Just after 9/11/01, some of the 11,000 FCC licensed volunteer Amateur Radio operators in Minnesota built a radio based data network covering our region.   We passed the hat and collected enough funds and donated equipment to complete a network using legacy AX.25 packet radio technology, which has been running to commercial reliability standards since 2002. 

We provide volunteer medical communications planning, equipment and support for Twin Cities in Motion. We are now deploying our third generation very high speed (megabits) data network, using high power D-Star DD mode radios married to OLSR mesh technology @5Ghz.  (Channel 157- 802.11a) We hold monthly work sessions (3rd Sat @Macalester Plymouth United Church Bsmt 11-3) to upgrade our technology and do event planning. 

Our organization leads the delivery of up to date, NIMS-friendly volunteer emergency communications in our region.   We work across all served agencies, and are happy to provide free advice in managing complex emergency /health communications challenges using the latest technical best practices and trained, dedicated volunteers.   

Our latest talk was presented at TAPR DCC 2013:  http://www.slideshare.net/ny9d/marathondstar
