Digital scanners are often expensive. Worse for you, they are also often encrypted.
So it would be pointless to get one?
Radio Reference Forums would have more info on your area.
broadcastify is great if someone already has a scanner set up.
I would try to find out the encryption status of your local area before sinking any money into one. Something like radioreference.com may answer that question.
Check Radio Reference and look for the "E's". If you don't see any or many on the systems you are wanting to monitor...you should be fine.
I love my SDS100. It's definitely not pointless for me.
Full encryption is quite rare these days. It pays to research the area you are looking at monitoring (i.e. check radio reference).
On iOS, I use the 5-0 Radio app. Has most of my local LE organizations. Won't do encrypted but works well for me. I've also played with a SDR dongle and was able to record some local LE but getting it to output real time audio was a hack and not as good as the app. Plus the app was free.
The problem with the app is that it isn't always real time. For example, Wise County (in Texas) feed has a 15 minute delay on it.
The 5-0 app actually doesn't care if the audio is encrypted or not...it's dependent on a receiver in the coverage area providing a feed. If that receiver can decrypt the communications...then it will pass the decrypted audio over the feed.
15 min delay is fine, i spend a lot of time driving and just want to see what going on on the interstate
I will try the app until I get something set up. Thank you
What's your budget?
Do you know if they are using P2 Trunked?
If so, either would do and is close to your budget
For HT: Uniden BCD325P2 Phase II
Mobile/Desk: BCD996P2 Phase II Base/Mobile Digital Scanner
Although more work to get setup, try an SDR dongle .
What makes it more work to get set up? Just the software? Definitely not as portable as a handheld scanner but definitely should work just fine if unencrypted.
I guess more work is relative... with some Uniden scanners, you turn it on and plug in your zip code and are scanning. With a SDR, you might have to fiddle with drivers, there are different applications that you can use, so picking the right one might involve some research.
Oh that’s fair. It was posted on ham radio subreddit so I didn’t figure spending hours messing with drivers and plugging in some memories was enough to consider it more work haha. That just sounds like a Sunday morning!
I didn’t actually realize you could use an sdr to decode p25 tho... I might need an sdr now... my police and fire just went p25 (unencrypted)
You need 2 dongles for trunked signals
Interesting. Why is that?
From what I understand one dongle is used to "detrunk" the signal and the other one is used the normal way after the first "detrunks" the signal. There are youtube videos that explain the process much better than me.
A single rtl-sdr's bandwidth is usually too small to receive the full range used by a trunked system. Other SDRs like a hacked or airspy r2 don't have this problem.
Ohh so external programs would stitch the two together to expand the bandwidth. That makes sense. Now I’ll need to look into this before buying one to make sure it’s covered...
LULZ!!! You have a bunch of posts about lock picks and now are asking about a police scanner.... looks pretty sus
If you want to be a criminal use a computer, it's much less risk and more lucrative ; )
On the surface that is pretty sus, but I do know a fair number of people into radio/computers/locksport that don't have any criminal intent. Well usually no criminal intent beyond breaking prohibition laws, that's pretty common.
My parents were into CB’s and scanners, that’s how I got into that and lock pick lawyers is why I got picks.
The difference between a wolf and a big dog is only what they do with what they got..... I don’t blame you for being interested in different things.
sdr usb stick and a program called sdrtruck.
If you go the SDR route, be a bro and go ahead and stream it to broadcastify
Broadcastify has some of my local stuff with little delay
I’m fine with a delay, thank you
Try using a SDR Receiver. Most of these cover from 25Mhz to 2Ghz and some like the RSplay cover .1Khz to 2Ghz. There is software that will turn your SDR into a scanner. Check YouTube there are all kinds of videos on this subject. A good digital Trunking Scanner like the Uniden BCD436HP, which I have are selling at $499.99, if you can still find one. They have been replaced with a newer model. A good digital scanner will cost you some $$$. If you buy a good one to began with you will be happier than if you purchase a cheap piece of s\_ \_t. To get started I would suggest you get one of the RTLSDR Dongles for $25.00 off of Amazon and hook a good antenna to it. Download the scanner software and give that a try first to see if you want to invest in a good scanner. A lot of the cops in certain areas the data is encrypted, and even those there is a way to decrypted it, I would not suggest doing that. Lots of the smaller towns and counties are still open depending on where you live. I would also suggest you check Radio Reference to see what is active in your area of interest for the Public Serivce.
[Trunk -recorder](https://github.com/robotastic/trunk-recorder) and 2 or 3 RTL-SDR's will work well for P25 and analog trunked systems.
[Rdio Scanner](https://github.com/chuot/rdio-scanner) is a good web interface for trunk-recorder that will let you stream the audio over the internet.
