Thanks Guys,
I've got some surplus equipment, but nothing has been calibrated in years. I have a Lodestar Signal Generator/Counter, an HP 5315B Universal counter, and a Tektronics 465B Dual Trace scope. All I can say is that the Lodestar and the Hewlett Packard agree within decimals, so I have to assume that the generated frequency is pretty close. With the last re-alignment, I ended up with the lower end of the band indicating "dead on" but the upper end off about 40 Khz. I end up using the pushbuttons, exclusively, so in reality, the whole thing is just an annoyance.

I'm thinking that, at this juncture, with my limited understanding of how the circuits work, and precisely how to affect a solution, I'm probably going to have to live with what I've got.
