Most of our local departments use encrypted radios.

"Over the past few years, an increasing number of municipalities and police departments, including the District’s, have begun encrypting their radioed communications.."[1.]

You don't have to rely on app stores... Broadcastify is the platform that powers all these apps, and they are online at https://www.broadcastify.com

I remember a few apps that you could watch the towers in your area and be alerted or warned when new ones popped up. But one app needed to be trained to remember the towers in your area.

Something like this maybe? https://f-droid.org/en/packages/info.zamojski.soft.towercoll...

University of Washington researchers are working on this, their technique has used roaming car sharing vehicles and anomaly analysis:

Matt Blaze has a classic talk about crypto failures by LE using radios. In short, the feds still screw it up and accidentally operate in the clear.

I've personally heard a Stingray being used for an arrest being broadcast on an open, analog channel.

Im doing the same right now in Minneapolis. Running Hack RF and Unitrunker V2, tapped straight into Minneapolis City Center Multicast. I have a radio reference account so Unitrunker just syncs to its database and all that info auto magically appears.

Here's my live youtube stream and archives: https://www.youtube.com/watch?v=LuCP1ZetSEA

Not OP, but: many common voice encryption implementations have serious usability issues which lead to users inadvertently -- or often even intentionally -- disabling encryption

Yup, see our Broadcastify Calls Implementation

Thank you for you this! For the last couple of years, I play Broadcastify combined with one of those downbeat live channels in YouTube while I code. This after I tired of http://youarelistening.to/

>>eloran+(OP)
I haven't done the work to sign up at Broadcastify, but if you're in Durham NC and want to listen hit http://home.tinfig.com:9999 with VLC (or mplayer or whatever you like).

It's an HTTP+Ogg+Opus stream from my BCD536HP. It's scanning the local P25 trunked radio system (Durham police, fire, EMS, ops, etc.).

P.S. As I write this I'm hearing chatter about responding to an airplane crash... no more details yet.

>>autojo+ww1
I suppose maybe you can try running it through Otter[1]. We’ve used it with varying degrees of success when interviewing customers, and it’s also what powers Zoom’s transcript feature which is what we use these days.

It’s hit and miss, in my opinion. It’ll give you a good enough base to refine the transcript from, but I’ve yet to come across a transcript that doesn’t need editing. (Which is annoying, since Zoom doesn’t give you that option.) I’d say it’s more valuable having the tool than not, but don’t expect miracles.

(I’m not affiliated with Otter or Zoom in any way.)

I thought there were some open source speech-to-text models already [1].

Maybe there's something unique about how these low-quality radio transmissions sound that make these ineffective?

You may already be aware of this, but SomaFM has an ad-free version of this idea streamed 24/7. I enjoy it.

Doubtful.

I'd fully expect other exemptions to apply if you FOIAed the White House's SSL private key or something.

Indeed. The only reason I know is that I tried a few years back and realized that I was asking the computer to do something that I couldn't even do. Anyone that doubts it, just listen to the NYPD feed and try to transcribe for just a minute or two.

(edit: also, thank you for keeping this service up and running for so long, have been a regular user since the early RR days. Would love to have a comment/live chat option if your backlog is getting bare :))

Ok, here we go: https://feeds.talonvoice.com

Repo is here if you need to report (or just fix :D) bugs in the webapp: https://github.com/lunixbochs/feeds

>>autojo+ww1
It's a hard problem. I'm prototyping this here [1]. Any user can tweak or vote on transcriptions, so my goal is to use the user annotations to help train models and make it better.

If you want to help with development, reach out and I can onboard + give some test data.

This should, at least the last time I used it:

I wrote this parallel scanner. I had tried incorporating DSD, but couldn’t handle more than 2 streams. Though that was several years ago.

Oh nice!! I was listening to your platform for NYC Citywide-1 for a couple of hours last night after someone in YT chat of Louis Rossmann's security cam feed (retail store that fixes Macs in Manhattan) dropped some Broadcastify stream links.

It is helpful, but not necessary. I am listening in on Seattle's trunked radio system with just one, and I get most of the comms.

I documented my setup here: https://dantler.us/seattle-police-scanner/

>>shadow+Fu1
There are more Encrypted than you think, though most Responsible Dept will leave the general dispatch channel open and only encrypt tactical talk groups

My City Encrypts 100% communications including EMS, Fire, Police and Emergency repose, it is a stupid policy but...

I've got a year+ of the Ohio MARCS-IP site in Hamilton County Ohio recorded. Let me know if you need some data -- I'd be more than happy to get you the dump.

(trunk-recorder + rdio scanner).

The UI is:

https://cvgscan.iwdo.xyz for the live stuff, but, let me know if you're interested in the data -- my email is in my profile

>>shadow+Fu1
there are channels of police and other agencies that can be encrypted, generally of course for the police to be encrypted the local municipality needs to decide to do that and pay the bills, hence it doesn't happen - which is a good thing.

I'm thinking a traffic analysis app https://en.wikipedia.org/wiki/Traffic_analysis might be useful for when encryption becomes more widespread.

>>callal+CA1
The creator of CryptoCat was targeted by the FBI. Not because he was suspected of committing a crime, just because they didn't like him creating open source encryption software. They actually had Hector Monsegur (Sabu) try to entrap him multiple times to try and come up with some trumped up reason to convict him.

Moxie Marlinspike can't even fly domestically without jumping through hoops and travelling internationally means they try to seize his electronics and demand the passwords.

I’m Chicago, this one is much clearer and interesting scanner:

In Chicago, try this one. Much. Nicer because you can put different channels on each headphone and manage multiple feeds more easily:

Ah the bandwidth isn't something I'd considered. That's a good point. Unfortunately for me the KCERS Seattle site's total bandwidth is about 6.5 mhz. I have a RTL-SDR and a SDRPlay but it seems like the only thing that can talk to the SDRPlay is their own software.

Here is a current publication[1] that covers the rules that apply in a typical Midwest state. Page 19 covers use of artificial lights and various exceptions. There is a great deal to know and conservation officers enforce these rules enthusiastically.

That has nothing to do with it. Your mobile phone voice comms are encrypted. Push to talk over cellular is another solution which British police use.

Police are increasingly militarised, pretty much any military uses encrypted radios. It's a cheap technology now.
