New trunked system in Gunnison?

ErikB · #1 (**permalink**) 10-21-2005, 11:23 PM

Hello all-
I was hoping to get some input on a mysterious, what i belive to be trunked system in Gunnison. According to RR, the only trunked systems in the county are:

Crested Butte Resort (in use but not in close enough to listen to in Gunnison)
Holy Cross Energy (I have never heard any traffic on any of their freqs)
State of ColoradoProject 25. (Broadcasting, but not yet in use, not to mention digital)

I have been finding traffic on
0857.1625
0865.9625
0866.3625
0866.5625
None of these freqs are registered (as far as I can tell) in the county.
Typically you hear a sound like someone is keying up briefly exactally every 10 seconds and occasionally you hear what sounds like morse code. I am guessing this is a repeater identifying itself. Occasionally I hear parts of (analog) conversations on these freqs.
Today I set up my 246T to monitor these freqs as a LT system and let it do an ID search for TG tags all day long. It came up with the following:
0-01-150
0-06-079
0-20-009
0-31-179
1-09-208
1-17-007
1-17-008
My question(s) are:
Does this sound like a Trunked system?. Untill I discovered this, there were no Trunked systems to listen to within city limits so I am not sure what to look for.
Do all of the tags I found look like they are from the same system? And am I on track thinking this is a LT system?
All right, enough questions for now. Thanks in advance for any help.

Sorry I can't answer your question, but it's got me intrigued. What county are you in? Also, what is a LT system? Did you mean LTR? I'm sure when the smart people wake up & read your post, they will help.

I am in Gunnison county. Yes, I meant LTR, or logic system, but I have no idea if I am right. I have been scanning for 15 years, but never have had a trunked system to listen to so I have no idea.

Erik, Have you checked FCC database? The first two frequencies you list are licensed to Nextel and the 2nd two to the state of colorado in Salida and Montrose with PF (public safety) maybe the first two have been taken over by public safety in the rebanding move.

Upon further research and considering in Gunnison, you can hear Storm King, Cupola and Monarch on the air. You might even hear Saguache Peak and Raspberry. I bet these are State DTRS frequencies.

Last time I logged it Site 244 (Cupola Hill) was only showing 2 channels but I logged Site 210 (Storm King) last week and it was showing 5 channels including the control channel.

OK I FOUND both your 866.xxxx frequencies there are associated with site 220 (Monarch Pass).

Do you have a Pro-96 and do you log via pro96com software? If so it would be interesting to see the logs.

Jim-
I have dug around on the FCC data bases a bit.
The first two freqs I listed seem to have similar traffic and I am near certian they are the same system. The last two I found while searching the same day, basically stalking towers using CC. All 4 came up on a close call search and store. I kind of just assumed that they were related b/c the freqs all ended in the same last 3 digits. In addition to the firt two being licensed to nextel (who has no service in gunnison as far as I can tell) the freq is also licensed to Two Way Communications in Grand county. I happen to know wh have some two way towers locally, I suspect they are responsible for the system. All traffic I have heard sounds like businesses, ie. a gravel quarry, Tow truck, salvage yard, etc....
Thanks for looking into this for me Jim, anyone else have any ideas? All input is appreciated.

Wow, sweet! SO the 2 866.xxx freqs are DTRS, cool. My house is less than a mile from the Cupola tower. Thanks Jim!
I am not sure what to make of the traffic on the first two freqs, they are analog and definitely not the state. I know 2 way has business LTR trunked system in grand county, I wonder if they are extending it up here. The TG tags I have logged are different than the ones listed in RR for the system.
See link:
http://www.radioreference.com/module...TRSDB&sid=3804
This would account for 857.1625, but not 865.9625, maybe two new systems and I need to scan more for more freqs?
What should I do next to try to nail this system down?

Again, here are the tags I logged on these freqs.
0-01-150
0-06-079
0-20-009
0-31-179
1-09-208
1-17-007
1-17-008

The only trunking scanner I own is my Uniden 246T

jimmnn · #10 (**permalink**) 10-22-2005, 04:47 PM

I still think those first two freqs are Nextel (Nexthell).

Do we know if those id's you are logging are voice or my bet would be data?

Do you have a DTRS radio to log the sites?

I have no idea whether they are voice or data. I only seem to hear voice during business hours mon-fri. Been listening all day and nothing out of those freqs now. I have nothing with DTRS capabilities.
Thanks for the help/input.

I was just looking at the Nextal site and searched out what the coverage was in my area. A search for my zip yielded:
"We're sorry, but the Nextel National Network does not currently offer coverage in the area you entered, 81230. Please enter another ZIP Code or check back again in the future. Coverage within this area may be available on the Nationwide Sprint PCS Network through the use of Sprint PCS products and services.* Learn more"
I know people with nextel phones that cannot get them to work in Gunnison.

I know they have DTRS in the area. in '02 I was working the Hells Angel rally and was actually talking to Denver when I got there, then we used ITAC 1 everynow and then while we were up there.

Yes DTRS is currently live and active thruout his area but not frequently used yet.

Here is an example of what you hear on 857.1625 when there is no voice transmission going on, which is most of the time. It repeats itself every 10 seconds. Occasionally you hear what sounds to me like morse code. 865.9625 sounds the same.

letarotor · #16 (**permalink**) 09-08-2007, 05:02 AM

Eric,

Definately sounds like an LTR chirp to me. We have a bunch of LTR systems here in the Dallas/Fort Worth area. I use a PRO-97 to snoop them out because of the LTR home channel decoding feature on this scanner. LTR licencing is hit and miss, as most companies that set up LTR systems don't want them monitored so they will get licences under another name, combine licences or in some cases swap frequencies. I was in Breckenridge two summers ago and discovered a 450 MHz LTR system being used by one of the resorts. Just checked the freqs again on the FCC database: no licence. So could someone in Gunnison have a LTR system set up using 857.1625, quite possibly. I'm not familiar with the BC246, and if it has LTR decoding capability. You seem to be getting a bunch of iterinent area codes (1st number), home channels (2nd number) and talkgroups (3rd number), and any that display a home channel over 20 would be incorrect. However, whenever the morse code identifier comes up it should display talkgroup 255 (the last talkgroup available on a conventional LTR system). I believe only the PRO-97/2055 have the decoding capability. If you can get your hands on a PRO-97 (they are on close-out sale at RS now), put in the frequency and see what the scanner tells you. If an active talkgroup pops up it will display it, and at the right an "R" followed by the actual home channel will be displayed.

Eric,

I also forgot to mention that sometimes the PRO-97 will display the area code, home channel and talkgroup momentarily during each 8 to 10 second repeater keyup. Doesn't work all the time, and on some systems, no matter how close you get, it won't display any numbers until someone transmits on the system, or the morse code identifier keys up. Once you get the proper LCN positions for the home channels, then they can be programmed into a bank and scanned as a regular trunked system, thus eliminating having to listen to the key up every 10 seconds.
