[App_rpt-users] DIAL Question

Thu Oct 29 11:33:39 UTC 2015

Mike,

You are correct in the statement that the DV4mini needs additional hardware to handle the transcoding from a digital radio. Once I get my nodes back up on my Raspberry Pi, I will work on an updated version of the D-STAR channel driver that supports DMR and Fusion AMBE encoding and decoding as well as radio control functionality for the DV4mini.
