It looks like Skipp and I have found that the GLB preselector has been
successful at helping less then ideal repeaters work better. I can
think of two examples that I have had.
I had a Midland 13-509 repeater back in the late 80's on 223.72MHz. It
used a set of homebrew copper pipe

Yes, but the NF is unpublished unknown. I therefore
assume it's poor, maybe 3 dB?
Once again, the NF depends on what device arrives in your
specific Simrex (aka GLB) Pre-Selector. It wouldn't hurt
or be impossible
Hello Bob,
I agree that the GLB is a space saving device, but don't you think that

Don't force a regular (RJ-45 type) 8-wire plug into the mike jack of a CDM
radio, unless you never plan on using the DTMF mike made for those radios.
That's because the CDM radios use a 10-wire mike jack, and the shoulders of
the 8-wire plug will deform the two outside wires in the jack that are

Hi Jack,
Hopefully you will find the Simrex / GLB Pre-selector
That is the system on my uhf repeater. It's sensitivity is unmatched with this
setup. I'm using one moto t1500 can before my arr gasfet preamp in a nema
enclosure at 100 feet on the tower. The 9db rx only antenna sits 15 feet above
that at 110 with the TX antenna 50 feet below at about 60 feet.

I have measured all the original GLB
The R100 likes to run at its rated power turning down will make it run hotter
then if you leave it at the higher power they are not a good choice for a
repeater tx.

Looking for the pinouts for the strip on the back and also can this prom be
reburned. Not much info on this unit. Ran across this controller and not
interested in spending a bunch on it. Just a cute little test controller /
backup.

Only 5 hours or so drive from me. and we could really use the equipment
down here. I'll talk with a couple of guys and see if I can find a co-pilot
or two.

Thanks for info and links:-) I see where you are coming from.. For me,
repeaters are a new deal and I am as dumb as a box of rocks, on the
subject..that's why I subscribed to the group.
My first repeater project is a portable system, so I have to make it compact
for commissioning
I didn't seen any release notes on Linkcomm's site. What's new in this release?

Hi Kev,
Yeah, I used the silver plated ones. Originally had some of the
chrome plated ones (cheap ones), but changed them out.
