[Elecraft] PLL es BFO range test

[Dave]

I didn't get much of a response to my first request of help so I thought I'd
try again.

I have spent most of the day checking and re-checking and am not making any
headway.

 

 

I am building a K2 and everything has been going fine until the "PLL
Reference Oscillator Range test". Pressing the Band+ switch does not change
the PLL reference display (12113). The Band- switch changes the reference
display to 12067. Pressing the Band + switch again displays the PLL
reference freq. of 12113. 

 

I looked for bad solder connections, incorrect or missing components and
could not find any. 

 

Pressing on with the alignment process I found that the "BFO range test"

gave similar results. In this case neither the band+ nor the band- displayed
the BFO range. The display stayed at 4912 khz. 

 

Any Ideas?
