> including using SDRs to vacuum up wide swaths of RF and then store call data

Been there, done that. The technique is scary-good, even with cheap hardware.

Capture everything, sort by talkgroups, form listen queues ("police", "fire", "police NOT university",) prioritize, and place recordings in queues. Stream queues through ice cast. Drop low-pri messages if you fall too far behind real-time.

Speaking of: if anyone wants nearly two years of uninterrupted Seattle police radio archives (and everything else from KCERS), they should get in touch.

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

Will unitrunker handle multiple simultaneous captures at once?

One of the magical things about the SDR approach is being able to synthesize dozens of streams from a single antenna and several SDR devices. The setup I had could capture ~10 simultaneous transmissions before things started to fall apart.

I think there's a roundabout way to go about doing that. Essnetially create a lot of additional voice VFO's and then set each one of those VFos to have only 1 talk group with its priority set to 1. And then set the output of each VFO to a different VB audio cable in, then source would be VB audio cable out in audacity.

The hack RF definitely supports grabbing an entire 20Mhz swath of bandwidth that covers all the signal and voice frequencies.

Id be super curious to hear more about your setup, both hardware and software.

Yup, see our Broadcastify Calls Implementation

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.
