Jim,

It sounds like things are OK.  Your PLL range is good.  12 kHz is an
acceptable range.
The 4 MHz oscillator is not really important except that having it on
the correct frequency just prior to a CAL PLL followed by setting all
the BFO frequencies in CAL FIL will assure you of good dial calibration.

The 4 MHz oscillator test is using the oscillator to test itself, so no
matter what the actual frequency, it will read the same plus or minus
the counter resolution, so your 3999.98 is just fine.

To set the 4 MHz oscillator "right on", wait until you have completed
the K2 and can receive a standard frequency signal like WWV.  Then check
my website www.w3fpr.com K2 Dial Calibration article.  It will explain
how to use the N6KR method to obtain accuracy without depending on the
accuracy of another instrument.

In the meantime, just set C22 to its midpoint to go through the rest of
the setup - it will be fairly close, but not optimum.
