The Elenco 77 was a 160–10 meter band-switching SSB transmitter. It had built-in VFO and VOX circuits. A crystal lattice filter was used in the sideband generator. PEP output was 100 watts. The Elenco 77 also transmitted AM and CW. The VFO covered a 200 kHz segment of each band. Full coverage of 10 meters was obtained with separate mixer crystals.
