How to set up a GMRS repeater

[Grizzler]

Hey guys, first post, first question. 

I live in the middle of a large patch of the Mark Twain National Forest with several trails and trailheads. I run CB, Ham, and GMRS. I am interested in setting up a GMRS repeater for hikers and for personal use.  I have a Rohn 25G 37' tower 73 mile Horizon/ 41 mile LOS . What do I need to get a repeater up and running?

The basic items you need are:

A good antenna

Feed line & grounding

Repeater, look up surplus Motorola Quantar, though you will have to likely turn them down to 50w

Power

 

I suggest reading this thread:

See the thread above. While you can put up a cheap repeater if you want one that will get used and works well you need to spend some coin. Lots of info in the link above.

I highly recommend the Bridgecom repeater. It comes fully tuned and programmed to your specs. Put up a DB-404 antenna on that tower, some half-inch heliax and you will be ready to go on the air.

I just finished a 'home brew" 50W repeater for about $790 not counting the antenna/duplexer, etc..  Very simple to put together and set up.. of course, for more $ you can do something much fancier, but it wont transmit any further.  You can see more about it in this little video i made about it:

I have a VXR-7000 used off of eBay as a commerial repeater.  I have $400 into this setting up a repeater...  Antenna was hand me down, came with Duplexer, just add ground, mic and wired.

Good video and very simple. Any plans to test/try Linking the repeater?

My question is, how do you put a repeater up at a repeater site such as Sunset Peak or other sites?
