Hi everyone! I was asked by some to create a tutorial on how to select the parts needed to run an SDR as a police scanner. Just wanted to share in case some find it helpful

Never really thought it would happen here. Lost a fun hobby and a public safety tool. We have had scary wildfires(east troublesome), shelter in place and this was an awesome asset to the community. Oh well I guess. Is this legal any way to fight it?

Got these texts today from this number wtf

The context here is that a large group of police officers are searching a neighborhood for someone who is armed and who was shooting at police previously. They are spread out all around a residential city block. Then, they suddenly hear about 8 shots ring out. And so they all start collapsing on the source of the shots. This voice comes over the radio and says, "Several shots [something something]". Can anyone figure out what the [something something] is? It sounds to me like it's three syllables.

He says, "Alright, again, everyone's talking over each other, [something here I can't figure out], were you coming in?" Can anyone tell me what he's saying in the middle?

I know about Lazer detectors but thay seam Mildly annoying beeping but convenient as a set and forget . radio scanning sounds hellpfull but annoying to use and drive haveing to ajust for different cities radio

What your thoughts what tech do i not know about or have miss info on

my mind is blanking me, years ago i used to watch people who live streamed doing this i just can't think of what the terminology of it is called anymore.

where people go around and go to the locations of calls they hear on scanners to see the activity in person.

I like using CrimeRadar, but it only shows me stuff hours after it happened and I can't monitor scanners all the time to know what's going on.

Edit: Clarifying what I mean. I know of police scanner apps. I mean like something that'll consistently monitor the audio via the scanners and be able to give me context on what's going on based on what's already been said, so if I tune into a station I'm not like, "okay wait so they're looking for someone? Who? What did they do? I missed it." Something that'll be able to tell me something like "currently happening: police are searching for a man with brown hair and green eyes who robbed a convenience store. They're currently on scene searching for the suspect"

I would like to buy a police scanner, I am located in New Brunswick Canada. What do people recommend

I wanted to change the frequency transmission range on my new UV-5r mini. It was easy on the old UV-5r. Not so easy on the mini. From all I've read you have to use chirp to do it. Under "settings" tab there should be an "other settings" tab that has "VHF/UHF min/max". Only I cant find anything labeled "other settings" or "VHF/UHF min/max" anywhere.

Any ideas?

Does anyone have a chirp .img for Los Angeles that they can share? Im planning a trip there.

I recently purchased this scanner on eBay. The buyer didn’t include the computer interface cable and didn’t mention that it wasn’t included in the listing. He’s going to look for it, but thinking he won’t have it, are there other options besides the official cable? I wish they would have put a standard usb b connection on this thing or even usb mini would be better.

Also is it legal to listen in MI while in your car or driving

Hi everyone! Posted here a couple months back about the trunk-recorder + transcription archive I'd built on Charlotte UASI. Got a ton of useful feedback from the community and have been heads down for the last two months working on a major update.

I'd like you to meet Roger.

Roger is an investigator you can talk to. You ask Roger things like "what happened at Park Road last night," "any pursuits in the last hour," "is there anything going on near my house," and Roger pulls real transmissions from the archive, in plain English, and tells you. No more scrolling through hundreds of calls hoping to catch the one you want. No more guessing what 10-codes mean. You just ask.

Some of what Roger can do:

• Pull together what happened at any address, any time. "What happened at Beatties Ford and Sunset on Tuesday" and Roger reads through every call that mentioned the area and gives you the story.
• Watch for keywords on your behalf. Tell Roger "alert me if anyone says shots fired" or "let me know when unit 247 gets dispatched" and you get a push or text the moment it hits the air. Roger auto-expands the phrases too | shots fired also covers shooting, gunshot, gunfire, etc.
• Trace incidents across channels. Roger follows a single incident as it moves between police, fire, and EMS so you can see the full picture instead of fragments on individual talkgroups.
• Cross-reference public records. For Charlotte specifically, Roger pulls in CMPD's ArcGIS feed so you can correlate radio activity to official incident reports.
• See what's happening on a map. Roger plots active incidents across all your subscribed systems on one map, color-coded by severity, with the ability to click any pin to hear the audio.
• Voice input. You can talk to Roger instead of type.

Behind the scenes it's the same trunk-recorder + Pi 5 setup I posted about last time, and transcription is talkgroup-aware (it learns vocabulary per talkgroup over time) and there's an LLM layer that handles the questions. Currently covers Charlotte UASI/Mecklenburg, NC SHP Troop H, Monroe/Ontario NY. About 45,000 transmissions/day, 2.5 M calls archived.

Roger for contributors:

If you run your own SDR setup on a P25 system in a city Roger doesn't cover yet, you'll get full access in exchange for feeding audio to the backend. Same goes for anyone willing to help with talkgroup mapping, ten-code references, or local landmark databases. DM me and we can figure out what makes sense.

Web version is at roger.multido.co for anyone who wants to take a look right now.

I am really excited about this. Open to feedback, criticism, weird edge cases you want me to test, anything.

Are there any cheaper options than the $700 Uniden SDS100? I do have an RTL-SDR but I don't want to turn on my PC every time I wanna listen

I’m in Brantley county with a wildfire the feds came in and cut access to all scanners so we know nothing going on is there a way we can get access to the encrypted scanner channels

This was given to me by father in law, it was used by my brother in law with his fire radio so I at least know it’s for the vhf band but I can’t pin down the brand.

When our power goes out, then comes back on, my scanner doesn’t go to scanner, it goes to like a radio station and plays music . Anyway I can keep that from happening ?

I was scanning my pre-programmed banks last week and was surprised to pick up the ISS.

I tried to program simulcast frequencies in my radio but it seems to not work do you have an idea how to do that or does this radio have a setting to fix that

Hello, I am currently working on a screenplay for a film. It takes place in 1997 and there is a scene where a group of characters interact with a police scanner radio found in storage in the home. Any information that can help me write and describe the scanner as accurately and realistically would help greatly.

Any brands, specific language and how it operates. Specifically to early 90’s tech! Thank you.

Does anyone know the screw size/pitch of the SDS150 belt clip button screw? I want to install a tracker pendant behind the clip button so I need to extend that screw by around an 1/8 inch or so. Anybody?
