2025 King of the Hammers Off Road Race

[Mikek]

2025 King of the Hammers in Johnson Valley wrapped up this weekend. Here's what I gathered over the couple of weekends I was there.
*BLM Ranger units on 166.75 were encrypted for the most part, but dispatch was in the clear. And yes, they had both analog and P25 going on the same frequency with unique channel names and usage for each (166.4875)... Surprisingly, I didn't hear any issues with that.

CALCORD was also used for air to ground. Heard comms when someone was airlifted out for a broken leg.

Third line under use seems to read "BLM Admin KOH." What does KOH mean?

OES has specified statewide that CALCORD be the on scene helicopter coordination frequency. This for all agencies, federal, state and local. On large wildland fires the comm plan always includes this frequency. Some other states use 155.340 or what we, in California, call "HEARS" or Hospital Emergency Administrative Radio System," if I remember correctly.

CALCORD is the California specific frequency as the name implies. Other states have their own usages, usually from the federal interop selection of frequencies. Arizona uses VFIRE21 as primary EMS air to ground, whereas Nevada uses VMED28 as primary.

The map shows Arizona is using V Med 28 like most other western states. Interestingly, North Dakota is using V Law 31. Washington and Oregon are now using V Med 29. In 2019 these two states had yet to designate a frequency.

I had some trauma that is causing an accelerated decline. Life has been pretty good except for 6 days.
