I had no idea what a 3450 is, until I did some Google searching and found
that you probably mean a repeater once made by E. F. Johnson. If so, a
manual is listed for sale here:

Norm,
That's really odd- the link works fine from both home and work computers.

The factory-made harness uses Delta crimped connectors, and costs about
$250. If I were to do this again, I would consider fabricating the harness
myself, with genuine Delta tees, which can be purchased for a total of
around $120.

the TX side, and desense is almost guaranteed. When properly tuned, you
should see about 1.5 dB insertion loss on both RX and TX sides, and at least
80 dB isolation on each side. I'm curious: What test equipment are you
using to tune this duplexer?
73, Eric Lemmon WB6FLY
If this is a 2m repeater, and the duplexer is mounted inside the VXR-7000
cabinet, it must be a mobile notch duplexer. I don't believe that such a
duplexer can perform with a 600 kHz split. Please elaborate on the make and
model of duplexer you have, and the RX and TX frequencies.

to the limit of its capability,
and you can test this by dropping the TX power to 15 or 20 watts, and
checking again for desense. Also, you might try temporarily swapping it for
a BpBr four cavity duplexer.

fact that only some users have the problem strongly points to the user
radios, rather than the repeater. Also, ensure that the problem radios are
exactly on frequency. Please keep this list informed as to your findings
