[Elecraft] Fwd: New K4 WSJT-X fork for Remote K4 users

[Tim Tucker]

All,

I released a new build tonight which addresses a few reported issues,
including JTAlert compatibility, High SWR detection, and an issue that
could cause the tone input calibration to go wonky if there was another
remote device like a K4/0 or QK4 connected at the same time.  Give it a try
and let me know if you run into anything new.  Remember, I'm only changing
K4 remote related connectivity and stream capabilities, not core WSJT-X RC
things.

I'd like to see some users test this while using another remote app or K4/0
at the same time to make sure everything plays nice.  I like Log4OM and
have successfully tested integration with that.  JTAlert seemed to work ok
for me, but I've never really used in the past so I'm not the best test
case.

Here's a link to the latest build:
