Un-wanted chatter! help

[nuge16]

So I’m having a problem with my scanner. I have programmed a frequency for my area, Gaylord Michigan. The frequency is 866.88750: The local Sheriff Department, City Police Office, and State police post use this frequency. I also have unwanted chatter from some business talking about programming boxes in telephone poles (or something); most of the time it is encrypted. Is there a way I can ignore the unwanted chatter from that frequency? I can’t L/OUT or else I lose the police. I am unfamiliar with trunking so I don’t know if that has anything to do with this.

Any help would be appreciated! I hate hearing alien sounds while driving (encryption).

Is it a trunked frequency or is it a conventional frequency? If it is a voice channel on a trunked system you need to program the control channels and the talkgroups.

I’m assuming it is trunked, since multiple users are on the same frequency. The police use 866.88750 as their main, but once someone else talks, they move to different frequencies (which I have). Once the main one is active though, I can’t seem to pick up the other frequencies.

I’m not trunking genius.

The frequency you listed is on the MPSCS system, this is a digital trunked system. For Gaylord it is site 433. You need to program your scanner for a Mot P25 system and pick which TG's you want. Scanning one voice channel on a trunked system won't get you much.
What type of scanner do you have?

I have a RadioShack Pro-96 Digital Trunking Handheld. You spook me out by saying all those numbers and programming. I’m at work right now so I have the time if you can point me to a guide.

The easiest way to program a PRO-96 is with software, download Win96 and get the programing cable from Radio Shack. This is the system I'm talking about
http://www.radioreference.com/modules.php?name=TRSDB&sid=100
The first part is the Towers or sites with their Freqs, the PRO-96 only needs the control channel and not the voice freqs. I'm not very good at programing the PRO-96 by hand, I do mine with WIN96. Program 868.8875 in the scanner as MOT and the bank as MOT also. Then program the talkgroups you want. For more information on WIN96 see the WIKI above or go here:

Would the talk groups be the Police and all their frequencies? I have the radio shack USB connecter so once I get home I can mess with that and see where I go.

Thanks.

The Control Channel would be 868.88750.

The talkgroups would be like this:

Mutual Aid/Intersystem Talkgroups

DEC HEX Mode Display Description
432 1b0 D MEPSS PAT Patched to 155.865 MHz., in the U.P.
1455 5af D MEPSS1 Statewide Emergency 1
1456 5b0 D MEPSS2 Statewide Emergency 2

The only thing you really need to pay attention to is DEC which stands for decimal. These are what you will use to program your scanner with.

The only freq you need is the control channel (868.8875), the radio will get the voice channels from the control channel, the talk groups are:
Otsego County (69) Talkgroups []

DEC HEX Mode Display Description
5021 139d D 69DRUG County Narcotics Enforcement Common
5027 13a3 D 69P911 Central 9-1-1 Police - Dispatch
5031 13a7 D 69COM Countywide COM (Mutual Aid all agencies)
5032 13a8 D 69LEIN LEIN
5039 13af D 69E911 EMS - Car-to-Car
5040 13b0 D 69F911 Central 9-1-1 Fire - Admin.
5042 13b2 D 69PD169 Sheriff - Car-to-Car
5043 13b3 D 69PD421 Gaylord Police - Ops
You only need the dec. values.

If you download Win96 here's a file to get you started.

Ok, I have the 30 day version of WIN96. I am at the channels tab but I dont know where to input the information you gave me. The info sounds right, with LEIN and p911 but getting it on my scanner is a different story.

 

[nuge16]

I get a lot of encrypted crap on the main frequency. Is there a way around that certian encryption?

If you have the bank set as MOT and the freq set as MOT and set the scanner to scan it should sit quietly on the control channel untill there is a transmission, Encrypted messages sounds like R2D2 and the PRO96 should not pick them up unless you're not scanninng Trunked. Did you load the file I sent? If you're hitting MAN on the Control Channel you'll hear the CC noise, which is 9600 baud Data. If you hit MAN on the CC and get the data sound there should be a % number in the bottom right corner, this is the CC decode percent, if it's below 70% you don't have a good signal.

Yes I loaded the file into my scanner. I want to surf mainly the 69LEIN and EMS/Fire channels. I think I have figured it out, but not 100%. When I hit MAN and go to the GAYLORD freq (first one) I hear a sound like a diesel engine running. Is that normal?

That's the CC's sound. If you only want certain TG, put just them in and put the bank in the closed mode by checking the Closed box next to the bank name and if you want to lockout certain Talkgroups just check the lockout box next to the talkgraup alpha tag and upload it to the scanner. If you don't want the other freqs I put in the file just delete them and upload.
