Welcome to:

"RBTIP"
So, you want to build a repeater?

The Repeater Builder's Technical Information Page^® is an informational help site by Kevin Custer W3KKC.
This is the largest repeater information site in the world!

Below is a Google ad (to help pay the bandwidth and hosting bill).   No endorsement of the products is implied.

Donations are appreciated for the continued availability and upkeep of this site. We have over 9,200 publicly-accessible files occupying almost 9GB of server space. All of it is freely downloadable information, and our server transfers (i.e. downloads) over 250GB per month! The repeater-builder Yahoogroup that is associated with this web site has over 5,200 members worldwide and is a tremendous resource of technical knowledge on repeaters and repeater-building, be they amateur, commercial, GMRS, public safety, CAP, or ... The contents of the information pages at this web site are totally dependent on donations of information. If you have expertise on a particular piece of equipment, or detailed knowledge on a topic, please consider contributing an article or two to this web site. This web site is privately owned and operated; all financial support comes from donations from individuals. There is little advertising on this web site except for a few small amateur-owned companies that manufacture boards and parts of interest to the repeater community, and a few Google ads like the one above that help pay the hosting fees.

Please help support this site -- we accept donations using PayPal.
We also accept donations using a credit or debit card via PayPal.
Thanks!
