I got asked this question a couple times when mentioning that I always have the police radio playing at home.
There are a lot of (totally legal!) ways to listen in on your local gang in blue’s radio communications, but the easiest is to use Broadcastify.com, a service run by RadioReference (awesome boomer RF resource). It’s free, works pretty well, and is so easy to get running that your ACAB grandma could figure it out.
Click your state, scroll or Ctrl+F for your locality, then click play. Police channels, fire channels, public safety, etc.
If the department you’re looking for isn’t listed it may be for a couple reasons. If they’re using encryption in addition to just digital trunking, then it’s unlikely anyone will be streaming them to Broadcastify. But if they don’t use encryption (and you can use RadioReference to look up what system every PD is using!) it may just be that no one is currently streaming that specific PD. Maybe it’s a really small town, or maybe the person streaming it before is under arrest lmao.
Which is actually excellent, because now you can learn about RTL-SDR and start capturing their radio yourself! Gone are the days when you need to drop $500 on a police scanner just to handle trunking. You can spend less than $30 on an RTL-SDR dongle and couple that with free software. The actual set-up is beyond the scope of this quick post, but there are a lot of articles out there on how to do it, and it’s really fun.
I will note that some departments are moving towards encrypted real time communications and then time delayed text transcripts. This is under the guise of “officer safety” but really they hate the fact that civilians were actively monitoring them and calling out possible issues in real time on the bird site and other social media.
Yep! So at this past Def Con, sally who makes yachts gave a really good presentation that touched on this. Even with voice encryption, the amount of information you can get from just the meta data is incredibly useful.
I lack the technical knowledge to add anything meaningful to this conversation, but sally who makes yachts is a damned cool non de plume.
That was my first thought when I saw the talk come up!!
