[Boatanchors] Miller 4-band coil

[Jim Wiley]

Well, here's a true shot in the dark.  I am looking for specs, perhaps 
even an example (read, I want one) of a rather unique coil made by the 
J.W. Miller company in the 60's and early 70's.  It had 4 sets of 
windings, and when used with a 365 pf tuning capacitor, tuned from BC 
band thru 30 MHz, or so.   There were 2 windings for each band,  which 
could be used as a main coil and a tickler, for a regen receiver.  I 
believe it could also be used as the input coil between the antenna and 
a mixer stage and even (with the appropriate padding caps) as the 
oscillator coil for a superhet.    Two or three of these units could 
form the basis for the front end of a band-switching  general coverage 
receiver.


The coil was on the order of 5 inches long, about 1 inch in diameter 
(dimensions are approximate and from my memory).    


Each coil "set" had a common connection for one end of a group of coils, 
and individual connections for the "hot" end.  IN other words, all the 
"main" windings had a common termination for all 4 coils, and all of the 
"tickler" windings had one common termination for the "cold" end of each 
coil in the set.  That means for each group, there were 5 terminals, one 
common and 4 separate lugs, one for each coil.  Terminations were small 
solder lugs, and the coil mounted on a pair of metal "L" brackets. 


Has anyone seen such a beast., or perhaps has an old Miller catalog, 
that could result in a part number, or some information on specs (turns, 
diameter, and so on).  Does anyone perhaps have such a beast they would 
be willing to part with, either for cash or trade?  Could someone email 
a scan of the appropriate catalog page?


This coil was used in an construction project from either Popular 
Electronics or "Radio / TV Experimenter" magazine of the era, and I 
would like to see a scan of the article, if possible.  The coil may have 
even been built for that particular article, but that would be a bit of 
a stretch.


OK, guys and gals, you have your assignment.  Let's see what you can 
come up with.
