I find incredible that WSJT-X can decode two signals on the same
frequency, one very strong and the other very weak

Hi Jean Louis -
I believe that the problem is fixed now.

Jean Louis,
I am aware of the problem. I think that this regression was introduced when we
did a wholesale switch from double to float in wsprd.c. I will fix this, but it
may have to wait til the weekend.

Hi Bill
Totally agree with your analysis but I have so far failed to identify in
wsprd.c where to make the change ! It must be obvious and I am sure it is
fixable specially as in 1.6 it was ok according to my tests. I will do a
compare tomorrow or I am sure Steve will point me to the obviou

Hi Steve and team
Not sure if you saw my previous email following your attempt to reproduce the
problem , but I am looking for more help to correct the reported Rx frequency ,
if you inject a perfectly stable 1500Hz WSPR2 signal (drift reported = 0) ,
and just change the RX band on versi

Then, as some suggest, it might be a good time to consider retiring the
slider, while retaining the thermometer. Not a "stop the presses"
change, but it might be a good usability bump. Perhaps even a color
coded indication for the dB-impaired?

The gain slider does

I've found most all offsets less than 100Hz are due to poorly calibrated rigs.I
usually contact them to let them know and have helped a few get their rigs
calibrated.
Any movement due to QRM is usually more than 200Hz away.

Title: Re: [wsjt-devel] QSO Problem
Hello Dan,
you started at 2516/2517 Hz your QSO and PA3CPS came back at 13:18 at 2781 Hz
Therefore it's in the band activity. Guess PA3CPS clicked around and set his
TX frequency to 2781 Hz.

That's because his offset was more than 10Hz different.That's the window WSJT-X
uses to determine "same frequency". JTAlert has an adjustable freq width for
an alert on the Rx window.Usually means their rig isn't calibrated very well.
Don't see it real often.Sometimes they will move offset due
I just had this QSO with PA3CPS (See screen capture

How does the displayed input level relate to dBFS (decibels related to full
scale)?

Hello,
First, I am late with my translation to Spanish but I will have time next week
(finally!).
And I've been wondering about proper gain staging in WSJT-X for optimum
reception. The manual suggests adjusting the input level and RF gain until the
noise level is at around 30 dB according to t
