rdio-scanner VS radiocapture-rf

If your area is P25, then https://github.com/robotastic/trunk-recorder with https://github.com/chuot/rdio-scanner makes a great setup.

This is the answer. I use this program and it works great. May also want to get https://github.com/chuot/rdio-scanner as this will let you pick and choose which of the monitored talkgroups to listen to, queue up the messages so you're not hearing a bunch of stuff at the same time (or missing things altogether), and lets you go back in time. It also has a great mobile app that you can setup if you want to listen when away from your PC.

trunk-recorder can do this https://github.com/robotastic/trunk-recorder while originally designed for trunked systems, it can handle conventional systems as well. Which pairs nicely with https://github.com/chuot/rdio-scanner which provides a nice web/phone app interface to listen to, that includes the ability go back thru a call archive.

Then use this as a front end with trunk-recorder. Both are in docker images and run 24/7 no issues.

https://github.com/chuot/rdio-scanner is a great alternative if you don't want to stream to one of the public options and it has a plugin for trunk-recorder and a mobile web app.

You can use Trunk Recorder to record signals and RDIO Scanner to play them as they are captured. That will only work if they are all in the passband of the SDR, but you can use more than one SDR with it.

Trunk -recorder and 2 or 3 RTL-SDR's will work well for P25 and analog trunked systems. Rdio Scanner is a good web interface for trunk-recorder that will let you stream the audio over the internet.

I have something that does basically what you're talking about, in a fairly simplistic way, here https://github.com/MattMills/radiocapture-rf/blob/master/fft_based_scan.sh
