Well, I made some measurements tonite. Using the k2 counter to track the BFO and an external counter to track the PLL, I measured from cold start to 45 minutes, with no transmitting. The results: PLL drifted 50hz UP, and the BFO drifted 60 hz DOWN. Perfect for the higher bands where they almost cancel, but not so for the lower bands where they add (do I have that right?). Does anyone have any info on frequency compensating the oscillators using negative coefficient caps?
