[Elecraft] K2 PLL reference oscillator range test

Another question:

I just started running through the Part II assembly tests and alignments. 
I couldn't do the 4 MHz oscillator calibration because I don't have my
external frequency counter on hand.  I then went on to the PLL reference
oscillator range test and got a range value of 13.8 kHz.  The value
should be between 9.8 and 13 according to the manual.  Is a value of 13.8 
going to be problematic?  Could I be getting an artificially high value
because I have not yet trimmed C22 as part of the 4 MHz oscillator
calibration?  I am going to recheck all of the joints in the PLL circuit now.

Happy field day!
