I will NOT merge this branch right now.
Being trying this morning on 40. It's not providing dramatically more spots, but it's not that easy to tell if there is or isn't an improvement. At this time of year, the bands go up a down a lot over quite short periods of time. If I get the chance, I'll try piping wsprd | wc with each branch.
BTW, another column in the output for offset would help in identifying wide bandwidth signals.
Thank you Guenal, however I don't think that I can make meaningful tests because I only have one antenna for HF and no external tuner, I use it with the internal tuner of my transceiver and one antenna for VHF/UHF, but there aren't WSPR transmitters on VHF/UHF near enough anyway.
I'll let this branch of rtlsdr-wsprd run overnight with this command line
./rtlsdr_wsprd -f 80m -u 125M -c IU5HKX -l JN53fj -w 80m_fir
, but for now I'm only getting wrong decodes

These are the .iq file for some of the spots above:
Yep, there is nothing visible on these sample. BTW, what kind of up-converter did you used? I will update to the latest version of wsprd, and hope for a fix with these wrong spots, otherwise, I will add a str cmp test to remove them.
My upconverter is a no-brand based on the NE602 mixer.
@dforsi I will finish this branch https://github.com/Guenael/rtlsdr-wsprd/tree/lib-update , and we will see if a recent version of wsprd fix this issue. Otherwise, I will drop this callsign.
Additional BW not required here (cf. decoding bw limited +/-150Hz by another FIR).
cc @dforsi @mkarliner you might be interested in testing this branch.
