A practical look at radio timekeeping for prepping, including LF and HF time stations, GPS time, useful gear, and how to build a reliable layered system. In this video I receive a time signal with a PRC-320 military manpack radio on 10MHz. The Casio shown is the GW-M5610U-1ER. Apparently the station I received on 10MHz was the Italian station JN53DV! (thanks F4ISS).
