good point, I guess 13 poistions(U-13) was enough engineering for an electro -mechanical remote. Did any manual tuning sets- american or foriegn- also have UHF remote tuner function in the 70s/80s?? I guess constructing gears/mechanism was too costly or complicated for a remote 70 channel UHF tuner?
The contacts would have to be fairly sophisticated as positions for UHF channels are closer together on the channel knob. Were stepper motors ever used in TVs as these are very accurate, speed and rotation can be controlled? A continous UHF tuner would seem easier to make remote just needing two directions and stop contacts. Maybe gears needed would just be too large,too many positions for tuner to 'Clunk'.
