  3. 3. Medical Personnel on the Course The marathon has one of the best medical teams in the industry and is led by Medical Director, Dr. Bill Roberts. On average, one to three percent of every 1,000 entrants will seek medical assistance along the course or at the finish line. With that in mind, 300 medical personnel are positioned along the course and at the finish line. All medical personnel can be identified by their orange vests and all are trained to assist in medical care. A medical team will be assigned to each aid station along the course. There are also medical volunteers stationed at many of the mile and half-mile marks of the race course. Communications personnel in yellow shirts are paired with the medical volunteers to provide access to mobile medical teams and ambulance services. Seriously injured or ill runners will be transported to the nearest hospital from any of the Medical Aid Stations on the course, and well runners who drop out of the race will be taken to the finish area. Medical volunteers will have first aid supplies at every medical location. What is our Job? eekend/marathon/medical_information/ Accessed 8/13/2013

  15. 15. The St Paul End of the Dish Link Note Minneapolis in the distance- 9 miles
  16. 16. HC Command Truck Mesh Upgrades • We have had excellent results for ten years borrowing a communications vehicle (ICC) and volunteer team from the Hennepin County Sherriff. The primary mission is missing runner tracking and family reunification. They run one of the four injured runner tracking radio nets. The vehicle is the interface between the medical volunteers (mostly Amateur Radio) and Marathon rented radio system and the Statewide ARMER radio network. • At the recent Red White and Boom Half Marathon (7/4/19) the volunteer team was directed by Hennepin Healthcare to coordinate EMS dispatch for the event. We also tested a new mesh live video system that can cover downtown Minneapolis or St Paul, using new rooftop antennas. • We just added mesh antennas and radios to a second Hennepin Country vehicle (ICP), for similar role
  17. 17. Project List 02/20 • Add more mesh stations – Metro counties (Bloomington), Hennepin Healthcare, Dakota County • Packet link upgrade- Rush City (Duluth) + Rochester • FM/(Fusion -DARC) Repeaters St Paul, Minneapolis • One more D-Star repeater • More county command trucks on Mesh • New home for MAPLE packet node • New generator/tower trailer commissioning • DMR repeater coverage - Duluth • New served agencies/events (Klondike /Loppet) • Hospital Compact support
