      James M3IYL has been in contact to express concern that his station was thought in error to be causing an issue, and was rightly upset that nobody contacted himself about the error.

      Apparently the issue was another stations faulty TNC. And has been resolved.

Don't know if it's all the time, because I don't normally zoom things out far enough to see Liverpool, let along the other side of the Atlantic, but it appears that he or she is still generating the corrupt packets as I type this. I see the corrupt position in aprsisce - haven't had a chance to check in anythign else except aprs.fi at the moment.
