New version can't decode what an older version is able to #104

I have been using dab-cmdline on my raspberry 3B for quite a while on 32 bit debian buster with a sdr usb stick. I upgraded to 64 bit bookworm. I tried updating the libraries but with the latest version I cannot pickup any of the stations. If I use the version I had from several years ago, it works (most of the time).

I'm not sure if there's anything I can do to try and track down the issue?

from the output it seems that the gain is not set for the rtlsdr device, I'll have a look tomoroow

When I run with a similar configuration on example 3, i.e. an RTLSDR device, I get a list of gain values, Found Fitipower FC0013 tuner samplerate set to 2048000 Supported gain values (23): -9.-9 -7.-3 -6.-5 -6.-3 -6.0 -5.-8 -5.-4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7 effective gain: gain 18.8 there might be a DAB signal here

Since I do not have a decent antenna that fits on the connector I do not get an ensemble, but reading the code, tou should get some output there then at least you can see the actual gain best jan

Thanks for the quick feedback.

I did notice that the list of gain values was missing. C/C++ is not my preferred language but I will see if I can take a look in the next week or two and see if I can troubleshoot why it is not showing the supported gain values.
