My father is really big into HAM radio (QRZ Callsign Database Search by QRZ.COM and then searching for his call sign: NZ5E). I'm always looking for ways to support his hobby. He has really been wanting to buy a SDR, but the majority of them are just too dang expensive. I've looked into a HackRF, but I feel like the same could be done for considerably less using a Raspberry Pi. He is mainly wanting one for analyzing the bands to easily pick out where to tune his radio for a QSO. I would love if you would be interested in making it a project for your YouTube viewers and myself. I want to do this for my father, but just have absolutely no idea where to start.
