Doug,
Are you on 40 meters?
Did you measure the PLL Reference oscillator range (counter probe in
TP3)? What were the frequencies?
Any chance you replaced Q19 during the upgrade process? If so, where
did you get it?

What were the results of the PLL Reference Oscillator test - especially
the high frequency at TP3? - the frequencies please.
The 5 volts on the SCK signal is normal.
Do not wear out the slug in L30!
Is this a new build or the result of upgrades to an old K2?
Do you have an oscilloscope with a
I am suffering from a similar problem in the midst of applying the various
upgrades. My BFO test numbers are good,
4917.13 kHz
4912.16 kHz
4.97 kHz range
but when I try the VCO linearization process, I see 11090 flash and then get
error 232. I have not checked the VFO against a reference
Issue. Unable to undertake VCO alignment. Voltage at R30 fixed at 24mV.
The VCO oscillator test (Alignment and test Part II p 63) has passed. Well
the frequency is 7.98MHz rather than 8->10 but that conceivably could be
within the bounds of measurement error.
In the VCO alignment test a DMM
