BLM Bishop Field Office

[SCPD]

The BLM radio system in the eastern Sierra is used very infrequently, so it's been tough to find their frequencies for several years now. The BLM and the U.S. Forest Service integrated their fire management organizations on the Inyo NF and Bishop Field Office many years ago and the BLM has been using the Inyo NF Forest Net ever since (now configured with a north and south net).

I was able to confirm today that the net is on 166.875 with a repeater input of 169.7125. Tones are (north to south) 7 - Sweetwater (near the CA108/US 395 junction), 4 - Potato (east of Bridgeport), 8 - Silver (northeast of Bishop) and 6 - Cerro Gordo (east of Lone Pine).

l have not found the down link from Silver Peak, which is the hub of the system. The down link used to be on 417.025. I've not heard and BLM traffic on it, but it is still in place with an analog receiver. It also receives the backcountry net of Sequoia-Kings Canyon NP, which uses digital so the resulting noise makes it more than annoying to listen to.

Interesting that the database is "close" - 166.900? thanks for the update!

BLM Fire Net? 169.7125mhz pl110.9 Rptr Northern Mono Co(New?)

Today 08-05-2011 @ 14:30 hrs from Gardnerville,Nv i heard "Engine #3131" calling unknown Dispatch on {I Quote}"BLM Fire Repeat" using 169.7125/110.9 Repeater with a somewhat ok signal (10-01 & 1/2).

Advising {I Quote}"Clear Pickle Meadows enroute back to Topaz Station"
I know where these locations are and i always heard Topaz Station units calling Minden Dispatch USFS HTF-Net, this is new.

It sounded like they were calling Inyo? but not sure due to signal, unless this is a link using 169.7125/110.9 and repeating all traffic like a repeater i dont know im going to listen to 166.8750 also to try and get clarification.

But still i dont understand why they were not calling Minden on HTF-Net.

BLM Carson City District has a Rptr on Corey Pk (Mineral Co) but nothing in the Bridgeport area of Mono Co.

Only HTF-Net on Sweetwater Summit or Mean Peak.

Has anybody else noticed this?

Or have an answer to my question?

Again:
169.7125/110.9 was used being call "BLM Fire Repeat"(Both sides heard)
169.8750/CSQ HTF-Net has been used for the Topaz BLM Station (U.S.395@S.R.89).
169.9875/146.2 BLM-Net Carson Dist rptrs dont cover that area,and have never been called BLM Fire, its always been "Minden Disp" on whatever mtn top site Example: "Minden Dispatch" "E-3131 on BLM McClellan"

Ok just now i heard Engine #3131 Calling "Inyo" @ 15:00 hrs advising "In station Topaz" So that clarifies most of what i needed to know except 166.8750? Is this a input or output freq and are they using a tone?
169.7125/110.9 sounds to me like a rptr,not an input unless the input acts like a link?
Im going back to monitoring both freqs right now to see if i can answer my own question.

FWIW, that update (post #1) never made it to the database....

If you haven't already, can you submit those to the DB so it can be updated.

Thanks.

Don't be too quick to add this info to the database. This needs to be figured out first.

Bill, thanks for the report. After writing my post last year the BLM net under discussion here changed frequencies and I've been unable to figure out the new frequency. I'm going to put the frequency you mentioned into my scanners and see if I receive something.

Your confusion about who is dispatching whom is understandable so I hope this will help. The Topaz BLM units are part of the Bishop Field Office of the BLM, not the Carson City District and not the Humboldt-Toiyabe NF. The Bishop FO is dispatched by "Inyo," the joint USFS/BLM comm center in Bishop. They normally contact Inyo on the Inyo Net, which is shared by the Bishop FO and the Inyo NF, on the Sweetwater repeater, located near the CA 108/U.S. 395 junction. This repeater is accessed using Tone 10, or 107.2. I can't hear Minden dispatch from here so I don't know how they are dispatched up there when the respond to HTF or the BLM Carson City District fires. The BLM land near Markleeville is in the BLM Carson District and the Antelope Valley is in the BLM Bishop Field Office of the Central California District.

BLM/USFS on the Inyo NF/Bishop FO call the BLM Net, "BLM net," or sometimes "BLM." It is often used as a command on incidents on the northern portion of the Inyo NF or the Bodie Hills area of the Bishop FO when the Inyo NF net is busy. The closest repeater to Topaz that I know of is on Potato Peak, just east of Bridgeport. It is accessed on Tone 4, or 136.5. If a repeater has been added up in the northern portion of Mono County using Tone 1, 110.9, sounds logical to me. It is possible it is on Sweetwater as well. If you heard both sides of the conversation you have heard the repeater output, which means I will most likely hear it down here on the Potato Peak and Silver Peak repeaters (NE of Bishop). I may also be able to hear the Sweetwater repeater as well.

The USFS and the rest of the federal government do not use VHF high for links, but the UHF federal band (406-420). I will monitor 169.7125 and go from here. Bill, you may have provided a break through on finding the Bishop Field Office net. It may take some time to confirm as the use of this net is infrequent and used only when there are multiple fire starts on the northern portion of the Inyo NF.

Well today i started scanning/searching all BLM/USFS Freqs i have loaded.

At 16:20 hrs i heard an unidentified unit.

[Quoting] Minden (????Unit) HTF-Net Tone 6 (Mean Peak) clear Bridgeport enroute Topaz.

10-04 En-route Topaz,Minden clear at 16:20 KOC400 [Unquote]

If iam correct BLM & USFS share the Topaz Station, ive driven by it many times noticing
a (Lime/Yellow type III Brush rig) BLM #3131 and (Green USFS Type III Patrol? Rig) HTF#71?? parked there.

But my input to this mystery is that Inyo on BLM Tone-1 (110.9) Repeater is the same signal strength as Mean Peak HTF Tone-6 (156.7).

HTF currently does not have a Sweetwater Site yet (I read a bulletin on the USFS Toiyabe webpage about the Construction of a joint USFS/USMC MWTC Sweetwater site but for exact details i would have to locate website again to read.
(Correction i just read your Smokey Site again and see that Sweetwater is up and active,disregard above Sweetwater info, a new mystery begins for me to find out who is on Sweetwater, unfortunely FCC Data base dosent list USGOVT users (I know you know that just letting you know i knowLOL)


Sweetwater site for Mono County Sheriff/Fire, Cailf Dept of Fish & Game,MWTC comes in extremly well at my location as well as Corey Peak.

KOJ437-BLM Carson District uses 169.9875/146.2 out, In 162.2375/151.4 on Corey peak.
(They dont have a standard numbered tone list/Odd input tones like 173.8 & 186.2 for example)

KOC400-HTF Bridgeport/Carson? District uses 169.8750/167.9 out, In 170.4750/167.9 Tone-7
(Again odd that the entire HTF 169.8750 is CSQ except Corey using Tone-7 (167.9) Xmt & Rcx.)

Im kinda thinking it is Mean peak but guessing aside i will wait for #3131 to Advise BLM Inyo what site their on, unless they do it different down there?

Now thinking that it maybe could be Conway Summit? Signal is about the same.
Im going to look at my Mono County Tone list of repeaters i have listed in my personal log with simular signal strengths and i will post those mtn tops i can hear at my location.

FYI im using a Tram Model 1487 VHF 3x5/8 wave Base Antenna/LMR-400 Coax/Height 20' above my 5,000' elev for RCX using the Uniden BCT-15, i get amazing distance from this combo, yesterday evening i was RCXing Napa,Yolo,Glenn,Butte,Santa Clara,Contra Costa,San Benito,Sonoma Co Law/Fire and Solano is almost full quieting!

Cal-Fire Red Bluff ECC on Tuscan Butte,Cal-Fire St Helena ECC on Site near Berryessa?

2-Meter Sites confirmed-Mt tam,Mt diablo,Sutter Buttes,(Mt Vaca Almost Full quieting)

Just a short list of captures that vary (Inversion Layers?)

But iam on top of the USFS/BLM thing, also ENF Forest/Admin Nets,PNF Forest Net,TNF Forest/Fire Nets,BMU Tahoe Basin Net,Central Nevada Interagency Disptch Center (Star Pk) are being monitored with varying degrees of signal strength.

168.5500 (Smoke Jumpers),168.6250 (Gaurd),168.6500(Flt Flw),166.6875(Air to Ground Pri) 166.8750 (Air to Ground Sec) currently very active, first time i heard Smoke Jumpers here on that freq a week ago.

Yes i noticed very limited use on 169.7125/110.9 do you have an idea of the input freq?
Also do to the volume being low i believe this is no doubt narrowbanded and maybe p25 for use at later time.

Topaz station is interagency effort with the BLM Bishop Field Office and the Bridgeport Ranger District of the Humboldt-Toiyabe National Forest. From time to time there might be engines from the Carson City District of the BLM. I don't remember the Field Office in that district that is involved. The Carson City District is divided into two Field Offices, one for the west and one for the east. There also may be engines from the Carson Ranger District of the HTF stationed there temporarily. There unit designators are 71xx.

Type III engines are not used for patrols which are usually Type VII or Type VI engines. They don't qualify as an actual engine until two firefighters are assigned to the patrol. When they are staffed with one person only that person is a Fire Prevention Technician.

Your observations on signal strength similarity for both Mean Peak on the HTF net and the unknown location of the BLM Bishop Field Office repeater leads me to believe the BLM repeater is on Sweetwater depending on your location in or near Minden/Gardnerville. This is also supported by the fact that the Inyo NF has a repeater on Sweetwater (Tone 10). If the Inyo has a repeater there for the Inyo Forest Net it would be easier to put there than at another location.

Plug these two frequencies into your scanner: 170.550 and 169.900. These used to be in some handhelds I used on the Toiyabe NF when I worked there 1981-1988. Since then I've seen these frequencies on different lists, most of which I don't give any credibility to, but they are worth a try. These are both simplex tacticals.

The entire Toiyabe is not CSQ on the input, however, having the output frequency not carrying the input tone puzzles me. I can hear Cory quite clearly from here and as you say Tone 7, 167.9 is carried though to this repeaters transmit frequency. I've also heard Masonic (Tone 2, 123.0) recently and the input tone is carried over to the output as well. I don't get up to Minden, Carson City or Reno anymore so I don't get a chance to listen to the various radio systems up there.

You are located in quite a reception area. You are also hearing some tropospheric ducting on some of the frequencies you reported, that is if they are only heard occassionally. This is my opinion anyhow. I used to have a narrow path of distant reception that allowed me to hear the Mt. Hoffman and Wawona repeaters of Yosemite National Park and the San Benito/Monterrey Unit of CDF among others. I could pick up a Monterrey FM radio station that played the best music. One night I was able to pick up a Monterrey TV station in the early morning hours when TV station KOLO Channel 8 used to stop broadcasting for several hours.

It's good to have you back Fred. These conversations are fantastic, and the rest of us just sit back and learn.

 

[SCPD]

Thanks. I'm in and out as I have my mother's estate to take care of and a good friend of my wife and I who has no family. He is in about year two of Alzheimer's disease and I have his power-of-attorney as well. On top of that I'm now driving for a taxi company in town, sometimes working 2 p.m. to 2 a.m. I'm running out of candles to burn on both ends. The result is I have to disappear from here for 2-4 weeks at a time.

The challenge for this BLM net is to now find the input frequency and the downlink frequency of the remote base on Silver Peak.

 

[SCPD]

The other possibility here is that the repeater on Sweetwater is now on 169.7125 and 168.125 is no longer in it. The main reason for having a repeater in the northern portion of Mono County was to provide communications for the BLM in the Antelope and Slinkard Valleys, with the engine stationed at Topaz.

To the west, the BLM land near Markleeville is administered by the Carson City District of the BLM whose next level up, the BLM Nevada State Office in Reno. The Toiyabe National Forest is in the Intermountain Region (R4) of the Forest Service, headquartered in Ogden, Utah. The Inyo National Forest is in the Pacific Southwest Region (R5) headquartered in Vallejo, California. Adding to the confusion is the BLM Bishop Field Office and the Inyo National Forest combined their fire organizations about ten years ago, and "Chief 1" is a Forest Service employee and "Chief 2" is a BLM employee and both supervise the combined organization. Chief 1 is the designator for the Fire Management Officer that works directly for a Forest Supervisor, but in this case supervises the BLM personnel as well. The Inyo's Forest Supervisor's Office and the BLM's Bishop Field Office are both in the same building and share positions as well, mostly in administration. The Inyo dispatcher is in the same building as well.

So a lot of confusion in the northern portion of Mono County as to federal land jurisdiction north of Conway Summit on U.S. 395. Sometimes when there are fires on the north side of State 167 north of Mono Lake the Inyo and BLM send units out of the new BLM fire station located just of 395 on the Lundy Lake road. The FS engine responds out of the Lee Vining Ranger Station. When I was working on the Inyo I was on a Type III incident management team that responded to a fire on Toiyabe NF lands so far north that we were nearly to Aurora, Nevada town site. This was due to the unavailability of anyone from the Toiyabe NF due to fires, you guessed it, on BLM lands in the Antelope Valley, the jurisdiction of the Bishop Field Office. No one could come up with a legal description (township, range and section) because it was so far off the Inyo map and none of us, at the time, had a Toiyabe NF map with us. This was in pre-GPS days so the location of the fire actually had to be determined later. After that I started carrying a mini-plans kit (I was a Type III plans chief, resource unit leader and situation unit leader) in my truck and a map of every NF in California, plus the entire Toiyabe, were in the kit. I also carried a mini T-card rack for keeping track of resources.

The Bodie Hills are also another area of "who does what?" Often the fire resources of the Bridgeport Ranger District are closer than the Bishop Field Office fires resources are. Minden may dispatch a response and not tell Inyo very quickly and so the Inyo sends a response also. If a fire is reported near Bodie State Park then CDF may sent a response via the San Bernardino CDF comm center. This could be solved by having Minden and Inyo communicate in a more timely fashion and by preexisting automatic dispatching. This is complicated by the two NF's being in separate Forest Service regions, with a huge difference in perspective and cultures between the two. The Intermountain Region was always trying to force us into having our management match the Forests of Utah and southern Idaho and they had no idea of what it takes to manage lands in the Sierra Nevada in California. The Regional boundary in Mono County crosses 395 at Conway Summit and I used to joke that there was a big black curtain running along the ridge that didn't allow anything to pass between. I think things have improved a great deal since I retired.

Anyhow, when I worked as the Recreation and Lands Officer (assistant District Ranger) on the Bridgeport Ranger District of the Toiyabe I wrote a proposal to have the BLM lands in California, both in the Antelope and Slinkard Valleys and the Markleeville area added to the Toiyabe National Forest. We did this at a time where we wanted to become more efficient by trading some lands between the agencies, this on a nationwide scale. The combined package got to the Congress and administration (Reagan's) and died. The Reagan administration wanted barriers and inefficiencies removed from and between government agencies. The whole package was shot down by western members of the Congress and I really don't know why. This strange fuzzy intersection of all these jurisdictions in northern Mono County and eastern Alpine County would have been eliminated in these areas if the proposal I had written would have been acted on. In Nevada the final result of this nationwide initiative is that 500,000 acres were added to the Toiyabe National Forest, but none of these relatively small jurisdiction situations were acted on.

I also proposed a couple of different concepts to the Regional Office in Ogden that raised a lot of eye brows and whispers of "R4 traitor" when I presented that the Toiyabe NF could be disbanded, with pieces going to the Inyo, Eldorado, Lake Tahoe Basin Management unit, and the Tahoe. I even had lines drawn on a map. The central Nevada portion of the Toiyabe NF would have been transferred to the Humboldt and the Mt. Charleston Ranger District to the San Bernardino NF. My alternate proposal was to disband Region 4 in its entirety with Utah going to the Rocky Mtn. Region (R2), southern Idaho and R4's portion to the Northern Rockies Region (R1) and Nevada to R5. The alternate of the last transfer could have been that central Nevada go to Region 2 as well and put western Nevada into R5. I kept telling everyone how much money and confusion we could solve with that one. No one paid attention to me of course, I was just a lowly Rec and Lands Officer. I kept bringing it up at budget meetings to satisfy the rebel portion of my career personality.

Bishop Field Office Net and other BLM/NPS Changes

Input for the Inyo NF south net is 173.8375. Input for the BLM Bishop Field Office net is 163.125, this confirmed. I also talked with a former co-worker and he indicated that the BLM net repeater is on Sweetwater and is accessed by Tone 10, 107.2. There isn't another repeater on the BLM net in northern Mono County except for the one on Potato Peak east of Bridgeport. This is the best information I have at this point for the BLM Bishop net:

169.7125 out / 163.125 in

Tones: (north to south)

10 Sweetwater Electronic Site (east of 395/108 junction - north 38 23' 18" by 119 21' 59")
4 Potato Peak (eat of Bridgeport, CA)
8 Silver Peak (east northeast of Bishop)
6 Cerro Gordo Peak (east southeast of Lone Pine)

Bill, have you heard anything on Tone 10, 107.2? I wonder if my information is dated and that there is another repeater, perhaps Leviathan. I think Leviathan would provide better coverage for the Slinkard Valley, however Sweetwater may cover well also.

Just today, I heard traffic on the Inyo NF net on the Sweetwater Repeater (Tone 10, 107.2) that one unit wanted another to switch to BLM net Tone 10. I now need to determine the Silver Peak downlink frequency for the BLM net. When I do I will monitor the northern Mono Co. traffic and try to determine the situation.

I've also heard of some changes, once again, of frequencies for the Central California District (CND) of the BLM (formerly Bakersfield District), the Mother Lode Field Office of the same District, and several for the Northern California District (NOD). There are some major changes to the Lassen National Park system as well. That's is all I've heard, but I don't have frequencies yet.
