Currently, the system employs fifteen repeaters. That number may increase or decrease, depending on equipment status and various other factors. These repeaters are linked together via VHF and UHF radio. There are no complex control codes needed to operate distant repeaters - simply transmit on your local repeater frequency and you're connected with the entire system. Links are enabled on a fulltime basis.
The 145.310 MHz repeater on Mt. Thorodin serves as the control for the system. When you hear the proceed tones or the repeater ID, they come from the Mt. Thorodin repeater site which is IP linked to Salida, Cheyenne Mountain, and the Thorodin Mountain Receiver Voter system. The Colorado Connection uses some GE Mastr II on the western slope and GE Mastr III on the Eastern Slope. The GE Mastr II repeaters are being replaced with GE Mastr III repeaters and Kenwood TKR-780 or similar repeaters. The connection also uses GE Custom MVP transceivers as link radios and these are being phased out and replaced with Kenwood UHF and VHF transcievers as well as significant amounts of ham-band microwave IP links along the Eastern Front Range. For lightning protection, we use Polyphaser products. Link Communications RLC-1, RLC-4, and RLC-5 and S-COM Controllers are used at a variety of sites, although several sites use an electro-mechanical link box with no solid state controller. As we improve our repeater sites with new equipment, we've used WACOM duplexers. Improvements are still needed at many of the sites to upgrade to Wacom products. We use many different antenna products. Cushcraft, Comet, Diamond, and commercial antennas are used at various repeater sites. (Of note, we don't endorse these companies and/or their products. We've included this information only to satisfy your curiosity.)
Below are links that describe the Colorado Connection repeaters, with pictures from several of the sites. A detailed status report is available by clicking on the green, orange, blue, or red balls under the status column. Approximate coverage area of each repeater is available by selecting the appropriate map in the coverage column. The coverage areas are somewhat conservative. They were generated with computer software and USGS contour data that in some cases is outdated. They are not meant to be completely accurate, but it's quite interesting to see how mountain peaks create strange and unusual RF patterns. Also, you may note that each map does not share the same scale.

Several independent repeater systems have remote base capability to access the Colorado Connection. These include, but are not limited to, the Grand Mesa Repeater Users Group with the 145.220 MHz repeater (with a pl of 107.2 Hz) on Douglas Pass in western Colorado, the Sinbad Desert Amateur Radio Club with the 147.320 MHz and 449.050 MHz repeaters (both with a pl of 88.5 Hz) on Bruin Peak in eastern Utah, the Roaring Fork Amateur Repeater Co-Operative with the 147.300 MHz repeater (with a PL tone of 107.2 Hz) near Aspen, Colorado.
