there are issues with the ttsl report - what adn why it's indicating 0 tune-ins for a large number of stations i don't know and i won't be able to answer until i'm not on holiday (yet am still having to keep an eye on things here).
as for why the station is not appearing, all i can say is to check the DNAS's logs and look for anything explicitly relating to messages starting with [YP2]
as there is nothing in any of my reports relating to the DNAS you've provided a link for despite it indicating that it's got a 'YP connection'.
so i have to assume some error has happened and the DNAS is not able to communicate with the YP but what, i do not know and cannot attempt to check the YP logs at the current time and so you looking and posting back any errors from the DNAS log will make it easier to determine the cause of the issue.
