Kind of shitty that sdr-trunk is the only viable software for decoding P25 using an SDR. SDRAngel has a closed issue saying they were going to add a decoder for it, but I think because of patent encumbrances they've dropped it.
I learned that most SDR hardware is supported by a vendor-agnostic project that provides an API called SoapySDR.
Might get into it a bit after I'm done my current project with my BladeRF.
