Ham radio operators provide essential communications support for various events through the use of mobile communications trailers with generators and antennas. This includes providing backup communications, monitoring medical situations, tracking locations, and reuniting families. The organization aims to have more robust and redundant mobile communications assets statewide to support agencies and response efforts. Strategies include networking trailers, using mesh networking and video capabilities, and training volunteers to work with agencies.

2. Amateur Radio Public Service in 2022
• Is standing around for government/cellular radio systems to fail
boring?
• Embedded in agencies- EMS, hospitals, counties, NGOs
• Pivot from written message traffic to databases and dashboards
• Capabilities + direct service
– Missing persons/ family reunification
– Aid stations /medical support/ medical command centers (medical
resource shortages)
– Weather spotting
– IP Video
– Duties as assigned (food distribution, IT support etc.)
– Disaster clean up (Crisis Cleanup, VOAD, etc.)
• Assets*- repeaters, networks, generators and tower trailers
• A Ham Radio license is a valid credential
• “Unwanted Volunteers” are prized, trusted and recruited
*(Go-kits are not welcome at large
sporting events )

6. Other Amateur Duties/Roles 2022
• Medical Command Center, staffed 100% by radio amateurs. All non-911 volunteer resources are in our scope. We also
monitor 911 radio traffic using authorized volunteers to ensure our reports are accurate; e.g., the right bib number and
runner cross street location.
• Provision of a fully redundant "lights out" backup radio system. This is a specific, requested function.
• Assignments on Command trucks, which house some of our net controls who provide liaison to government radio systems
and are under our direction.
• At our events and others, 350 rented trunked radios are the backbone of event communications (a best practice). We
provide net controls for the medical channels - the Incident Commander checks in and is on our rented radio nets all race.
• Transport tracking and hospital capacity management -- using secure systems and authorized officials we ensure families
know where runners are transported. We do not share medical condition information.
• Family reunification -- if runners drop off the course or are injured, we reunite runners with their families.
• Wheel chair and medical electric cart dispatching.
• Aid station support on the course.
• Hams every mile for dropped out runner reporting and situational awareness.
• Shadows for key officials as requested.
• Medical tent runner check-in and check out.
• Support and provide student EMTs, Medical Reserve Corps and volunteer resources, such as mutual aid at the sprawling
finish line area.
• Support published disaster and evacuation plans.
• Support bike medics
• Track SAG (Supplies and Gear) bus location and passengers.
• Train users on medical applications.
• Provide input to the development of ICS 205/206 frequency lists and Incident Action Plan (IAP).

software supports real time
data and or dashboarding?

8. Ham and Provider Strike Teams
• At our events, we are operational assets not support (i.e.
not in Service Branch)
• The Service Branch under logistics is not “customer
facing” – the Medical Unit is internal

9. As a Strike Team what skills are needed?
• Yes
– First aid (as directed) i.e. EMT courses
– Traige (as directed)
– Ground truth (25 homes destroyed vs a ruined shed
from a fallen tree)
– WebEoc etc.
– Video
– In EMS lingo, volunteers only handle “Green” cases*
• No
– Land mobile programming
– Winlink
*One of our EMS partners brought this up with Astroworld- 2021

10. Why Mesh?
• Served agency leadership is increasingly using real time
dashboards, databases and video - “Better data better
decisions” is a common request/theme
• The Red Cross has moved to a cloud database called RC
Care
• Mesh, based on standard, low cost, outdoor rated WiFi
hardware, offers high data rates and allows peer-peer
connectivity
• Very short tactical range except dish to dish (line of sight)
• MN ARES has adopted AREDN software and Channels -2
and 180, 10m bandwidth:

30. Proposed Silly* Trailer Rules
• Trailers get cute tactical names/colors (ask your wife)- consult your kids on the paint job
• Trailers are tested with our Strategic Technology Reserve assets and local mesh standards. We hand
out radios and antennas for this. If everyone sets them up their own way they cannot work together or
add value.
• The ownership should be widely distributed to prevent any one person from taking them over.
• Ideally we have a three hour response time state wide. Seven here are on 20 minute warm standby.
Four hours to find which box in the basement has the antennas and which bin has the feedlines is not
good.
• Trailers should travel in convoy for the best visual effect. I can see these in parades, county fairs, etc.
• Citizen Science is the idea here- creative technology is encouraged- this is a
technology/service/hobby project. Remember "State of the Radio Art" from someplace?
• If more than one trailer is needed at once - ask- "Barn Raising" is the model
• These are intended to be cheap, abundant and deployable- more like cattle vs a prized race horse. If
you have $10,000 in it or it is powering your house it can't be out helping others.
• The idea is we are volunteer Ham Radio operators - think bass boat armada for water rescues.
• Hams in a given county should have at least as much rolling tower/generator capacity as the County

*Every effort is being made to not take this effort too seriously. A beverage cooler was a suggested add-on.

32. Some Strategy Advice
Volunteer Emergency Services Maturity Model (K8JK)
1. Integrated volunteer emergency management
(MNVOAD-ground truth and CAN-P reporting)
2. Family reunification /Medical management
3. Interoperable communications /backup EOC staffing
4. Amateur Radio traffic handling /shadows
5. Backup communications
Vision for ARES® 3.0
Mission: To provide state of the art volunteer emergency communications and IT Service Management to government agencies, events,
NGOs and the general public.
Divisions:
1. Government. Trained, vetted individuals to meet demanding government volunteer requirements
2. Events. The largest outdoor events depend on dedicated, trusted volunteers to enhance participant and spectator safety
3. VOAD and NGO support. Volunteers helping volunteers partnering to deliver critical support to those in need
4. Innovation Lab. Uniting builders and makers to develop technical solutions to meet current and emerging challenges
