AppImage built on Xubuntu 16.04 LTS. Seems to work on 16.04 LTS and 18.04 LTS but I got ALSA/Pulseaudio issues on 22.04 LTS (it crashes while startup).
So, this is only a try and may work or may not for you.
It is the latest state of https://github.com/JvanKatwijk/sdr-j-fm/commits/master ( 5f6ba97 ) (V3.15) plus (my not yet included by JvanKatwijk) pull request.
