Hi all,
We are currently applying for a 7.6Mhz split UHF repeater here which
means we will be able to do away with the old and lossy large cavity

promising wit
I'm afraid you've missed the ARRL's point. It's not about what modes are

VHF/UHF repeater input to 10M does not constitute a remote b
Hi everyone!
I just installed an Icom IC-706MKIIG in my UHF repeater for use as a
remote base. I did this to consolidate, and to replace 3 other aging
remote radios.
The method which I use to activate/deactivate the IC-706 actually
switches DC power to the radio on & off. So here's my question
When I moved some 155 mhz duplexers to 146 I found adding a type n elbow
in places where I could not get the notch to move made just enough

To recommend what to do, the first thing is to
determine which type of Q202G duplexer you have. Here
is the manual on an older type that has the variable

If you use 7/8" hardline for the feedline you will need to use 2 jumpers at
either end for your connections. This will add a minimum of 4 more connectors
to the overall feedline, introducing more loss. More importantly, this will
add more points of possible failures. I would use 1/2" hardline

Thanks to all who have replied. You have been a great help.

That's nice, but the ARRL does not make the rules, and I can find
nothing in Part 97 about AUX frequencies being limited to a single user.
There is a saying about opinions and how everyone has one. The ARRL is

Eric,
Being the cheap hams that we are (I am at least), couldn't you just
get 5 Tees for a couple bucks a piece and have your favorite two-way
shop make up four 12.5 inch cables from RG-214 for about $15 each?
Total around $75.
I've had cables made in our area for about that price. Obviously,
Steve,
That trick works fine for offsetting the harness tee from the loop assembly
in the can, but it doesn't do a thing for increasing the spacing between the
tees. The later-design Sinclair Q202-G duplexers come with a one-piece
harness that is made up from sections of RG-214/U cable with five
It's not the 10M radio that is in AUX operation - it's the (2M or
higher) frequencies that are dhared by the repeater that are. The
statement was that *those* cannot be AUX frequencies since they have
multiple users. (a stand that is completely ridiculous)
I wonder if this has something to do with
Bill,
I measured the new low-split Sinclair harness before installing it, and
found that the distance between the centers of the tees was exactly 14".
The length of the loop inside the cavity is about 8.5", and this length must
be considered when performing the calculations. My guess is that a di

Dwayne,
You make a good point. Like Bill, I would be reluctant to fork over more
than $300 for a cable harness from Sinclair.
However, I don't think you can duplicate the Sinclair harness for $75. If I
were to make up such a harness myself, I would not use sections of RG-214

Hi Nate-
You are correct, you don't know the situation. There are plenty of systems
that provide good metro coverage with 1 or maybe 2 repeaters here in
Portland.

2. Most likely solution. OR, have them help out existing repeater

usually maintained by one person. Also, define 'shared'. It's not
