Had to recheck frequencies to set up a PCTV Dongle (the software I was using had an out of date list).

Surprised to find that the "LW" signal was on - a whole frequency, with nothing on it until Feb 2014, and then only one channel - would make more sense if they were going to fill in with the "only available in Manchester" channels, as assigning a whole mux with just one channel is flaming stupid.
It reported good signal, 0 channels, so not even a test channel!
