MTR-2000 repeaters are notorious for issues that require a power reset, less
often with the latest version of firmware, but still require reset, there is a
service bulletin on this.

To get the RF phase accuracy you're implying that is required would mean
that everything in the RF path would have to guarantee that phase

Optimization of a simulcast system is critical to its proper operation.
Not every local Motorola shop has the equipment or experience to perform
this activity. I have installed many simulcast systems over the years and it
always boiled down to incorrect system optimization (excluding

Anyone have, or know of, a surplus of 1/2 line? I've been scouring the
surplus places, eBay, etc., but haven't found any decent deals. I can use
pieces or reels anywhere from a few hundred to a few thousand feet. RFS,
Andrew, et. al., anything but Commscope. Thanks in advance.

Were there specific UHF MICOR components that suited themselves to Simulcasting?

Yes, but you'll probably find them most often in Micor PURC (paging)
stations. Components of interest include the high-stability and
ultra-high-stability oscillators, simulcast control card, audio delay unit
(usually made by Allen Avionics), etc. By no means a state-of-the-art
system, but they

I am wondering what one would pay for a single Doug Hall voter module in

To all,
Sorry to see that George passed away. He will be missed by all.
As were on the subject of RF amplifiers, I'm looking for someone to either
construct or sell me an amplifier in the 144 - 148 range MHz range. I'm
looking
I think notorious is an extreme exaggeration. I have eight MTR2000
repeaters in service, and they have been trouble-free. Moreover, I have
never heard of such problems from other MTR2000 owners. Some early units
had problems with a bad batch of a particular transistor, but that was
corrected
Thanks Kevin, Now I know the reason for the offset.

Kevin,
The last Doug Hall 4RV voter shelf I bought off of ebay came with a 4 ch radio
card and a 4 ch line card. I paid $250 for it a couple years ago. It was a
brand new spare that was never put in service.
Hope this helps.
