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 legacy AX.25 packet radio technology, which has
been running to commercial reliability standards since
In order to provide modern, standards based,
high capacity volunteer emergency communications services, we built
an advanced digital backbone supporting voice and data
D-Star(r) from Icom. We have five rooftop D-Star
data nodes (100 kbps) and several mixed data/voice
repeaters online at all times to support volunteers in
our area. At our events our operators are embedded
in our served agencies and can also use a mixture of
technologies as directed such as the State ARMER system,
802.11, mobile devices and rented trunking radios to
meet the needs of the events and to ensure our operators
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 (3 megabits) data network, using high power D-Star DD mode
radios married to OLSR mesh
technology @5Ghz. We hold monthly work sessions
(3rd Sat) to upgrade our te
chnology 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.
