How Radio Works

Well, to temporarily re-rail this thread... thanks for the post. I really enjoy watching this stuff-- although without the film breaking or slipping at least once, it's not the same. :)

Interesting, considering the "sponsor" of the film, that among the views of different microphones was one marked "NBC"! I'll bet there was nary a Ford in this clip though!

The best thing about the posting, though, was that it led me to find this one (not radio related):

(Yes, I AM having a flashback... it's "Our Mr. Sun"!)

And now, back to our discussion of coin-operated transmitters...
 
The Moseley TRC-15 was a very common system dating to the 1970s. My favorite was the Gates remote control system from the 1950s that had plug-in subchassis, each function having its own tube-type tone oscillator....a different frequency each for raise, lower, on, off. The tubes would age and the frequencies would drift. You couldn't get the transmitter to respond. It would come on the air, but then you couldn't turn it off. Or you could reduce power but not turn it back up.

One station where I worked which will remain nameless, finally said "screw it" with the CE installing a chicken timer up at the transmitter site. About a half-hour before sign-on, KLUNK! The filaments would magically light without any human input whatsoever! Illegal as hell....but it saved money.....
 
I work the same remote control at Crawford as scooter does. Checking the tower lights at night is a hoot as well. :)
