description Heathkit SB-500 Overview
The Heathkit SB-500 is a 2-meter single-sideband transverter kit for amateur radio. It was intended for use with a compatible Heathkit HF transceiver, which supplied the intermediate-frequency signal while the SB-500 converted signals to and from the 144 MHz amateur band. The unit is of interest to vintage-radio operators, electronics hobbyists, collectors, and restorers.
