timestampSDR VS trunk-recorder

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

Looks like its available for mac aswell. I think I can use this solely for listening and recording https://github.com/robotastic/trunk-recorder

I would search the issues on GitHub and possibly submit an issue if you don't find the answer that way. https://github.com/robotastic/trunk-recorder/issues

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.

I've toyed with monitoring the Portland system using GitHub - robotastic/trunk-recorder: Records calls from a Trunked Radio System (P25 & SmartNet), which can monitor and record all calls, and yeah, it puts out so many messages even in normal times. And even without PPB dispatch and one of the voice frequencies, I think I got GBs of audio per day.

I'm using this open source project https://github.com/robotastic/trunk-recorder to do the recording, but here is a screenshot of GQRX to give you an idea of how software radio works- instead of hardware designed to listen to one channel, it samples a big chunk of the spectrum and then uses software to "tune" the individual channels- so it can listen to everything at once, no need to channel-hop, etc.
