Some random thoughts:
Plug-in coils are really the way to go. But the plug-ins are rapidly
becoming unobtainium.
K5MO had a bunch of four, five, and six pin Meissner coils that he was
selling. I'm not
sure if he still has them.
One of the big concerns that Ted had was stability of the first local
oscillator. By building
a single band HBR, the three front end coils could be hard wired in. A
really cool idea
would be to pick up one of those 5-5.5 MHz Heathkit LMO's to use as the
first LO for
linearity and stability. Combining that range with the 1415 KHz IFT's
would give you
3585 KHz to 4085 KHz. I haven't considered any spurs which might be there.
If you
had the wherewithall to modify the 1415 KHz IFT's to 1500 KHz, you would
have the
entire 80m ham band.
There seem to be quite a few choices for dials other than the Eddystone.
One thought
that I have had is to use the Jackson Brother verniers with a blank CD as a
circular
dial.
One other comment. There may be another Ted Crosby out there. I have
followed
Walt Hutchens' postings over the years and have archived most of them for
ideas.
He might be the 21st Century Ted Crosby.
