I am sure I am missing something, so hopefully someone can help me figure it out. I had this same scanner 10 years ago. Worked great. Just got one again. (yes it also has the P25 card, like my other one did). I have selected one site for frequencies, and the talkgroups I want from the selections in the ARMER trunked system (for Minnesota). Upload to the scanner, but it only scans the frequencies, not the talk groups. I have tried to put it in ID scan mode. No luck. Ideas on where to start sorting this mess?

It sounds like you did one of two things possibly.

1. You didn't program the radio system as a trunked radio system? Did you program it as a trunk system or did you just enter the frequencies like you would any other conventional frequency?

The other option is that you possibly have not enabled the trunking option on that specific bank in your scanner. You have to hit that trunk button when the scanner is scanning on the bank you have the TRS programmed into. You can't hit it while it's scanning a bank of conventional frequencies and have it turn on for the bank that you want to scan the system on. It takes real quick action sometimes to do that and you may have to turn off the other banks that are not trunk systems in order to just have that one bank that has your TRS scanning at the time. And then you can hit the TRUNK button to turn it on and off. If it's off it will just scan the frequencies like any other conventional frequency.

I have mine programmed With nothing but military aviation frequencies now and it's been probably a decade or more since I programmed anything in that is a TRS. So I'm a little rusty on telling you how to do it step by step right now. But there should be a button on there that says something like TRUNK. I'm looking at the front of mine right now, and mine is a BCD796D. The card is built into it for digital as far as I know. But if you look to the right of the screen and you look down to the fourth button to the right of the screen, again looking down and not across, you'll see the TRUNK button. But you do have to program the frequencies in as a trunk system for whatever type of TRS you are trying to monitor. Whether it's a Motorola Type 2, EDACS, LTR, etc it has to be programmed in the trunk mode. You cannot just put the frequencies in and then use that trunk button.

Just looking at mine right now, you hit the MENU button, then you pick the second option which is 2. SCAN OPTION, And then you pick two again which says TRUNK. There it will take you to the first channel of whichever bank you're currently on and you can program in frequency 1, move up and program in frequency 2, and then so on.

Also look through the menu I believe under , the third option when you first hit the menu button, and then go down to the last option which is number 10 even though it says 0. Just be sure that the P25 card is turned on if it's a digital system. I don't know anything about the system you're talking about programming but be sure it's one that can be programmed into this radio. These radios came out before the rebanding and I don't believe you can add any 700 MHz frequencies in them.

Like I said, it's been a while since I've put any kind of trunking programming into mine and I'm rusty on it myself. But hopefully some of that will help you if it's a system that this scanner is capable of trunk tracking. Good luck!

I'm legally blind and I'm about to go to bed so I can't go back and really proofread this whole message and make sure Google typed everything right. But I did make sure to make the options on the radio in bold so as to hopefully make it easier to read this and then look and find what I was describing. Goodnight :)

Do you have ARC250 software. If you do, please attach your programming file and I will check it for problems. You will need to right click on the file and Send to Compressed (zipped) folder to be able to attach it. Click on Attach files and Open the zipped folder. I also have ProScan. You can attach a ProScan file directly without needing to zip it.

Ok, thanks guys. @letarotor like I said, mine has the P25 card. Latest rebanding firmware, trying to scan an 800 Mhz P25 phase 1 system. I will try to check the options and see if I missed something. I used ProScan to program, so it put the frequencies and the talk groups in the scanner for me. @tvengr I would sure appreciate that. I like to keep the different agancies split so I can toggle areas I'm not interested in listening to. Just so you have an idea what I have going on. The channel frequencies that are in there are for the closest site to my primary listening location. The system is the ARMER system, a Motorola Type 2 P25 and covers MN and some ND I think?

The Trunk Type is Off. Go to the Trunk Bank Settings and change Bank 1 to "MOTOROLA TYPE 2 / P25 800" like the image then upload.

I turned it on as shown, no difference. still scanning the channels, not the talkgroups.
Did you Upload with the option 'Trunk Bank Settings' set and the 'Starting Trunk Bank' set to 1?

Did not work either. I have done everything you guys have suggested. I've double checked things. I can not get this thing to scan the talk groups.

What site do you have programmed? You don't have any of the control channels for Ramsey or Hennepin Counties. The scanner will not work without the proper frequencies. The 796 will allow only one site per bank.

Give this Ramsey County file a try. It has Ramsey Co Fire/Sheriff, St Paul Fire/Police, and MN State Patrol. It does not include local fire or police. Save the attached zipped file to your computer and extract. Open the extracted file with ProScan, and Upload to your scanner.

Did some more checking. You have no control channels for Washington, Dakota, or Anoka Counties either. The frequencies you have are nowhere near to your location.

Ok, I uploaded the codeplug you sent. Now I at least see it stopping on ID's occasionally. Sometimes I get some audio. I will listen for a while and see what happens. Still surprised at the lack of activity between 3 different agencies. Seems I used to hear a lot more in years past. To add "sites" I need to do that in different banks, correct? So if I use my scanner mobile and am out of range of the Ramsey County site, I would have to add one for the area I'm in?

If you are having problems receiving, it is probably due to simulcast distortion. With simulcast systems, you will find that the scanner may work properly only in certain locations. Simulcast distortion is very location specific. Although Ramsey County is shown as a single site, it consists of multiple towers all transmitting on the same frequency at the same time. The signals arrive at your scanner at slightly different times, impairing its ability to properly decode the control channel. Try moving the scanner around, reorienting the antenna, and turning on the attenuator. The only scanners designed to receive simulcast systems are the Uniden SDS100 handheld and SDS200 base/mobile. If you travel, you will need the control channel and alternate frequencies of a site in your area. Each one will need to be set up in a different bank, along with the appropriate talkgroups..
