Re: [Elecraft] 4 MHz oscillator is too high in frequency (K2)

Sverre Holm (LA3ZA) wrote My aging K2 (#2198) has developed a curious symptom in that the 4 MHz oscillator cannot be adjusted lower than about 4,000,000.55 kHz. This should be 550 Hz too high, that must be 4,000.55 kHz (I think!) - Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog:

Sverre, You could add additional capacity across C22 to adjust it into range - you would have to experiment with the value. The range of C22 is likely 6 to 50 pf, so adding 40 pF at a time would retain the C22 bandspread and should allow it to tune. i.e., I would suggest first putting 39 pF
