The LC-1-32S RF speech processor worked with Collins S/Line transmitters and the KWM-2 transceiver. It plugged into the first IF tube socket of the rig. The speech processor circuit used a 2N2222 transistor and had a 2.1 kHz filter. It provided about 20 dB of compression and a 5 dB increase in average power.
