First helo, I'm new. Please forgive my ignorance.
I came to this group from the gmrs repeater group because i'm getting
conflicting information.
I was told I must run a duplexer on my yaesu 9000 base/repeater. Then I was
told I can run 2 antennas and a combiner ? Then there was the desens.

Hey guys,
OK, I need a little help here.
Had this what seemed to be an open squelch on the repeater.
The light is on in the front of the repeater, which means the squelch is
wide open.
But yet, we couldn't hear any noise on the local receive speaker audio.
Tried turning the pot quite a few times
All I'm gonna say is buy one.

Is it wired to control the muting of the receivers local audio?
In other words, does the radios original squelch take care of the

There are a lot of opinions
It's the Icom rp4020.
When you hear local speaker audio, you hear the original squelch.
In other words, the pot on frot of the machine you could turn it all day,
and it's not gonna do squatt.
Thoughts?

If you can't find anything else to suit your fancy, look into some

has plug on modules for additional monitoring and controls and can be

Has anyone implemented a simulcast (multiple TX's on the same channel) system

of tracking within a few hertz of each other.
You can't do this with standard TCXO's, so I'm wondering if anyone has tried

Steve,
I'm experimenting with that concept on VHF, duplicating an identical
installation
in my county's public-safety UHF system. Although I am using the Kenwood
TKR-740
repeater, the county system uses Kenwood TKR-840 and Motorola MTR2000 repeaters
with Hewlett-Packard/Symmetricom
Anyone know the loss of HJ9-50 at any frequency? (yea, it's BIG stuff!)

Thanks for the quick reply. I couldn't find that anywhere on the net.
I have a guy who is telling me that 0.34 dB (at 900 MHz)
is too much loss on a SCANNER antenna run. LOL!
I'm going to ask him if I should use HJ9-50 instead. ;-
Although I have no idea how I could connect it to the antenna!

Why is that? Does the feedline start acting like an antenna (or dummy
load) when the conductors are 1/4 wavelength apart or something?

Exactly. For example 1 5/8 hardline can't be used for 2.4GHz, but
7/8 works fine.

I would first check the pin contacts in the Micor boards. Then the
