I’m just getting around to reading this issue. It somehow ended up at the bottom of a pile of stuff.
Inside is a reprint of an article entitled Radio Teletype from the December 1951 issue, written by Wayne Green, W2NSD. It was Wayne’s first CQ article.
It was fun to read about how it all started, who the early contributors were (John Willians, W2BFD is mentioned) and what it was like back then.
I learned that at the time the active stations were on 2 meters (147.96 megahertz was the standard channel). 40 Meters had not been opened yet for RTTY. Hams had to build their own selective audio amplifier and frequency shift audio oscillator.There was a circuit diagram, instructions and a drilling template to build a panel for the circuit available from John Williams. The teletype of the day for ham use was the Model 12. John’s circuit would wake up every hour and listen for one minute for any traffic. If there was traffic it would turn on the teletype and copy the traffic. If no traffic (or after the traffic ended), it would turn off the teletype after one minute of listening.
