Mark Twain National Forest (MO) updated frequencies

[scanman1958]

I have a print out of the MTNF frequency guide from 2011. I got it online with a Google search some years ago. I recently tried to get an updated frequency guide online but the only list I found was the 2011 list. Is there another more recent list out there that I can find that isn't on a "secure" site? I do know the database has a lot of good info but some of it is still a little old.

I recently received forest service traffic on a 173.xxxx P25 frequency which caught my attention. Any help would be appreciated. Thanks.

A lot of national forests have wiki articles. I don't know how accurate this is.

US Forest Service - Mark Twain National Forest (MO) - The RadioReference Wiki

wiki.radioreference.com

If you post the frequency and NAC or PL maybe somebody can identify it.

 

[scanman1958]

OK. The frequency is 173.7625. It is P25. I do not have a NAC code.

What I heard was, "Battalion 31 on Roby... Battalion 31 and Eng 682 are enroute to Stearn??? Mtn, fire to check on it's status".

I know that Roby is the name of a repeater tower within the Mark Twain Forest. I believe the units were responding from the national forest base/office in Rolla, MO.

The info that I have, that I printed out from the internet some years ago, has information on the Roby repeater. The list of frequencies I have do not include digital (P25). And there are no frequencies in the 173.xxxx range. So, I am guessing there is a new listing with updated frequencies that still may incorporate some of the old frequencies.

My main interest is getting the frequencies from "the horses mouth" sort of, like before. The listings I have include local frequencies for local and regional fire districts and police channels throughout Missouri within the borders of the park that are programmed into the parks radios. I was hoping the same kind of listing that I have, directly from the national park service, would have been updated and put online also partially because it has been over 12 years since the last info was posted.

Thanks for your help and thanks for the link.

Written in 2014-2015 based on Publicly Available data, based on the NTIA Changes occurring the Site maybe correct the I would BET the frequencies are changing around

What Make/Model Scanner are you using, most (not all) will Display the NAC's

As for Horses Mouth, those sources have widely been closing up (FOUO) and are hard to come-by now
What info did the NPS publicly share ??? URL ??

 

[scanman1958]

The scanners I am using are the 396XT and SDS100. I did not see the NAC because, at the time, I wasn't looking for it.

Here is the URL.

https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5409055.pdf

I figured that now days certain items we used to get easily are harder to come by.

OK, you said NPS,
but that is the link to the old USFS document we used to create the wiki - Nothing newer out there, nor likely will ever be

 

[scanman1958]

I just checked the frequencies of the Fire Zone 1 Mobile Radios and every channel name and frequency is the same as the updated link you gave me. I have not checked the other fire zones but I could assume that they will be the same also.

In the area of Mark Twain National Forest many towns and counties have upgraded to the MO statewide trunking system (MOSWIN) of NXDN and DMR. So I would also think it would be an huge job to try and get all those new frequencies in the forest service radios.

I quickly tried looking at the NIRSC list of frequencies but, if printed, would actually be a small book. I will look them over when I have more time.

 

[scanman1958]

And sorry to give the wrong info. I was referring to the USFS the whole time.

You mention "the park" and the "national park service," which have nothing to do with the Mark Twain National Forest nor the U.S. Forest Service which administers the Mark Twain NF. I'm confused as to what you are looking for as a result.

Edit: oops, I see you corrected that.

Trunking, NXDN and DMR will not go into U.S. Forest Service radios. A separate radio with those capabilities has to be purchased for installation. Sometimes these systems will have a talkgroup that links the USFS frequency (cies) so that agencies don't have to purchase radios of a different agency. Sometimes law enforcement officers will be provided a radio of the local and state agencies. This can be essential for interfacing with state/local law enforcement agencies. Sometimes, depending on the region, all running of 10-28's and 10-29's is done using state/local agency dispatchers. In fire management, division chiefs may have a state/local radio installed if local fire is not on VHF High. Quite often local fire departments may be on a trunked system, but have a VHF High radio in all apparatus as interoperability in wildland fire is on VHF High and won't be changing for the foreseeable future.

I think he meant to write "or" instead "of".

Our local nation forests most assuredly utilize trunking, having talkgroups on our statewide system in addition to their own VHF P25 forest nets and simplex stuff, utilizing USFS-owned Moto and BK radios.

I'm willing to bet that not all vehicles on a National Forest have a statewide trunking radio in them. Divisions and maybe battalion chiefs and Law Enforcement Officers yes. Wildlife biologists, archeologists, recreation management and the like probably have no access to a statewide trunking system and probably are happy with that.

 

[Wilrobnson]

The few that I've seen in vehicles as well as at one of their "seed orchards" do. Recreation management wise, I'm not certain.

I know the NPS rangers, lifeguards, boats and various interpretive rangers all do, but unknown re: USFS.

Why would they be happy NOT to have access??

Wildlife biologists, archaeologists, soil scientists and similar are not that interested in radio communications, they are more narrowly focused on their jobs/professions. Radio communications don't affect their jobs as much as law enforcement and such. It is hard to drag them into a basic radio training presentation. This opinion is based on my years in the USFS.

I'm surprised that there are that many trunked radios in vehicles. Someone has too much money, be that the state or the USFS.

Well here, in the land of tornadic/straight-line wind devastation and the occasional Cat-5 hurricane, community participation and frequent ICS/disaster prep trainings, things are different.

That's an...interesting...take that I can't wrap my head around at this time.

Try 173.7625 is the rptr out with an input of 165.225 and then try 172.4 rptr out with an input of 163.375, from a friend who worked A/D on travel there.

Mark Twain gets two thumbs up for eclipse viewing

I've been travelling with my SDS200/ProScan set up to trap as much traffic as possible with digital search enabled. I'm pretty sure that they've either retired or upgraded all of their previous NFM repeaters and switched over to P25 repeaters. They don't appear to be trunked to me, from what I've seen at least. I've been mapping out things and sending updates to RR every time I log/identify a new NAC but there's a lot to do for sure. I'd love it if anybody else that lives closer to one of the areas by the repeaters (the footprint of each machine is located at the bottom of that USFS link above) and help map/update RR. I'm doing my part when I travel and camp, but I live West of St Louis so probably will only be able to hear one or two repeaters using my main vertical from here. If anybody here lives in the areas by their repeaters, would you consider monitoring with digital search enabled and updating RR with whatever you find? TIA!
