Just an update - I went direct to the website and tried playing it through there and it is working fine. What's going on with the Tune In radio app? I tried all your stations on there and it was all BBC2. I'm relieved that your station hasn't been taken over. I wonder how many other people have had the same problem.
Thanks for replying :) I'm listening from Canberra, Australia through Chrome on my ipad, but I had tried to listen to it through the Tune In app on my ipad. Every Lynx station I tried through Tune In was BBC2 - but interestingly in the little info box at the bottom it showed the correct information (ie; the Lynx info). Very odd.
