Beacon transmitter back view. Bottom chassis contains the ID-O-Matic keyer keying a Vectronics 1220 20-meter 1 watt transmitter. Its output feeds the transverter input. The transverter output feeds the antenna via the black coax. The coil of white coax is a shorted quarter-wave stub for harmonic suppression and DC grounding.
