Eric,
I agree.. "on the money" usually equates to the maximum performace for your
intended application. Unfortunately the result is not always within the
designed parameters of the cavity and performance from design specs suffers
slightly.
But if it suits your needs and performance is acceptable,
I
wasn't trying to bash you.. just pointing out that it wasn't a very
positive tactic..
Anyway, I hope your connectivity issue has been resolved. And yes,
there is a wealth of knowledge in this group. Normally I don't post
much.. but your comment just struck me as odd..

Hi Guys and Girls.
Is there a location where I can get more info on the theory of collinear
antenna's.
They are used allot here in OZ at least over the past 30+ years that I have
been in the game.
I have read info on phasing multiple dipoles.

Please elaborate on the exact nature of the interference. Is the issue one
of the tower receiving your signal, or the planes, or both? Have you gone

Ken,
I think the "stock answer" is the one to follow. Actually, since the
bandpass tuning on a typical BpBr duplexer is rather broad, while the notch
tuning is very sharp, better results might be achieved by tuning the center
(bandpass) rod so that the notch is where you want it, rather than look

The notch "generally" will track the pass as it's adjusted, but it's not a
fixed-offset kind of thing. If you retune one of the cavities +1 MHz, the
notch may move +1.1 MHz, or +0.9 MHz, or ...you get the idea. So, no, you
can't just re-tune the pass and assume the notch has followed exactly.
Hi folks
I know the "stock" answer, but I'm looking for the non-stock one :-) (and
yes, I've read the manual!).
But I was wondering (and checking my rationale here). in many Bp/Br
cavities, the notch tuning actually tunes to a certain freq above or below
the pass-tuned frequency. Therefore, i

so, check to see if any event (lightning, a new station startup, etc.)

Open it up and see if you put the new battery back in
wrong. If it's not a Kenwood original the after market
stuff is sometimes backwards in polarity.
The owners manual has the cpu reset ... otherwise you

Hi
My 2 cents worth
Are you using a PL code which is harmonically related to the AC line freq?
i.e. 123.0 or 179.9 ?
An earlier respondent suggested changing the PL and I concur with this as
a good test.

An antenna that is built for a higher frequency than what you are
