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

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

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

You are right it could be the duplexer, but my money is still on that used

I agree. The connectors should have screwed on with your fingers. Then you
can snug them a little with pliers or a wrench.

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, s

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 open
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 wattmeter.

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 lockin
I've heard that many times right before I had to fix someone else's mess.

Thanks guys for all the answers and suggestions.
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
set of RG214 that came with the 6 cans. I also have RG214 going from the cans
