I've got one, and I wouldn't give you a nickel for them! They are NOT a
PI network for matching. They are a T network! The input goes into the
variable cap on the left, the inductor takes the end of that cap and
works its inductance to ground, and then the end of the first cap that
is tied
then re-wire it.

Rob - If it had decent stand-off insulators, I would!
They used acrylic in a couple of places, but no ceramic or decent
insulators anywhere!
I'd have to gut it, install ceramic stand-offs, hope everything clears
the cabinet and the top cover, then see if it WILL work right.
There is going to
Everybody wants to re-wire it.
Try this link to my site to see the schemetic of this thing.

Then explain how one *might* re-wire it - AND - put in place adequate
insulation!
(Inside the same cabinet, I might add!)

The Murch UT-2000A is a commercial version of the classic Ultimate
Transmatch designed by Lew McCoy and featured in the July 1970 issue of
QST and numerous ARRL handbooks.It's called ultimate because it is
able to match coaxial-fed antennas, end-fed wires, and with the addition
of a 4:1
I don't care if Marconi himself designed it.
It will NOT tune a BC-610 to ANY antenna!
Even after setting the BC-610 to the 400W ME-165G 50 ohm dummy load
first. It would melt the final before it managed to match anything.
250THs don't grow on trees!
I have the manual. I have checked it
Bob,
I don't dump a rig full power into a tuner and start adjusting it. I
don't own a 610 but I agree that would not be good for the 610. I
have never owned one of those Murch tuners (I remember the original
QST article though) so it may be true that the Murch won't handle the
full output of
I am not famiiar with the BC 610 output circuit however it may be link coupled
and 600 ohm or other high impedence as most of the transmitters in the late
30's and 40's. The Murch is designed to match an antenna to a 50 to 75 ohm
load. Therefore you may be exceeding what the Murch is capable of
if you hate it that bad take it out back and shoot it .
