That's the nature of narrowband AND digital audio combined. The digital audio is akin to audio noise reduction (like Dolby NR) in that the path noise is virtually eliminated making it much easier to hear the transmitted audio. Of course if the signal strength suffers so much that the receiving end can not correct for the errors then the signal garbles or "goes digital". Here at home we often use D-Star simplex over many miles and have enjoyed some good results so far. My group at Dayton stayed in the same area and used digital audio all weekend with no interference and improved comms between units inside the arena to units outside the arena as well as from the motel to the arena. We've never been able to do that 100% with an analog channel. Gary
