By Scotty Cowling, WA2DFI – TangerineSDR’s roots extend back to the 2018 ARRL/TAPR DCC in Albuquerque, NM. At that conference, the HamSCI[1] community asked for TAPR’s help in developing a Software Defined Radio that they could use to collect ionospheric and other data. This radio, dubbed the Personal Space Weather Station (PSWS), needed particular capabilities, such as very accurate time-stamping of RF samples, ability to measure small fluctuations in the earth’s magnetic field and most of all, capability to share data over a large network of receivers.
