P25 to C4FM

I'd really like to use my P25 radio to talk to C4FM. I can do this but only if the C4FM user is transmitting in VW mode, which very few do. Is there a way for my P25 radio to receive audio from DN (half rate) C4FM?

No, as AMBE hardware does not support IMBE encoding/decoding, which is used by P25 and C4FM/VW mode.

C4FM/DN mode uses the more recent AMBE codec, as well as DMR and NXDN.
