Bill,
That is not a good situation, and I have never seen that condition.
Check the orientation of varactors D37 and D38.
Then check the soldering of the L33 leads to the 1/8 watt resistor - you
may have to use a magnifier and good lighting.
Then check the soldering of all components. To find out which
components, look at the right corner of the RF Board schematic sheet 2.
All the components shown below U11 are suspect.

A question if you please.
I am assembling a K-2. At present, I am currently in the Alignment and
Test section, Part II. Page 65 covers the BFO test where you use Band+
and Band- to check for BFO range. When I press Band+, the frequency
counter initially reads around 1.480 MHz and starts increasing in
frequency. I am guessing about 100 kHz per minute. When I press Band-,
I get a good reading of 4.911 MHz. All of the other checks thusfar in
this Part II have been good. This is puzzling and I hope someone can
give me some ideas.
