Beat Note Frequency
---- A Reception Incident CHRISTCHURCH correspondent records what appeared to him to be a unique happening. The two local stations, 8YA and 3ZC were broadcasting simultaneously, the former on 806 metres (980 k.c.),"and the latter on 250 metres (1200 k.c.). Then he began to turn the dial to tune in to 2YA. . Just before reaehing 2YA mark he again heard what appeared to be a new station. The reception was clear’ but not overstrong, and the carrier wave was modulated by the transmission of 3YA and 38Z0C. The probable explanation, according to the chief engineer of the Broadcasting Company, to whom the’ incident was referred, is that the second harmonic of 8YA was causing a 760 k.c. beat with 3ZC’s fundamental of 1200. This beat note, therefore, would’ appear slightly below 2YA’s wave
