Hello, I have the same problem, on the vfo I can see how I go up and down in frequency, but the real change is every khz, I have measured the impulses in (P07 FROM PIN 1 TO PIN8) with an oscilloscope, and I can see the impulses, increasingly wider as I go up from pin to pin 8 (P06 FROM PIN 9 TO PIN 17) on pin 17 I can still see from time to time how the impulse rises. Luckily I have 2 vfo boards, but both have the same symptom, it is difficult to have the same failure on 2 different boards. any ideas?
