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.

You've probably got more parasitic capacitance in the circuit than that
10 pF represents. That means your capacitance range is more like 41-50
pF (figure picked out of the air) than 1-10 pF. Did the article suggest
any special construction techniques to minimize this?
