Is the SDR very hot? There was another recent case where the SDR would overheat and shutdown.
Based on the information provided so far, I see no reason to believe that this is a bug in the direwolf application so this should not be in the "issues" section. It would be more appropriate for the discussion group. https://groups.yahoo.com/neo/groups/direwolf_packet/info;
