re my earlier post about mux c issues:
it has improved since then, but today reception of mux c is just as bad, signal is around 70% but quality is zero!
All other freeview channels are fine, how can it be that just mux c is playing up?
I can only guess some kind of interference or transmitter work in progress..

mux c issue solved!
its the computer sitting next to aerial booster amp causing interference. As soon as its switched off, signal quality on sky news (mux c) shoots up to 100%.
Need to put mains filter to the pc or move it away, or replace aerial coax with double shielded one or both..

Skynews on Freeview disappeared yesterday evening (Blue screen with message: problems with receiving signal, check aerial connections). Remains missing but adjacent channels (both sound and vision present). Aerial connections appear to be fine. Retuned TV has revealed a number of other channels are missing (Fiver, CNN ...). Crystal Palace transmitter does not show any problems. What has happened?

Furher inspection has revealed that, following retuning, channels on Mux A, C and D have gone AWOL.

I have lost ITV 1 and various other channels within the last week. All BBC channels are fine. A message was shown on my television some time in early December but was only there for a short time and I thought I would deal with it the following day but it vanished. I live in East Molesey and had no previous problems, in fact reception on all channels, including Freeview was excellent. Can you help me please?

It must be magic (or a delayed Santa)!
At midnight last night the channels were still missing. At 8 a.m. this morning I was prepared to undo and remake the aeriial connections but on checking (I had not retuned the digi box so it still had the previous tuning regime whereas the tuner in the television had now lost them) but there they all were. What a brilliant start to the day but I am none the wiser as to what to do should there be a recurrence (Did I hear "Sit on your hands and be patient")?

jol: Just use the PVR to watch Freeview, don't attach the aerial to both it and the TV set.
