Thank you David & Chris.

Yes, I know (from this group and others) that the COM muxes are on restricted power and perhaps it would have been better for the appropriate bodies to inform people of this especially as there is no end of aerial installer vans appearing in our area with many disgruntled consumers wondering why a complete change of equipment, retuning etc makes no difference.

It is sad that a change to different channels / bands has resulted in a complete loss of the ITV, 4, 5 channels whereas in the early stages of the switchover they were all present and clear.

Freesat may well be an option but I feel sorry for the multiple households (including mine) that would now have to pay for the installation of dishes in addition to their shiny new supposed digital high gain aerials.

A sad state of affairs and one that should have been be managed better (as an aside I design RF transmission equipment and so have an insight into what may be occurring at Oxford and elsewhere).

I look forward to receiving a rebate on the license fee so we can all go out and purchase dishes.

Briantist: Yes, could I also say thanks for updating Oxfords TX power info, as just like Chris.SE I was also aware that you did have this fact mentioned in your "after switchover" notes, but I think that most people checking on power levels possibly didn't notice these qualifications thereby causing confusion.

@Steve- I work for a TV aerial company and since switchover we have found that there is a particular problem with Philips TV's (the ones that have a yellow bar when scanning). My boss has spoken to Philips technical dept. and they have admitted there is a problem. They were writing some new software asap to get over this problem. We had a customer call us back yesterday to say that he did a software upgrade then a re-tune and now it is working and storing the channels as before DSO. This might work for you?

Yet another update: my aerial is almost certainly a Vision 48 element as shown at Vision 48 Element High Gain TV Aerial

When installed (replacing an old C/D I think) this greatly improved reception of the outlying multiplexes on C29, C34 and C68. I can see it would be somewhat over the top for current conditions.

I understand fully your first paragraph which appears to have been written from knowledge not hindsight. Why was the Mendip / Beckley clash never highlighted over the need for new equipment: prior to the temporary mast scenario, I was getting a decent digital picture on an analogue TV via a digital DVD recorder, but when MUX2 disappeared the only advice in these forums (yes I know it is community opinion only) was to get rid of the analogue TV and VCR though to be causing single frequency interference. Why oh why could someone just not say ITV will be bad for 2 years?

Jonathan: Just reading your postings, and I would particularly look forward to reading an update from your tests, especially if you can pick up ArqA / Mux Ch59, and at what level as this seems to be a problem channel by being on lower power(12.5Kw) sited right next to one on 100Kw.(D3&4)

Also, and as you obviously realise, your aerial system is pulling in far too strong a signal, as you are only 5 miles away from the transmitter.

Briantist: No problem, thanks for the update, I'm just surprised you manage to keep up with everything.

Jonathan; Thanks for the update, as jb38 I look forward to the results of the testing.

Richard: I'm not sure what Mendip clash you're talking about, Mux 2 at Oxford was adjacent to Mendip Mux D before switchover, and the two stations ran like that for ten years since March 2001. Both got subsequent power increases, Oxford in August 2002 and Mendip some time in mid-2003. From January this year, Mendip C67 had a power increase from 10 kW to 26 kW so ArqB could launch in final mode, restoring Sky Sports. This would presumably be the upper limit that could be used.

People out in Swindon might have had a problem on occasion with adjacent channel interference (caused by filtering being imperfect - in the real world, some leakage into adjacent channels is inevitable - and a little cost-saving on using less complex filters where there isn't an adjacent channel at the same site). Someone in or near Beckley itself would be unlikely to have this problem except in incredibly rare weather conditions.

I'm really not sure what your issue was - some local source of interference does seem the most likely. If you're having increased problems now - the same on all multiplexes - I'd look into sources of impulse interference like a thermostat or other motor.

We live in a block of flats in central oxford and since the completion of the digital switchover on 28th September, we have lost COM5 and COM6 (as listed in the above channel list), or sometimes referred to C and D. These are the MUXs carrying the likes of Dave, PickTV, Film4 etc.
We received these MUXs before the switchover occurred, the signal was sometimes weak, but now there is nothing there at all, I've even tried a manual tune and it reports there is no signal. I've tried repeated factory resets and checked for interference from other equipment and that all the cables are ok, although I'm pretty sure this isn't the case as the channels just disappeared on the 28th. As we live in a flat with a central aerial source I can't check the aerial at the moment.

I've searched this site but couldn't find a reason why these would drop out in such a way, but if there is please point me to it as I'd love to get these channels back.
Thanks very much.
