Galaxy 13 is a weird satellite, I have more trouble with the services on it (as far as being perfect one day and completely gone another) but as I write this I am receiving NASA, but Tvheadend reports signal quality of 80% but SNR jumps all over the place, though for the most part it stays at 40% which is really low (not that I consider TVheadend's display of these figures as entirely accurate). However the picture seems solid, and that's with a 7½' dish. Whether it will still be there tomorrow is anyone's guess.
