I installed wsjtx-2.1.2.tgz to my Raspberry pi and have been enjoying.
I have some problems on 40m band wspr mode.
If the frequency setting of wspr is less than 7.040MHz such as 7.0386MHz, TX/TUNE
does not work. I tried other frequency/modes, but TX/TUNE works well.
I am also using wsjtx/wspr on my windows10 PC, but there are no such problems.
