Mechanical scanners?
Dabbling as I am with horology at the moment, I
wonder if there were any mechanical scanners, other than those which successively activated Ledex switches? What I am thinking might have been, is a pendulum or platform escapement slowly advancing a tuning condenser. |

I had a Regonda Symphony radiogram that did that, and was able to automatically stop on a station by monitoring the AGC voltage. -- Graham. %Profound_observation% |

Did you have to wind up the clockwork, or was it electrically powered? |

Actually it looks as if my Symphony didn't have the auto tune, it was its bigger brother the Rigonda Bolshoi that had it. Here is a Usenet article discussing Regonda radiogrammes in which I go all off topic and talk about 23 channel AM CB DX during 1968. https://groups.google.com/d/msg/uk.t...E/Dqoqi8rbGm4J -- Graham. %Profound_observation% |
