Let's not start that again...---If it's Cook Towers, I don't think we want to hearabout it!By the way, did that issue ever get resolved properly,or did it just fade away, finally!?!?!?
I thank you for the response .I don't usually set the TX cable at one length andit varies at all my sites .most of the sites may be around aprox 1 meteror so
Thank You,

I keep hearing about these "Z-Matchers". Who makes them, and are they expensive?

Hi David
Thanks for the offer but the TK-722 is a totally different radio.
It is a mobile radio and the TKB-720 radio I am looking for a controller
for is a
Base station radio. It is about 6 inches high 15 inches deep and 14
inches wide and weighs
About 30 pounds because in includes a AC power

A while back there was an excellent

Well, it was worth a try.
The RF Deck came out of a TKR 620 desk-top repeater. Unfortunately, the
front panel and other items were lost when the owner scrapped it out for
the power supply present in the Desk-Top repeater that the TK-722R came
out of; as well as the boards I described.

I bought these cans at Dayton last year. I have no

I am about 99 percent sure those are Sinclair cavities that belong on a hybrid ring duplexer. And if so, there should be a loop harness and the "stub" should not be attached to the Tee connector. Do a search on Hybrid ring and you should find the info. If not, look on Skipp's repeater
Scott, those sure look like Sinclair to

Can you recall where you saw the article and/or did you keep notes of
the component values for the VHF and UHF caps, coils, etc. Would
like to duplicate you efforts if possible. Thanks

Looks like the stub was absonded from a set of Wacom cavities in an attempt to make the cavity into a BpBr type.On 1/24/06, Steve Kometz

to me it looks like my sinclare hybrid ring duplexer but I could be

Has anyone used any wx stations such as the talking ones from best
buy, oregon scientific , etc and interfaced them with their
controller ?
I thought since they speak temp/wind speed etc. it could be done, just
wondered if anyone has tried it and what worked best if you have.

Will, there are a lot of repeater
controllers available that will do the linking tasks.
Hams generally do their linking over
the air with low power radios on a dedicated
linking frequency.
However, you can use your leased line
and send the linking stuff over it.

Of course, usually the systems feeding such a combiner have TX cavities
on them of some sort... not always, though.
These definetly are from a Sinclair hybird-ring duplexer. The coaxial

ring phasing harness. I believe these are single mode cavities. I have

Is that commonly called hybrid ring technology? I think Sinclair made a
duplexer that used that technology, is that correct?
