Established in 1971, the Cactus Intertie System is a private UHF amateur radio system consisting of a large number of remotely controlled base stations, or “Remote Base” for short, which are interconnected utilizing full duplex links. This linked system covers large portions of California, Arizona, New Mexico, Nevada, Utah, Colorado and Texas. The system also extends into Washington D.C., Maryland, Virginia, West Virginia, Pennsylvania, Delaware, Atlanta, Georgia and Kalispell, Montana.

Cactus Intertie, Inc. is a registered 501 (c)(3) non-profit organization.  Also known as “Cactus Radio” or the “Cactus Intertie”, along with its affiliate clubs and organizations build, own, operate and maintain the remote bases throughout most of the United States. Most of these systems are accessed using locally coordinated frequencies and are located on mountain peaks that provide wide area coverage.  The early development of and adherence to high technical commercial standards in the RF equipment, audio tailoring and the system controller requirements, makes the Cactus Intertie System one of the most reliable and best sounding fully duplexed linked radio systems in the nation.

The remote bases owned, operated, and maintained by Cactus Intertie, Inc. are primarily funded by donations and membership.  Mountain top radio site rent, as well as the radio equipment doesn’t come without on-going costs. Therefore, it is important for us to maintain a healthy and supportive membership.  Furthermore, it takes members to achieve our mission to provide communications support for public events and emergency/disaster service organizations.  We are proud of our ongoing support to the American Red Cross, as well as the California Governor’s Office of Emergency Services.

If our organization appeals to your values and you have a desire to be more involved in both the hobby and public service, please visit our “Membership” page for more information.  Or, if you simply wish to support the Cactus Intertie System, please consider donating to our non-profit organization using the “Donate” link above.  

Thank you.
