Everyone. I fixed the VFO. Its a good news/bad news thing.

Apparently my MPF102, the heart of the VFO, was either shorted out or not
working. I removed it and replaced it with another.

Good news..Cool! Now I have a good VFO in my receiver, I can hear it in my
trusty DX-398. I adjust the RF coil so its low end (with maximum
capacitance
on my Hammerland 1-10pF variable capacitor-fully meshed) is around
7.00mHz.
When I go to minimum capacitance (no meshed), I hear it only around
7.060mHz. According to specs, I should get a range from 7.00 to 7.2mHz.

Why do I not get more range? As far as I know, all caps are up to spec as
called for.
Do I need to add/subtract capacitance somewhere?

Tolerances.

Try removing a turn from the coil (if it is one you wound) and/or adding
some capacitance.
