Tell us about yourself!
Aha, noted that it is rtl_fm that causes this problem. I did not use the keenerd fork of rtl-sdr but rather the "original". It seemse to lack support from RIFF / Wave(?) ..Reinstalled my pi from scratch and got things going!My Discone antenna (the roof installed attenuation ;) ) is doing a very poor job with circular polarized signals. Will build myself a better antenna!Again, thanks for all the scripts! <3
