The radios used in the early '60's weren't ''digital proportional'', so what were they like to operate?
If you gave them some hrow, or input, did they go all the way? Was there any variation in the amount of throw they gave?
racerchuck,
There were also for a short period analog proportional systems, older than digital proportional.
They did operate by changing a few audio frequencies for main control functions sometimes combined with pulse length for other channels.
The analog audio frequenciy"modulated" proportional channels have to operate the same way the later digital pulse-length "modulated" proportional channel is working.
That's why we also call these "proportional" radio.
A profit maybe is, the audio "modulated" channels are kind of fail-safe.
Modulated between two "" because all systems that time were AM (amplitude modulated).
Could buy me 6 "potkernen" yesterday, diameter 14 mm, to build me a new 6 channel (blip/blip, tip/tip) receiver to combine with my old tone modulated transmitter, I also can make 3 channels analog proportional with these elements after winding the coils but for that I also have to make a transmitter in that "case".
