[Elecraft] Elecraft K2 7855, alignment and test part II, bad PLL frequency.

[Christophe GIBERT]

Hi! First of all, sorry for my poor english, i’m french ;-)

I’m building my k2 number 7855. 

In the first step of the 4mhz oscillator calibration, i get a frequency of 00500.00 instead of 12090.00 

When i press BAND + : 00475.00 and BAND - : 12085.43 (stable).

I’ve tested probe on TP2, I’d 4913.52

I reviewed all components in the pll schematics and nothing seems wrong. 

Please help me, i don’t know what to look for now.

Thanks a lot.
