Mike,
There is not much difference between the 10 meter and the 12 meter operation
of the K2.
Assuming that you are seeing a good peak on 10 meters, your problem is
likely connected with the bandpass filter. Check C45, the trimmers C44 and
C46, and the relay points of K6 carefully. Other than those components,
there is no difference between 10 meters and 12 meters.
Check your soldering carefully, then check it again, and if all else fails,
check the soldering - that is the most common cause of failure in the K2
kit.
If all else fails, you may want to check the VCO frequency for 12 meters -
with the dial indication at the low end of the 12 meter band, the VCO should
be producing a signal at 19975 kHz (read the frequency in CAL FCTR mode with
the counter probe in TP1). If the frequency is incorrect, the problem will
be found in the VCO area and not the BPF.
