PJS:

With the Planned Engineering, any one or several multiplexes could be affected at any time depending on the nature of the work being done. There could be service interruptions or reduced power (the latter possibly causing picture or sound break-up).
You should NEVER retune when this sort of work is going on as it can usually end up just clearing the correct tuning, or even getting tuned to some more remote transmitter whose signals will not be stable.
If you do so, you'll end up have to retune again when the signals are back to normal, and as you can't be certain when that might be, you may have to try several times. If necessary, manual tuning on the affected multiplex(es) would be better than a full auto-retune as you don't run the risk of messing up those multiplexes that are ok.

Used to get all Freeview channels from Rowridge where the aerial is pointed. For last 18 months or so, signal is from Findon. from which we get only Freeview Light. This is true of a corridor about two miles wide acress Bilsham, Middleton, Felpham, Bognor. Half a mile south of me get Rowridge, a mile north they get Rowridge. Why do I NOW only get the Freeview Light from Findon. This certainly affects several thousand people in the area all of whom seem to have aerials pointed at Rowridge from whence they used to recieve the signal.
Can you explain what happened to necessitate the change?

Stuart: I suspect it's probably down to interference. Although it's too far away to receive, Crystal Palace uses the same frequencies for the COM4/5/6 multiplexes as Rowridge and you're unfortunately in the area where the signal from from both transmitters cancel each other out.

Stuart:

Whilst what StevensOnln1 has said is correct, Findon and Rowridge are in opposite directions from you, so you must be getting the Findon signals off the back of your aerial - assuming it's still intact and correctly pointing at Rowridge. Findon is also somewhat closer! However manual tuning might be a solution.

Rowridge is at bearing 255 degrees (almost WSW) and Findon is at bearing 66 degrees (almost ENE), Crystal Palace is almost NNE Rowridge transmits signals with both Horizontal and Vertical polarisation, whereas Findon is vertical (Crystal Palace is horizontal). You aren't predicted to get good COM4/5/6 reception from Rowridge with horizontal polarisation (poor to none), it's better vertical.

Are the rods (or squashed Xs) of your aerial vertical, is the reflector of the aerial still intact as well as the other elements and still pointing WSW? The aerial needs to be intact and correctly pointing to reduce interference from other transmitters, but sometimes that is difficult.
Also what will not help matters is that there is currently some tropospheric ducting with the high pressure weather affecting mostly the South/SW of the country by varying degrees and signals can change by the second or remain stable for much longer periods. This can affect different frequencies by differing amounts at different locations, just because one multiplex might be affected doesn't mean another will be.

So you could try the following, first you'll need to clear the current tuning, usually best done by unplugging the aerial and doing a full automatic tune, nothing should be found clearing the old tuning. Plug the aerial back in and find the manual tuning section in the settings.
In the multiplex order PSBs1-3, COMs4-6, manual tune the following UHF channels for Rowridge -
C24, C27, C21, C25, C22, C28. You may have to try several times if there is any interference around.

IF you happen to find that despite the way your aerial points, you get better stable PSB reception from Findon then there shouldn't be any issue with the PSBs tuned to C44, C41, C47 and the COMs from Rowridge, but I don't know if you'd get a different local news variation from Findon.
IF your aerial turns out to have the rods horizontal, the channels are the same but you could try adding C55 for COM7.
Again, you may have to try several times if there is interference around.

Mr MP Lofthouse:

Depending on where you are in Blandford, there are 3 transmitters that you could normally receive and reception will be different from each. If you believe you get your signals from Rowridge, check in your TV Tuning section that you are correctly tuned to the Rowridge UHF channels that I listed in the post just before yours.

Which way is your aerial pointing? Are the Rods (or squashed Xs) horizontal or vertical? It should be pointing somewhere around bearing 110 degrees (~ESE) for Rowridge. Do you get Meridian or West Local news?

A full postcode will enable us to check predicted reception. I can't find any faults listed by the BBC or Freeview for any of the transmitters that you should be normally able to receive, nor are any of them listed for Planned Engineering.

Last few days several of the channels on com 6 are pixilated or just not there, I watch DMax quite a lot so missing it somewhat, up till now has been fine is there a known problem, a reduction in power or just the jot weather?

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
