[op25-dev] Re: H-CPM demodulator for SDR?

Yes, please ref.  https://gitea.osmocom.org/op25/op25/src/branch/master/op25/gr-op25_repeater… The code is currently released as experimental-only, YMMV.  It should, however , properly decode an H-CPM signal (under the proper conditions).  See the commentary for further details.

This is the modulation used by the SU when transmitting in an APCO P25 Phase II system. Thanks Osmocom for all the pioneering SDR work you have done!
