Hi,
Just hooked up a sniffer to WSJT and the PTT CAT commands are correct,
putting it into transmit when appropriate and out as well. (Unless there is
an intermittent bug).
If the radio menu for PPT-KEY is OFF-OFF it cannot get put into transmit via
hardware. So, DTR signals do nothing. There will be no issue when you
power up your PC etc.
Since the K3 will go into transmit anyways, the most likely item then is
LPBridge (which the OP said he was using) OR VOX is enabled on the line-in
in the rear and the sensitivity is just too high.

Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx
For those using WSJT-X, sometimes I find
the K3s is locked as transmit but there is
no RF being sent and no Rx from the K3.
Looking at the P3 I see a jitter on the
upper half of the screen as if there was a
tiny output but no Rf is seen on any of
the three SWR meters in line (K3s, AP3 &
LP-100A).
I couldn't get WSJT to receive, looked at
the settings, all were correct and as is
sometimes needed with WSJT-X, I rebooted
to get it to work properly but it still
did not lock onto the K3s frequency.
Rebooted again and then I realized the K3s
was in that TX condition with both the red
& yellow LEDs lit and that jitter on the
P3 upper screen.
This happens every so often and what I
have to do is touch any of the buttons on
the K3s and it disengages this situation.
I did that to deal with the issue I
mentioned above. I could restart the K3s
but then I'd have to restart LP-Bridge and
wait, so I use the quick fix.
Anyone experience this and figure out how
to prevent it?
Thanks!
