 Ka'u Coffee Trail Run Information:

I'm looking for volunteers that have DMR and analog equipment. DMR (digital mobile radio) will be the primary mode of communication for this event. If you don't have a DMR number please go to RadioID - Register and get a DMR ID number. If you don't have a DMR radio I can provide you with a radio; but you'll need to register and get an ID number if you don't have one. If you would like to volunteer please send me an email: 
The Ka'u Coffee Trail Run will be on September 21, 2024. All Ham Radio Volunteers will meet at the Coffee Mill at 5:30am for a briefing before the race. The 50k starts at 6:00am, Half marathon starts at 7:00am, 10k at 7:15am, 5K at 7:30am. The event ends at 3:00pm or if all runners have completed their distance. I have a Motorola XPR 8400 UHF DMR repeater on 444.950 CC1 at the Ka'u Coffee Mill.
