the K3 is "hearing"
the audio. ALC usually but not always falls to zero from the 4
bars level. Even weirder, if I turn the MIC gain (LINE) down to
zero and back up again the output and ALC come back up to normal.
Is this a hardware fault? A software fault? Or something even weirder? My FW
REVS says
uC 05.14
d1 02.83
d2 00.00 (no KRX3 is installed)
FL 01.19
