I just tested and i could not make it work. Indeed, this backend and hence the package needs updating (the current version of that library is 8 not 7). But the other backands do not work too, at least in my case.
I am currently usind a rtl based tv tuner with rtl-sdr and gqrx, it works.
p.s. i did some more testing, installed all the backends, restarted… it kind of works, but it is a mess.
Tested backend soapy_power - works, shows curved graphic where the analog radios are in the upper window, the lower window where i guess the waterfall is supposed to be, remains empty, python error in waterfall graphic
Traceback (most recent call last):
File "/usr/lib/python3.12/site-packages/qspectrumanalyzer/plot.py", line 289, in update_plot
self.waterfallImg.scale((data_storage.x[-1] - data_storage.x[0]) / len(data_storage.x), 1)
TypeError: scale(self): too many arguments
Tested backend rx_power: error while loading shared libraries: libSoapySDR.so.0.7
That is because soapysdr is now at soname 8
extra/soapysdr 0.8.1-5 [installed]
usr/lib/libSoapySDR.so.0.8
usr/lib/libSoapySDR.so.0.8.1
Tested backend rtl_power - rtl_power: invalid option – ‘r’ but it detects the device.
As previously said, maybe look for the github and file an issue
Oh i just looked…seems the project is abandoned from its developer (the same waterfall bug is open since 3 years).
So the only thing left is to try a rebuild (you can write the arch packager Jelle Van der Waa jelle@archlinux.org)- that might fix rx_power/soapysdr version, but it will not fix anything else including the waterfall.
My advice is still to leave it. Gqrx works. I use the appimage Release Gqrx SDR 2.17.5 · gqrx-sdr/gqrx · GitHub
