Hey Jed, You are leaving out a key piece of information. Your antennas are at
the same height and almost next to each other causing a mixing problem that I
explained to you. The problem will not go away until the antennas are
separated. You proved this by killing each transmitter separately and
actually the problem did not go away.
We tested it yesterday with UHF completely off, and 220 just kep making tons
of noise.
In fact, UHF plays fine stand alone, i had to turn 220 off when we left the

Any ideas?
I think this is more of an issue of something getting in to the input of
220.
You should be tuning the bandpass for maximum return loss, not least
insertion loss.
I've found that older Wacom duplexers develop center plunger contact
problems as they age. I trashed quite a few 900 MHz duplexers and combiner
cavities because the insertion loss was intermittantly high; the
Beyond just turning off the other repeaters, try terminating their antenna
feedlines with a dummy load instead of leaving them connected to the
equipment. See if that makes any difference.

Best I can tell the connecting harness is good. I may try the set meant for
the link radio and see what they do. How do I tune for maximum return loss?
If it is better, you can contact me off the group, so it does not get tied up.

Terry,
I understand and appreciate the fact that you are forced to employ a
makeshift procedure for duplexer alignment, since you do not have the proper
equipment (spectrum analyzer with a tracking generator, or the best choice-
vector network analyzer, aka VNA). While it is very true that one

I did find my old Icom IC-2710 dual band mobile last night. Would that be okay

I think Eric's response covered it pretty well. Lacking the right
equipment, tuning for return loss can't be done with a great deal of accury.
The closest you could get using basic instruments would be to look at
reflected power with a high-quality directional wattmeter (Bird 43) with the
cavity
Terry,
In lieu of the ideal bench equipment, yes, the IC-2710 is better than a
handheld, since its impedances are supposed to be close to 50 ohms at the
connector. You are to be commended for your creativity in making do with
what you have. Since your duplexer has been moved from its original

i have no idea what the receptacle on the power supply is used for.
Do not hook a radio to the{ receptacle on the power supply } It is used to

You can hook your radio/repeater or a fuse distribution block to the free

I suggest putting an isolator between the mobile radio duplexer (or
wattmeter, if you're measuring return loss). That will make your mobile
