K2 VCO Alignment

[Wayne Reed]

S/N 04858 is thru the 40m receiver test [Alignment and Test, Part II].  
The only problem [after replacing 10 uH L31 with 12 uH to get sufficient range of 4 MHz Osc. Cal.] was when I performed the VCO Voltage Readings.  
The voltage readings were well in range, but two bands [20 & 17 m] had frequency readings that were way out of band [20=8,757 and 17=24,254] so, after searching this wonderful archives, I performed direct frequency entry and everything fell right into place

    -and-

after that, no more funny readings.  
Well, except: BFO Low Freq. measured 4912.76 [should not read more than 4912.7] however,  I have not yet calibrated the 4 MHz Osc. as my counter needs work.
Continued right through to end of Part II and copied a QSO - FB!
Now I am ready for the last big build cycle!
I assume there will be no reprecussions from the initial funny readings.  
I have been having so much fun building the K2.

Wayne,

With only that small amount of difference, you are not likely to encounter
any problem even though your BFO low end of the range is a bit high - yes, a
60 Hz difference with an uncalibrated 4 MHz reference is 'splitting
straws' - you may want to check it later 'just for reference', but as long
as you don't run out of adjustment capability when setting the BFOs for the
filters, all is well.
