Re: [Elecraft] [K2] PLL reference test failure

Hi Don! 10pf cap seem to have fixed the problem. Thanks so much for your help! And also thanks for the information regarding J310s and J309s! Will be waiting for your testing results! 73! Ilya, R3XA 2018-08-27 14:33 GMT+03:00 Don Wilhelm : > Ilya, > > I am sorry you are having problems with th

Re: [Elecraft] [K2] PLL reference test failure

Ilya, I am sorry you are having problems with the PLL Reference Oscillator. Yes, there have been several reports of this same failure. First try a small value capacitor (10 to 15pF) from the source of Q19 to ground. If that does not correct it, can you obtain a J310 FET locally? If so, re
