Hello Walt,

"....but if you don't have the front end peaked to perfection the receiver
goes dead, so the Q is certainly high enough."

Please keep in mind that I don't know squat about building an HBR, and am
just trying to learn about the process.

>From reading the various materials that I've collected there seems to be
quite a bit of time and energy spent fiddling with each band's set of coils
to get a three bay variable capacitor to track properly, especially over a
wide band. 

Has anyone tried doing an end run around the tracking problem by having
separate capacitors for RF, LO, and Mixer, and putting up with a lot of knob
twisting in exchange?

Cheers,

Brian
