Hi!
Returned home today from 2 weeks holiday abroad (I did think of you all retuning on 28 Sept) and retuned my own TVs about an hour ago. (I live in Faringdon, by the way and receive transmission from the Oxfor4d mast). PSB1, PSB2 and PSB3 with all aassociated channels are great, but SDN, ArqA and ArqB are pretty grim, and I njow have either no reception or flashing on and off on programmes for these wavelengths (can't watch my favourite QVC or the Jewellery Channel!!!). Do I understand that these will be sorted when further retuning is necessary next April? I can see from the diagrams on the web page that the frequencies are all very low on these. At least I have good ITV1 reception now - got very tired of watching Corrie on the internet all the time!! Sorry I am so completely untechnical (I am sure there are plenty of other ladies who aren't!!!), but I am just wondering if it is worth leaving it alone with what I have and waiting until April.
Thanks in anticipation of a non-technical answer....

tigi - have you looked back - others have probably already solved the same problems - maybe too STRONG a signal, ar a box that no longer works

Paul - Yes they did. The only problem I had before was with Mux 2.

Robert: Sorry not to respond sooner, I don't have any suggestions as to why you should have problems with 1 or 2 channels on a particular mux but not other channels on the same mux, other than make sure that you've done a full reset/new install on the box.
This "static". Do you only get the spark after the flylead has been connected for a while or can you get it every time you disconnect the lead even if it's within a second or so of reconnection?
If you disconnect the box from the TV, do you still get the spark?
Can you get a spark if you touch the flylead to mains earth (the earth on a mains socket - wire a plug with a wire to the earth pin only for the test)?
Regarding the booster, yes you're very liklely to need to carry on using one - signal is not very strong (especially the COM muxes - I'll be posting further on that.).

Tigminor: I'm surprised you are having a problem with the SDN mux (QVC, The Jewellery Channel, 5*, etc) as you had it OK before DSO and the power has doubled although still low until April next year when the situation should be better with power increases on the COM muxes.
Digital UK's reception predictor for your location isn't good for the Arq A & Arq B muxes at this time, I can only guess that there is possibly a lot of multipath or local screening in your location (did you get much ghosting on the old analogue pictures at all?), especially as further towards Swindon on a virtually identical bearing reception is better.
I doubt that you are getting too strong a signal at your location, but if you are using a booster, try turning it down (if variable) or bypass it just in case the situation is improved. Other than that reception of the COM muxes willl continue to fluctuate until the power increase.
It is worth checking that your TV's are tuned to Oxford & not any other transmitters since power has increased. Do a full reset/new install by following the link "Freeview reset procedure" in the yellow box below, BUT instead of doing an automatic tune, do a manual one using UHF channels C53,C55,C59,C60,C62 & C57 for the HD mux.

Chris - many thanks for your help. Actually, the problem has now righted itself on my main tv and I am receiving all channels steady and clear. The three channels I mentioned previously are still not working on the set in my bedroom, though I have the same make and model of settop box and it is obviously working through the same aerial so makes not much sense to me. However, I hardly ever use that set so am not bothered. The main thing is all is now ok on my main set. Thank you for taking the time to help and I will note your comments.

Since the oxford retune mux c programs are impossible to watch due to breakup. We are in WIndsor off the crystal palace transmitter. When will the power be turned back up?

Phil: Can you provide a full postcode please?
If anything, Oxford's switchover should have *improved* your reception of Crystal Palace Mux C, because Oxford no longer uses C34. This channel is one of those being cleared for the "digital dividend" so no transmitters have started up digital services on this channel after switchover.
I can't say I'm having any issues with Mux C in Reading, or at least no more issues than before.
