Thanks Oz for the comments.
You are right it could be the duplexer, but my money is still on that used
antenna.
I know when I moved the duplexer to here, I had it wrapped in a blanket and
strapped in to the car seat like a baby.
I found a document on hooking a handheld to the transmit side

In your initial post ypu mentioned that you had to use pliers to
tighten the connectors on both ends.
2 possibilities:
1) You used the wrong connectors.
Yes I have seen this done before. A PL259 screwed onto a N-Female.
Contact made but poor range on a simplex system; looked OK on
John, you said it. There always seems to be someone who thinks all you need to
be a tech is a bench full of equipment. On another group I saw a post from
someone who was going to 'modify' his handheld ( SDR radio with all SMT ), had
all the equipment, just wanted to know how to get the case

I will try most of them, probably not the isolator until we can find one.
The interconnecting cables for the duplexer are from Wacom and are a matched

Thanks for the latest batch of advice.
I did find one thing this morning, this first can on the transmit side was not
locked down. So this could be a problem as well.
The connectors are really tight to turn, so that is why the pliers have to be
used. Again one of the club member made them up,
recommend it.

We did discover that the receive works great when the transmitter is attached
to another antenna.
Receive strength went way up. But, of course that doesn't fix the problem of
wanting to use only one antenna.
So for now, the receive will be on the repeater antenna and the transmit on a

Correct Andy,
As they say I might have won the battle but the war is not over.
I still need to come up with the why it is happening. Then the solution.
My next attempt is to take the bandpass out of line and try it just

There's a great document on the RB website that discusses desense. If you

Hi,
First thing. Remove the preamp. Those things are only useful after you have
a tight working system.
I've heard that many times right before I had to fix someone else's mess.

John,
Some comments and observations;
Moving a 30 or 40 year old might radio invalidate the fact that it was
working at the other site.
Duplexers, particularly 'vintage' duplexers don't always travel well.
This is particularly true when the person doing the alignment forgets to
run the locking
