Found a few more interesting items from the 2020 Las Vegas document
'NV EMS 1' - 154.28 - (maybe is typo - maybe is EMA 1?)
'VHF Tac 1' - 154.10 - CG 71.9 - RX + TX - maybe a Clark County FD channel ?
"VMED 28 / Nev Coord 1' - 155.34
'VMED 29 / Nev Coord 2' - 155.3475
--------------------------
in the "Vegas Fire" zone / bank
"TOI 2456" - 172.275 R - 164.50 input - (the input PL is different from the other repeaters on this channel pair - perhaps this is a USFS transportable repeater)
"Tac 4" - 166.1825
"Tac 5" - 166.8875
(there is no indication as to who "owns" those Tac channels)
Of course we all know that 154.280 is V-Fire 21, formerly known as "White 1" among a bunch of other names. It is the nearly universal fire mutual aid frequency. I don't have anymore light to shed on that one. zerg, will have to spent some time, brief as I have, to guide my way to some additional knowledge on this
The 154.340, "VMed28" and 155.3475, "VMed29" are also called "NEVCORD 1" and "NEVCORD 2" in Nevada. These are listed because 8 western states, as well as South Dakota and Nebraska have agreed to use at least 155.340 the primary air to ground for med evacs on wildland fires. For whatever reason, 155.4750, "VLAW31" is the chosen freq in North Dakota. In California, the frequency 156.0750 has been agreed to. It is licensed by the CA Office of Emergency Services as "CALCORD." It is a frequency used all over the state for multiple agency incident coordination. In my hospital days and late Hubby's volunteer FD days we saw it used when a large number of agencies responded to the start of incidents. We had some major rock/mud slides on a major mountain road with USFS, State Parks, Cal Fire, Caltrans (CA DOT), the county (S.O., FD's, Public Works, Public Health) and EMS responding. CALCORD was shouted from the rafters so that is what we used first on scene. VMED28 used to be called "HEAR" in California which stood for "Hospital Emergency Administrative Radio." I know every hospital in Southern California monitored it and had drills from time to time. It was like VFIRE21, except for medicine.
For some reason Washington and Oregon have not set a standard frequency. Nevada and Utah are the only states to designate VMED29 as a secondary, just in case two "incidents within an incident" (in this case a medical among PS Safety people) occur within listening distance of each other.
Hopefully this map won't give me trouble as an attachment. It is the EMS wildland fire medical evac air to ground map for the west.
Oh, for heaven's sake! I have the hardest time posting maps. It says "the uploaded file is too large for the server to process." I don't want to post it in B&W so I give up.
As for Tacs 4-5, this is the first place I've seen this. I'm going to have to dig around more in "Hubby's Notebooks." I'm working on, at a snails pace, a listing of tactical frequencies adopted by each GACC (Geographical Area Coordination Center - 10 in U.S.). NIFC told the agencies to not use the NIFC tacs for initial attack or locally managed incidents, that they are only for national Type I and Type II incidents. Since then area, sometimes on a state by state basis, tacs have been assigned. When these frequencies are assigned the USFS and BLM pool what they have and in Utah, the state contributed one of two as well. The GACC controls their assignments so they really aren't "anyone's" frequencies. I'm glad to find out about these two, I will add them to my list. Someday I might complete it.
