Mike, I think the next step would be to try to get the paging operator to
install an isolator on the output of his VHF pager for a temporary check. If
he has one already, he could try putting two in tandem to increase the
rejection of any RF coming back down the feedline from his antenna.
If I have followed the thread correctly, this interference happens from
either of the paging transmitters, not just one or the other.
I would suggest you check to see if there is a TV linear translator very nearby
it could be the source.

I just found two more Icoms with sockets. 4EG25A10 on 455.85 and 455.45

Re: Helical or Hybrid Ring Duplexer for 6M
I'm working on a theoretical design, but I need 5 Circulators.

A 1 rack unit duplexer for a 30-50MHz low band system is impractical
vs 4 6-8 foot tall 12 cavities?

Hi Cruizzer
I build a 6m repeater 10 years ago, 2 yrs on air, till lightning bolt toasted
it.
First tried spilt antennas. Lousy performance.
Tried adding coax 1/4 wave stubs, but were too broad.
Then built 6 cavity hybird ring helical in paint can duplexer. Worked, but
tuning drifted due
