Receiving COSPAS-SARSAT transponder on board of a low earth orbiting satellite on 1544.5 MHz (frequency on the SDR display was not calibrated, please ignore). Using the famous RTL SDR…”the cheapest SDR in town”” for VHF/UHF/SHF covering 64-1700 (up to 2.1 GHz “out of spec” )….this particular one was a Hama Nano. Sorry for the crappy cell phone video
