Problems with Alignment & test Part II

Dave-282
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?
