If I'm not mistaken, all SDR's will do trunking. You need two SDR
(hardwares) to do trunking. One of them will basically scan the
control channels, one will scan the voice channels, and then you run
two copies of the SDR software. And then obviously two antennas...
I've never done it myself....

Does anyone have an SDR that will do trunking?

The agency in question had one person screaming for a while on the Internet. Now none. But, thanks for the suggestion.

SDRAngel will decode P25 natively. It does not trunk though.

Sadly, the 246 cannot monitor P25. You need a digital scanner.
It is possible for monitor P25 for cheap using your computer.
Buy one of these RTL-SDR radio receivers for $25 that is USB: https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/
Download the free SDRSharp sofware: https://www.rtl-sdr.com/tag/sdrsharp/
Add this crude scanner plug-in to that software: http://www.freqmgrsuite.com/
Pipe the audio through the free DSD+ decoding software: https://www.dsdplus.com/
This kludge is finicky and slow, but it's not $600 like a Uniden SDS-100. :-) It works for my semi-rural area where there are only three P25 public service frequencies and one DMR ham repeater to monitor. My 246 handles the rest like champ.
