I have posted a copy of the QST ad on my website.https://www.w7ekb.com/glowbugs/tx/813osc/813osc.htmRCA published a more detailed article on that single-813 power oscillator in an issue of their Ham Tips in 1938, a copy of which is also posted on my web site.Lastly, one of my early Elmers, Walt Polete W7JIZ built and operated one. He demonstrated it to me and another Elmer, Woody Davey W7CJB, sometime around 1956 in Missoula, Montana.Lastly, Jack Meadows W7QQQ recently built one and I have worked him on the air.Ken W7EKBSent via the Samsung Galaxy S21 5G, an AT&T 5G smartphone-------- Original message --------From: Hubert Miller <Kargo_cult at msn.com> Date: 1/7/26  18:23  (GMT-08:00) To: milsurplus at mailman.qth.net Subject: Re: [Milsurplus] Hey Bob, W9RAN I would like to retain the single - tube nature of the Conar transmitter. This has certain bragging rights. If it means i must use old - stock FT-243s, so be it. I will be carefull. This topic has me wondering about a tube company ad on the back of a CQ magazine. It showed a single 813 tube "power oscillator". No - not a MOPA; just one tube. How did they do that, i wondered. Without immediately cracking the crystal.I recall many decades ago in high school, i was taking some kind of electronics class. There was some breadboard circuitprototyping kit and i had from somewhere, a crystal for the AM broadcast band. I built up a single tube, something like6DQ6 tube, power oscillator transmitter. How long did that last ? About long enough to send one line of text CW; thenthe crystal, no more work. -Hue Miller ______________________________________________________________Milsurplus mailing listHome: http://mailman.qth.net/mailman/listinfo/milsurplusHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Milsurplus at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html
