The Colorado Emergency Reporting Net monitors the Colorado Connection Statewide Repeater System. The Colorado Connection is a system of linked 2-meter repeaters that are built and maintained by volunteers. The system is open to all licensed amateur radio operators. The Colorado Connection is not a club with dues and membership, it is a system supported solely by voluntary donations and managed by a board of volunteer directors.
The system covers about 60% of the area of Colorado and a large part of the I-25 and I-70 Interstate highways. The Colorado Connection is a treasured and important statewide system used for emergency communications. The system is also used for talking to new people, for nets, for ARES, the Colorado traffic net and other groups for on-air meetings. The system has coverage where cell phones do not work in rural and wilderness areas. For information on coverage, please see our website at www.colcon.org.
The system is connected full time so that when you use any repeater you are transmitting on all of the repeaters. This does require that you key your radio a second or two before speaking to allow all links to be active and after the courtesy tone, you may proceed with your conversation. This will allow people to hear all of your transmission and allow for stations to break in for emergency traffic.
Without your support, the Connection cannot survive. We have ongoing expenses that include equipment, rent, power bills and insurance. If you use the system and find it useful, consider supporting the system with a donation of time, money, or both. We appreciate and need your support! Donations above those needed for maintenance are used for system expansion and reliability upgrades, so happen “at the speed of donations”. Monetary donations can be via PayPal on our website, Amazon Smile or checks by mail. To donate time and effort, sign up for our mailing list.
