come in 2 varieties- a LOW freq head (freq range unknown), and a HF-VHF
version 2.2 MHz to 400 MHz in 7 ranges, and have a 4 inch meter (great
for these fadeing eyes) But- make sure that these have all their coils, and
tuneing
head! Tuneing is quite smooth and freq is acurate - modification article
for them
is in vintage Ham Radio issue. Agree with george- selenium is probably
shot, as well
as filter cap., and tube probably getting quite old (glow violet?- its
"gassy", and migh
salvage it by keeping power on it for couple weeks, but cheap to replace)!
Good luck, either way! Jim NN7K

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

There was a decent looking Measurements Grid Dipper on eBay a few weeks
ago and I thought I'd win it when I placed a $ 75.00 bid. But when I got
outbid, I assumed that there was a rich market for the Measuurement-Boonton
meters, so I lowered my sights and got this Millen (minus coils) for $16.00.
I think this Millen will be fun to make work and I'm actually happy with it
now that George has shown me how to make the coil for the one frequency I'm
interested in.
The Millen has a jack that allows the user to include a meter in series
with the Millen meter. I plugged a 250 Microamp (FS) ammeter and think the
meter is OK for my use now.
The more I learn about Grid Dip Meters, the more respect I have for them.

Thanks for all the help and advice.

meters , were made in Boontown, N.J.)

Actually, it's Boonton, N.J., I've been to the
Measurements Corp factory. There was
another company there that used the name
"Boonton". I have one of their RF Voltmeters.

...These
come in 2 varieties- a LOW freq head (freq range unknown), and a HF-VHF
version 2.2 MHz to 400 MHz ...

One meter/power supply unit, three tuning
heads. Mine are packed at the moment,
but the LF head covers roughly 60 kHz to
2.3 MHz, the most common head covers
2.2 to 400 MHz, and the UHF head covers
up to about 1GHz, as I recall.

I have all three heads, and use them all.
Great instrument, but many newcomers
(even a Hewlett-Packard RF engineer I
once worked for) have never seen one.

Yeh, and my first experience with one was at a Ham, and now long retired
Tektronix employee. always wanted one-- bought mine for around 60 bux!
The interesting thing was , found 2 of them (SANS OSCILLATOR HEAD) for
10 bux, and one of them NOT the WW II version, but in a SQUARE, modern
houseing ! Probably should have got them on spot, but then there is
always next year!! Not much call, unfortunatly for great test lab
quality equipment (too many appliance ops!) but then the more they DONT
recognize this stuff, the cheaper it is for me!! Good Memories- from
around 35 years ago! Jim NN7K
