I found that the variables in the command set series of transmitters are
very close to straight line frequency. Some years ago I built a variable
osc. using one of those caps and a mechcanical digital counter and was in

within less than .5 khz over a 200khz band (160m). I of course had to do
so
I was able to get another tuning capacitor to work pretty close to the
desired 1-500KC span once on the linier dial by making the tuning capacitor
as a small part of the total capacitance of the circuit and by placing the
tuning capacitor across only a portion of the coil and the larger part of

It might be possible, by carefully pruning the coil, and adjust
Hello-
Does anyone have any information on getting a PW dial { 0 to 500 units) to
directly correspond to 0 - 500 Khz. in a VFO circuit? I have the National "PW
Condensor", a PW dial with a 155 pF. air variable. Thanks, Byron WA5THJ.
