A while ago I added S-Meter readings to WSJT-X (added the dB level to the
"Receiving" box) and experimented a bit.
Problem I ran into was rigs were pretty unstable on what they reported so I
abandoned it.
My rig was rock solid but others that helped test it were getting erratic
answers from their rigs so the general usefulness seemed limited.
Of course, having it as an option box kind of solves that problem. But
would open up many reports of "SMeter is wrong" bug reports which may not
be fixable from what I saw and would drive the maintainers nuts I think.
Plus I found quite a few rigs in hamlib not reporting standardized answers
so quite a few rigs would need to be changed to.
You can run WSJT-X through hamlib rigctld-wsjtx and do your own S-Meter
query then from rigctl-wsjtx using "l STRENGTH" while wsjt-x is running.
I may try and implement this again (something to play with over the
holidays) -- unless there's a strong opinion that it's not worth it.
Attached is a program I wrote that displays time, db, avg db, max db on a
5-second window. Used it to test antennas on the Baofeng and also for our
radio club to do an HT shootout to see who could transmit the strongest
signal from their handheld to my home system. Used TeamViewer on my phone
to connect to my computer at home and watch the dB reports on my home
computer. You'd have to modify for your rig parameters and whatever values
you want printed out.
