We have one in place right now on the 600 KHz split at 25 watts from a
MastrII...
Very noticeable desense...
Not very happy with the setup... But we're doing the best we can with what
was on the hill when we started...
Oh well lol.

The Q2330E has three cavities on each side.

it for minimum VSWR...that should clean it up
GE did this with a device they called a Z Matcher.

Any suggestions for improving the situation with our existing Q2220E
duplexer?
We could turn the P/A down even further, but there's not much more room to
work with with this 40 watt P/A from it's current

Actually, the comment below isn't quite true.
The Q2220E is a Res-Lok duplexer, but there are no machined coupling ports
between the cavities. I just took the loops out of one to confirm.
The coupling between the cavities is a function of the pickup loop inside the
cavity, and the coax between
Yes, but we modified/replaced the loops in the cavities to get better
performance. No changes were made to the harness as I recall. I don't recall
