[Elecraft] PLL reference oscillator failure

Hi everyone,

I've just got to the Alignment and Test Part 2 for my K2 and right  
off I've hit a problem.  I've got the freqency counter probe plugged  
into TP3, and I'm in Cal Fctr, but instead of the expected 12090 I'm  
getting around 400.  It wavers between 398 and 400.  The frequency  
probe works all right, when I try it on the 4 MHz crystal on the  
control board, I get a reading as expected in the Aligntment part 1.

I'll be spending more time tomorrow reviewing the PLL area but if  
anyone has some suggestions on likely culprits, advice would be most  
welcome.

Thanks & 73!
