On the sets I have I had to add about 2 1/2" of copper brasing rod to the rod
that is in the center of the tunning capacitor.
Also if you have PL-259s on the cans the "Tees" like to go bad, I had one
disintegrate in my hand once.
If you have "N" connectors, the solder joints from the connect

Oh, Okay. I have about 6 sets of these and yes they are a great UHF
duplexer.

I have used VHF cavities in 3/4 mode many times for UHF combining - Cabling
would not be the same, but the 10" Sinclairs I use for a 5 channel UHF
combiner work well.

What do you think about putting a Kenwood tk750 and a WP639 90 ft below
a 50KW channel 6 TV transmitter, soon to have hdtv added on the side, on
a tower with a cage life and cables that chaff when the wind blows at
1750 feet above ground with #12 power service (120VAC) shared with an

Actually, the specifications listed in Wacom's original documentation
**for this duplexer** is *AT* 600 Kc. :

I'm not sure that those "smaller" cans are good at 600Kc?? Or if they are, then
you may have the wrong interconnecting cables on them.

The
tuning for the WP-642 is the same as the 641, but you'll have to
tune the additional 2 cavities on the radio side; which are simply

Yes it is interesting.
How did you manage to tune up a set of 2 mete
Indeed, everyone has made a good point (or more) in this thread. I agree
with Kevin, GE's MASTR II PLL VHF Exciter, or a tube set on any band, are
certainly better. There's a high-performance UHF system that I'm involved
with utilizing a B94MSY (1/4KW tube PA) with only a PD526 duplexer and

I couldn't get these cans to work with my repeater, I ran out of room

any further... Anyone else have experiance with these cans, are they
any good??
