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

[Thomas Sullivan]

Doing a bit of testing with the released 3.0.2 WSJT-X and JTAlert, it appears that JTAlert won't connect to WSJT-X until WSJT-X has a connection to the radio.  If I bring up WSJT-X without the radio connected, and click Configuration to clear the WSJT-X reconnect dialog, JTAlert has the same, unable to connect behavior with the released WSJT-X as it does with the K4 test version.  So, there is apparently some signal (likely on the IP port for reporting) that is generated when WSJT-X connects to the radio that is not being sent with the K4 version.  This seems pretty likely as the Radio connect logic is obviously brand new.  So I suspect this is where the disconnect is occurring.

Let me know if I can do any testing to help!

Thanks and 73!

I haven't tested JTAlert - I will do that later and see what happens.

Regarding other things like fonts, buttons, etc. - those are things in the core WSJT-X app that I didn't change.  So if you're seeing something broken like fonts being wierd, or buttons doing odd things, I would compare against the regular RC1 to see if the same behavior exists there...it's all inherited in my fork.

Re: high SWR indicator - that is an interesting one that I hadn't thought
about: A little research tells me that regular app uses hamlib to get that info from the rig.  But we're not using hamlib in this build because we're going direct to the radio, which means I need to account for that.  I'll get that added to the list of things to address.

One last thing that I DID change that I didn't mention before:  The stock WSJT-X uses the "power" slider to control audio drive from the PC to the radio. But that doesn't apply here, so I changed it to control the actual rig power control.  Keep in mind that the way I implemented the Auto TX input calibration, it sets the drive level by watching the ALC meter and it won't increase the audio input drive past an ALC reading of 5 to keep the signal nice and clean.  So even if you have the power set to 100 watts, you may actually see something a bit less than that if you're sitting next to the radio.
