I am about to make a tuning mod. I will add a 27-50 ohm resistor in series to each side of the tuning pot (yellow and green) That will prevent the pot from fast tuning at either end of travel. I will add 2 momentary buttons from the pot. One violet to yellow, the other violet to green. If my understanding of the tuning method is correct, this will exclude the control from doing anything but changing frequency in its normal range. When I want to step up, just push the U button, down press the D button, essentially having a sort of band range control over the desired frequency. I also plan on using a 10 turn, or a 3 turn 10k linear pot. Obviously using a multi turn pot makes the button mod a real necessity. No more getting close to the end of pot tuning travel then "ooops' the frequency starts taking off. Thoughts?
