r820tweak VS librtlsdr

Have already tried r820tweak and r820tweak_patched but though they were both successfully built, there were issues, probably to script using Python 2.

Download the https://github.com/rtlsdrblog/rtl-sdr-blog or https://github.com/librtlsdr/librtlsdr version instead. Even try both, since there may be differences.

Give https://github.com/librtlsdr/librtlsdr a try?

I should have mentioned, I'm using this fork of the librtlsdr library, which contains a slightly different version of rtl_power with some extra features, and apparently the "-D" option is treated differently in the version I'm using. The forked version allows you to set a specific branch using the "-D" option, as described below:

There are a few variations of librtlsdr, f.e. this fork; https://github.com/librtlsdr/librtlsdr which adds features that aren't available in the version used in most Linux distributions. This adds some extra features and output that are really useful (most notably, regular output of max, min, mean power levels and noise floor). It also has some extra functions to fine tune signals.

Linux, librtlsdr and this port of DSD. FWIW, this port of DSD is newer and also has a Windows binary.

Next I moved onto try feeding the output of rtl_sdr (from https://github.com/librtlsdr/librtlsdr) to nrsc5 and that worked well!

You have an older librtlsdr; I'm using the GitHub version, which adds extra features; https://github.com/librtlsdr/librtlsdr

Thank you for your reply, I have tried it with the 'static' from the official GitHub https://github.com/librtlsdr/librtlsdr/releases , but the error remains? Do you mean an even newer version?

github.com/librtlsdr/librtlsdr may be worthy to check out.
