It was around 1960 when Hallicrafters put into limited production its ahead-of-the-curve 'transistorized' FPM-200 transceiver. This was a hybridized unit with 41 transistors, 49 diodes, 14 power rectifiers and 5 tubes, and would put out 70 to 100 watts PEP SSB, 60 to 90 watts CW, and 15 to 20 watts from 80 down to 10 meters. It also featured a combination R.F. output and S-meter, CW sidetone, vox, 100KHz crystal calibrator and crystal lattice filters, a dual conversion receiver and more.
