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.


PS. Even clockwork toy trains had the means to engage
reverse when reaching the end of travel.

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


That's very interesting. Did you have to wind up the clockwork, or
was it electrically powered?

dc brush motor I think.
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.
