Frequently Asked Questions

What is the Armadillo Intertie System?


The Armadillo Intertie System is a system of UHF repeaters that are interconnected with full-duplex links. The system was built by a group of friends who wanted a radio system which was reliable, and which had coverage in many areas of Texas. The system is connected to the Cactus Intertie System, which covers large portions of California, Arizona, New Mexico, Nevada, and Utah.

Who operates the System?

Armadillo Intertie is a privately owned and operated system. It is managed by Armadillo Intertie, Inc, a Texas non-profit corporation. The Armadillo Intertie System is a members only system. Due to it's complexity everyone is considered a control operator.

What kind of person uses Armadillo?

Amateur Radio may be for everyone but Armadillo isn't. We are selective about our members because we want a system that is enjoyable to operate, not one where there is always controversy. Our members are generally good friends and have been for many years. We socialize with each other at all levels, not just on Ham Radio. We generally seek individuals who:

  • Will participate in the system more than just by talking on it.
  • Are capable of making technical, financial, or other contributions for the benefit of the organization.
  • Are generally technologically-oriented or work in a technologically-oriented field.
  • Are enthusiastic about Armadillo objectives.
  • Take a professional approach to an amateur avocation.
  • Are socially compatible with other members of the organization.

What does the group expect from its members?


Members are encouraged to participate in group activities. One of the main reasons the system was built was so the members could organize social gatherings.

Financial support

Members are expected to support the group financially. This stuff is expensive - if you use it, you should help pay for it. By the same token, this is one of the main reasons the system is closed - it's not fair to the people who paid for it to have people who didn't using the system.


Members are encouraged to make a contribution to the system other than just talking on it. There's always something you can do to make the system better for everyone.


Members are expected to comply with a few simple rules about how the system is used and controlled. This includes informing non-members/visitors that the system is for members and invited guests use only. Non-Members interested in membership should refer to the Board of Directors page and contact the director nearest you.


We want the members to be enthusiastic about the system and its goals.


Members should be reliable. If you say you'll do something, do it.

How does one become a member?

Membership to the Armadillo Intertie System is by invitation only. You must be recommended, in writing, by a current member who is willing to vouch for your credentials.

Interested persons are encouraged to listen to the system to decide if the activity on the system fits their interests.

Interested persons should get to know other members by attending group activities. Demonstrate your desire to participate.

Express your interest by contacting someone in the group or one of the directors.

Expect a reasonable time for determination of member status. We need time to get to know a candidate.

What are the objectives for the future?

  • Reliable linking of major areas of residence and travel of the members.
  • Handheld coverage of all metropolitan areas.
  • Quality, quiet, duplex operation in areas covered.
  • Positive remote control of each site.
  • Consistent and known system architecture.
  • Continued cooperation with the Cactus Intertie System.
