I have noticed the sound quality on the P2 at times. It appears that it is related to the system users. Some systems, I hear phase 2 traffic crystal clear, others, it sounds muffled, just as Homeboy says. I think that is an equipment related issue on the system user end. As far as the DMR holding, I have shortened that by changing the hold time. If you set it to zero, it doesn't hold near as long. I agree on the conventional DMR. Not much info there, but if it works.... As far as as the "tone" settings (CTCSS, DCS, CC, etc) I use Proscan for programing. You can set up your audio type to "ALL" so it will decode whatever format it is receiving, along with the search mode in the "tone" column to let you know what that specific figure is. I don't listen to any CAP + systems, so I cannot comment on that. Utilizing the entire display may be able to be done with a firmware update. More knowledgeable people will have to comment there.
