Slight correction to description. This model in the link is a 20 amp
model. Mine is listed as 15 amp.

One of you was nice enough to email me the NZ9E Audio

I can't find it and someone's asking me for it again.
Would one of you please email the article to me again?

I think I'm the guy about the filter, and the offer stands, but I agree, you need to see where in the chain it's being generated.
BTW: Since I was up there last, I took our old maggiore TX off the air, and it was similar to yours, slightest adjustment makes it a comb generator. Also, the c
David, the "Fix" for a Maggiore
repeater working in to a duplexer becoming a "comb generator"
is to put a small antenna tuner between the TX and
the duplexer.
We fixed a problem here by doing that.
The "Z" matcher that was discussed on here while
back would work as well.

Hi, I would like to know if anyone have had any luck with using a
Decibel DB411 4-bay or DB413 8-bay dipole antenna for 440 MHz service?
What is the SWR around 443? If the SWR is still below 1.5 @ 443 MHz
then I can try to order the 450-470 split antenna.

A quickie on how the maggiore squelch circuit "works". (when/if it
decides to.)
The five transistor chip is the heart of it, but not all of it.
The first transistor is just a linear amplifier.
The second is biased class C, and interacts a bit with the third.
The third is a little interesting, I

Remember the Mountain Lion stories a month or two back?
I wouldn't have believed the following story if I hadn't
seen it myself. This months story comes from the same
area as the mountain lion event...

Hi Jim thanks for the reply, Thats the way we had it Hooked up Just thought
we would see how others done it. Thanks for the input.

Well... Antennas don't create signals.
Your antenna may well be interacting with your amp in an odd way. but it's not the antenna that's making the spurs.
Can you add more feedline, so that the total length you added to the system is an even multiple of a wavelength?
