Broadcasting from the 20s to the 40s
Chris Walker, Loughborough Amateur Radio Club (call sign G1ETZ) comments on Frequency bands:
‘The typical bands used in early transmitting were 100 (3,000kHz), 200 (1,500kHz), 300 (1,000kHz), 500 (600kHz), 600 (500kHz) and 850 (353kHz) metres. The most common one was 200 meters, these would have been spark gap transmitters. In the mid 1920’s spark gap transmitters were prohibited from new amateur bands 80,40,20 and 5 meters.
Also amateurs found that long wave transmissions around 200 metres worked best for Transatlantic communication at that time.’
