Heard this morning (Saturday) as I drove thru the area from Prescott to Wickenburg:
163.100 (000.0) "Heli Base". BLM crews coordinating helicopter dips in the pond at the Hidden Springs ranch in Peeples Valley. "Luke Lake" is a small crescent shaped pond right off of Hwy 89 the choppers were dipping in one right after another.
411.995 (R) "Air Tac". Sounded like chopper to chopper traffic.
159.955 Unknown fire crew working the line
155.400 (R, 141.3) Yavapai County crews working on the "Union" Channel
155.160 Same Yavapai County crews using "County SAR", telling contact to go to the "Union" channel.
411.995 is probably a link frequency for a VHF-AM air to air tactics frequency. The logistics function is the only function to utilize UHF frequencies for simplex and repeater communications on handhelds provided from NIFC caches. Sometimes a UHF frequency is used simplex in camp and called "Camp Net." The NIFC system has quite a few of these UHF frequencies that can be used to link VHF-FM command repeaters together. They are also used to link AM aviation frequencies from portable VHF AM remote bases temporarily placed on high peaks in the fire area.
I have all this documented in a Wiki article that is reached by accessing the "Nationwide Frequency" portion of the database. Scroll down to the link for the "National Incident Radio Support Cache" and once there, hit the Wiki tab. I really like getting reception reports to confirm the information I'm able to get from time to time.
If I remember correctly, the Yavapai SO has a repeater on Mt. Union.
163.1000 is used as a "deck frequency" at heliports and air tanker bases. It sounds like they are using it on this fire at a main watering source.
I don't have 159.9550 in any of the information of the state's from 2015. I'm not sure of when I will get to see their 2016 info, but will keep that frequency in mind when I do. I could not find any licences issued to the State of Arizona for that frequency either.
Welcome to the world of wildland fire listening. This ain't the midwest anymore!! I say that because the western U.S. has a lot of fire dependent ecosystems that burn far more frequently than those in the midwest. Actually I call anything east of the east boundary fence of Denver International, the eastern U.S.! :wink: From your home you should be able to get some Prescott and some Tonto National Forests listening in. I'm not sure of how they link their repeater sites, whether by microwave or in the 406-420 range. I think Mt. Ord is the hub site for the Tonto and Union or Mingus on the Prescott. You will also be able to pick up the Phoenix District of the BLM fairly well. radioprescott has a lot of knowledge of the federal land management agencies in Arizona and has made significant finds and database submissions over the years.
