Is D3 oriented correctly? Is it well soldered?
Is C2 well soldered?
Those two components are about the only ones that would prevent the
frequency from changing.
A faulty D3 is a possibility, although that would be rare.

I'm at the VFO range test in building of my K1. I go into the CAL menu,
display OSC and see a freq of 3.121 MHz. The frequency does not change when
I turn the VFO tuning pot.
I checked the voltage on the VFO POT signal and it goes between 0v and
5.935v. The voltage on D3 goes between 0v and 5.888v.
Any suggestions on where I should look to determine why I cannot change VFO
frequency ?
