Very interesting...all our sites are dense with RF from Public Safety radio
systems 800, 700, VHF, etc. No problems in five years. I suspect it has
more to do with how the RF connections are made than the LMR cable. Just my
subjective opinion of one.
Actually it is the cable. My discussion
Any reasons?
First, it could be used as a duplexer, however you don't get all the benefit
you would get from a BpBr duplexer.
The one in question is a notch only duplexer, the cavities are designed to
notch the two frequencies in use. While it can work, you generally cannot
get the required
More fun is to find the actual frequency.and leave your service monitor in
the generate mode on that one for a bit, should be fun :-)

Uh oh, here we go again. There is a perceived risk of noise due to the

You can always mount it upside down, works quite well generally.
As it sits, it would have quite a bit of UPtilt on the 400 frequencies.
That's not good unless your repeater is in a valley.

In a perfect world you would be correct. But unforunately amateur
radio coordination is far from perfect.
Regarding some of the systems that the ORRC believe are uncoordinated which
I am affilated, that is because they do not recognize the 2 other

It is a fact the NFCC recognition/certification means zero in the eyes of
the FCC. What matters is recognition by the local constituency.
I'm curious and would enjoy the documentation you have that shows that
statement to be factual.
I can understand that if there is a legal conflict between

There is no reason why other coordination groups need to jump thru the

In this case it does say that you can't run a simplex or

Where is this again? I’m just not finding all these rules you folks are saying

We tried a variety of off the shelf receivers, the WX-100 doesn't go off on
tests so that was worthless. We tried a couple others and finally spend the
money on the Cat WX-200 and just standardized on that. It does real well,
it's a bit more spendy, but it does a regular drop and insert

I can't imagine why you would want to put a window filter
between your duplexer and antenna line. There is much more
to be gained by putting separate band pass filters on the
tx and rx ports.
There can be good reasons for including a window filter with
a duplexer. Reduction of high

If there are any 150 MHz analog paging systems around, try listening to
them.

We had some discussion on another list regarding the legality of
'automatically' rebroadcasting NWS data on an amateur repeater. The rules
clearly allow for rebroadcasting the weather information, but are not clear
on how that can be done. One repeater owner on the list send an email to

I think the concern is that of many
trickle charge systems. They are designed to float the batteries and switch
over if needed. They are NOT designed to recharge a depleted battery bank.
All this is fine unless you lose power on the site for 48 hours and run your
batteries flat and then
