Alliance Tenna-Rotor - RF CafeA few years ago, I posted an article about the restoration and installation of my Alliance Model U−100 Tenna−Rotor. I'm not sure of the exact vintage of my Model U-100 Tenna−Rotor, but this full-page advertisement from a 1956 issue of Radio-Electronics magazine presents the Alliance Tenn−Rotor Model U-98, so mine must be sometime after that. From what I can tell based on the ad, the controller appears to be the same or very similar. "Model U−98 - fully automatic - incorporates 32 distinct improvements - eliminates all arcing and consequent picture distortion - points directly, positively, instantly to target station - 'just set it and forget it!'" It seems they forgot to make a couple other needed improvements. As I mentioned in my article, the ker-chunk, ker-chunk of the solenoid stepping through the angle increments is a very strongly nostalgic memory from the days of yore, back at 114 River Road, in Mayo, Maryland.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
