The popular SDRplay RSP1A -> A Wideband Full Featured 14-Bit SDR receiver. Gives an SNR of at least 5dB on the spectrum scope in GNU Radio (before filtering) A simple way to get video in and out of GNU. In my opinion, if for example the Osmocom Source sees the band from 900MHz to 920MHz is because the center frequency of the block is set to 910MHz (and sample rate of 20MHz), so I just have to make this parameter change (center freq) to see the "unknown signal" you're talking about, because the hackrf can see much further in the spectrum. The main category is Ham Radio Raspberry Pi projects that is about Raspberry Pi Ham radio projects. Got it almost working, but gnuradio kept reporting errors.
