Sorry, I forgot to specify it is a K2 (you probably figured that one
out yourselves) and I did intall the Noise Blanker but it was removed
and jumpered for the tests.

Greetings,
To recap, I have a bar or so of S meter, regardless of band, and the
cw signals are there, but not loud, crisp and prominent as on my K1
tuned to the same freq.
I built the crystal oscillator for signal tracing with a 30 meter
crystal, and it is powered by 12v.

Things seem to go wrong kinda where I expected, in the mixer, i.f. amp
and crystal filter.  Here are my findings.
Appendix E Troubleshooting, Page 10

PLL Reference Oscillator and VCO
Step 2: Reference oscillator output. Expected: .8-1.8, Actual: 1.155
Step 3: VCO output. Expected: .3-.4 Actual: .342
Step 4: VCO Buffer Output: Expected: .6-.75 Actual: .646

BFO (Page 11)
BFO Output. Expected .2-.7 Actual: .625
BFO Buffer Output. Expected .025-.070 Actual: .046

Low pass filter, bandpass filterand T-R switch
Step 9: Low-pass filter output. Expected: .13 Actual: .12
Step 10: T-R switch #1 output. Expected: .093 Actual: .086
Step 11: Band pass filter output. Expected: .086 Actual: .079
Step 12: T-R swtich #2 output. Expected: .077 Actual: .066

Mixer, I.F. amplifiers and crystal filter
****** I am assuming that the next two tests were done no ATTEN and no
PRE selected ******
Step 1: Attenuator off test. Expected: .077 Actual: .067
Step 2: Preamp off test. Expected: .077 Actual: .066
Step 3: Composite Mixer output. Expected: .079 Actual: .059
***** Here is where things start to go bad. *******
Step 4: Post mixer amp output. Expected: 2.20 Actual: 3.956
Step 5: -5 dB pad output. Expected: 1.4 Actual: 3.983
Step 6: Crystal filter output. Expected: .35 Actual: .128
Step 7: T7 Step up ratio. Expected: .4-.8 Actual: .46
Step 8: I.F. amp saturated output:  I measured 0v, I could not get .15
by cranking up the signal generator.
At this point I stopped as prior results need to be fixed before pressing on.

During the build, I grabbed Q12, 2N7000, and soldered it elsewhere by
mistake. I removed it and resoldered it correctly when I discovered my
mistake, no power had been applied with the component in the incorrect
spot. Maybe I blew it up???
Below are DC readings from page 17, RF board.

Q12 Source. Expected: 0 Actual: .114
Q12 Gate. Expected: 6 Actual: 6.05
Q12 Drain. Expected: 0 Actual: 0

Q22 Emitter. Expected: 1.3 Actual: 1.2
Q22 Base. Expected: 2.0 Actual: 1.9
Q22 Collector. Expected: 12.5 Actual: 11.19

U12, all voltages were very close, expected 7.9 was 7.75

The rig was supplied with 12.33 (gel cell)
Sorry aobut the long message, but will appreciate any thoughts. And or prayers.
