Just after 9/11/01, some of the 11,000 FCC licensed volunteer Amateur Radio operators in Minnesota decided they could build a radio based data network covering our region.  This network would provide a reliable backup email and data capability to support them in the event of an emergency that disabled or overloaded normal communications channels.  We passed the hat and collected enough funds and donated equipment to complete a network using AX.25 packet radio technology, which has been running to commercial reliability standards since 2002. 

In order to provide modern, standards based, high capacity volunteer emergency communications services, we have built with our own funds and are now making available for general Amateur use our D-Star(r) 90+ kilobit TCP/IP data network and related VoIP capabilities.   This technology, which supports web based emergency computer applications, moves Amateur Radio back to where the FCC Part 97 rules say we belong- advancing the state of the radio art. 

We provide volunteer medical communications planning, equipment and support for two large urban marathons and a half marathon. We are now deploying our third generation very high speed data network, using mesh technology.  We are also building a linked, D-Star DV capability statewide to overlay the current packet network.

Our organization leads the delivery of up to date, NIMS-friendly volunteer emergency communications in Minnesota.  We work across all served agencies.
