I am on Sandy Heath and I did a manual retune. MUX C shows as C67 but channels are showing no service available. I also tried C52 but no difference. Is there a problem with MUX C.

John: Different receivers work in different ways. It sounds as though with yours that you're going to have to do a full auto-tune.
I think that some receivers don't see the new location of particular muxes because as far as they are concerned, they already have them stored (albeit on the old channel numbers).
If running auto-tune doesn't sort out your issues, then try this procedure here:

Since the re-tune of Sandy Heath, I cannot receive Sky News or any other channels transmitted on C67 (9842.O MHz). I have line of sight visibility of the mast at Sandy Heath. My post code is PE19 5DA.

I tried retuning on Ch52, and luckily I live in Biggleswade, so all the channels tuned prefectly well, nothing on Ch48.

I have two TVs and a computer (iMac) with a TV tuner card (external, Eye TV). I have always been able to receive all multiplexes on the two TVs, living room TV fed by roof-top aerial and bedroom TV fed by set-top aerial. However, until yesterday's retune I could only receive the two PSB DVB-T multiplexes on the computer. Now I can receive one more multiplex, the one that has Russia Today on it, and just using the set-top aerial, it breaks up and is barely watchable. However, I put the aerial on an antique silver salver and immediately noticed an improvement in reception. Improving the contact between the metal base of the aerial and the salver with a piece of aluminium foil improves reception of this multiplex to the same quality as that of the two PSB multiplexes.
Question 1. Why?
Question 2. Will using the salver as an aerial in contact with aluminium with steel on the other side cause any damage to it? It's an antique and probably worth a bit, if only for the silver value! (52.3992,-0.7201)
