Bartholomew county highway indiana is not on 151.085 now, how can I locate this system?

Why do you think they're not?

 

[cdgates]

I have listened to 151.085 and receive nothing, I have a friend that works for them, they use radio all the time, I have a idea they have moved to a trunked system of some kind, but I don't know?

Is your radio capable of receiving DMR? The database shows they're using that.

 

[cdgates]

Yes have a sds200 with the DMR upgrade. But that kind of lost me, 151.085 was a standard repeater output frequency, could that same frequency be used for DMR now? I have never programed a DMR frequency

 

[INDaviation]

Just set the audio type to Digital Code Search and see if that helps.

 

[cdgates]

Ok

Have you done an ID Search on either SAFE-T or Columbus Public Safety (P25)?

 

[cdgates]

Yes, I can't find it anywhere, I even asked the people that service the system, they only told me that it was a single frequency that was in the Columbus system, and would not tell me anymore. At one time I sold radios into the repeater systen, I don't know what the big secret is, I would like to listen when we have large snow like we do now.

In your scanner, program 151.085 as an analog FM channel with no PL tone. If you hear digital/computer noise then you somebody is operating DMR on that frequency. It could be County Highway, or it could be your Sheriff's Dept.

First you have to figure out if there is radio traffic on that frequency, then you can figure out how to decode it.

I hear no siginal of any kind on 151.085, i.have plugged. It into two scanners and i.hear nothing. It's only my guess that when the county went to trunking the highway dept is in some way in the mix of things.

Did you program your scanners by hand, or did you program via Radio Reference?

Edit: The information on Radio Reference is not complete. You're not going to hear anything if you are programming your scanner with software that gets its data from Radio Reference.

I did most of the programing through RR WITH SANTINEL softwear, I had a friend that has a 200, he did most of the programming at first, he could not find BARTHILOMEW COUNTY HIGHWAY himself, i have been trying to find it for about six weeks, I thought if I put this out on this form I may get lucky and find someone that has found it. I was also thinking becouse I ran a two-way radios business in the past they would give me the information? Before trunking came on the market I got out of the business, I know they are using sompthing, When I seen this frequency listed as DMR it was a surprise, but I did get the DMR update from Uniden, I might note i found some frequencies listed as DMR that worked before I bought the DMR code, I have no idea how DMR works and if it's in someway mixed up in a trunking system. When I sold radios, the 151.085 repeater was used at night sometimes by the sheriff dept and also used by other county people, like code enforcement, and other county likewise county employes.

Right. So apparently the 151.085 repeater was switched over to a DMR repeater that can be shared by many users.

The issue is: it takes more than just knowing its "DMR" to listen to it.

DMR has 3 parameters that need to be known in order to program a scanner to listen to a specific user.

You need to know the (1) Color Code, the (2) Slot, and the (3) Talkgroup number.

On the Bartholomew Co listing it shows the Sheriff's Dept using this DMR repeater utilizing a Color Code (written as: CC) of "4".

The Slot (written as: SL) is an asterisk, meaning someone did not know which Slot they operate on. There are only two options for Slot: Slot 1, or Slot 2.

The Talkgroup (written as: TG) is an asterisk, meaning someone did not know which Talkgroup they were using.

In the programming softwares, an asterisk tells the scanners to search for anything that it hears.

On the County Highway listing, it just says DMR. It doesn't list a CC, SL, or TG; and it doesn't list any asterisks either, so I'm not sure that it's even trying to search 151.085 for any DMR signal at all.

You said you're not hearing anything, but it may be that you haven't programed enough information into the scanner to even attempt to hear it.

So, you're back to square one. To verify that there is DMR radio traffic on 151.085, you can program that frequency into your scanner as an analog FM channel. If you start hearing digital/computer-type noise being transmitted on that channel, then that will tell you that there is, in fact, digital radio traffic on that frequency.

(or you could just skip to the following step)

Program in the Sheriff's Dept's DMR channel. It's the same frequency, with CC:4, and asterisks for SL and TG, meaning it'll let you hear any Slot and any Talkgroup that comes across that frequency.

If the Sheriff's Dept uses SL: 2, TG: 101..you'll hear it.

If the Highway Dept uses SL: 1, TG: 301.. You'll hear it.

If the Health Dept uses SL: 1, TG 116.. You'll hear it.

Thanks, next week I will try to find someone to help me with this, it's over my head.

 

[west-pac]

I saw that somebody added county highway to the Columbus P25 system. If you update your database from Radio Reference you will be able to select and add it to your scanner from your software.

Thanks, I just updated yesterday, i will take look later this evening.
