Jerry:

If it still has the original selenium and filter capacitor, that is a good
place to start. Of course, the tube may be weak, although none of mine have
ever needed tubes.

Thanks, George I just made one. I wound a piece of 1/8 th
diameter
aluminum wire around a 3/8 th bolt. The leads on the coil to the meter
are
that same 1/8 th wire, about 2 inches long.
I'm impressed that the grid dipper now produces 137.50 MHz when the dial
reads 130.00. Hows that for good instructions from you??
I can tweek the frequency later, but now I see that this meter doesnt
have
alot os "power out".

The grid dipper needle doesnt get above 0.1 so the poor sensitivity is
going to make this meter difficult to interpret. I got a schematic with
this (eBay) grid dipper so I expect I'll be able to do something to get
the
meter to read a little farther up scale.

I appreciate your help.

Thanks
Jerry

Go to the jamesmillenco.com web site and scroll halfway down page 1 for
a
photo of the coils in the rack. A further Google search will reveal
many
other pages with photos. The 60 - 150 coil is two turns of #20 wire
3/8"
dia., and spaced about 1/8" apart out at the end of the plastic tube
(inside
it).

I want to make a coil for a Millen grid dip meter that I bought
*without*
coils. It would be alot easier if I had a picture of the coil Milen
uses
for the 60 to 150 MHz range. Is there anyone who'd be willing to
send
me
a
picture of that coil?

Thanks
Jerry
