Model TCS Equipment Keying Tests

Abstract

Tests have been made to determine the effect on clipping of individual relay characteristics, primary supply voltage variation, crystal characteristics, multiple band operation, and oscillator circuit characteristics, in the Model TCS transmitters. The relays were found to be causing a major part of the clipping when the transmitter is performing acceptable, and some improvement is considered possible. A minor modification of the crystal oscillator circuit did not result in less clipping due to oscillator lag.
