Welcome to BATS and CATS and RATS. Here are some amateur radio-related links that might interest you. The xATS systems focus on high-density digital data, video and telephone communications via amateur radio using all of those federally-allocated standard-carrier frequencies from DC to light!

There are many connectors to the xATS services. Since we are Amateur Radio oriented, the users are mostly other amateur radio groups and clubs, and assorted disaster services. Some of these impressive xATS users, and other impressive users, are listed below. Also included are some Amateur Radio related information services and some specialized non-Amateur Radio services which may interest you.
