What exactly is happening on 18th April 2012? All I can find is "technical changes". Does it really just mean that channels 30, 33 and 37 will change frequencies and signal strength increase to the same as that currently for 24 and 27, instead of the abysmally low level they are at the moment?
My Panasonic set and recorder both retuned perfectly first time, but my Samsung will not pick up 30, 33 and 37 in spite of several retunes and factory condition reset. From what I've read on here, I'm not the only person having problems with a Samsung set. If the strength of these three channels is to be increased, hopefully that will sort the problem out.

Jean: The frequencies of the COM muxes at Rowridge will change on 18th April 2012 as you said. The power increase for horizontal polarised signals will only increase to 50kw however, so these might not be as robust as the PSB muxes, due in part to the COM muxes sharing frequencies with Stockland Hill and Crystal Palace. In order to address this problem the broadcasters will additionally transmit all muxes from Rowridge with vertical polarisation at 200kW. In order to take advantage of the stronger signals viewers will need to turn their aerials so that the rods are vertical. Wait until 18th April, then see what reception is like to see if this is a necessary alteration!

I cannot get a signal on AV1---AV2 is fine and I have tried retuning.Any help?

KMJ, Thanks for that. Why hasn't that been explained elsewhere? Some of us aren't technically minded, but can easily retune a TV set - so simple an explanation.
I'd go for Freesat, except I want 'Dave' and 'Yesterday' and they're on two of the missing channels!!
Thanks again - we'll see what happens on the 18th.

BH9 area. Since changeover I have lost some channels on my Panasonic TX-28DTX1 (including all BBC channels). Retuning repeatedly has made no difference. To eliminate aerial/connection problems being the issue I moved the TV and used the same aerial connection as my other TV which has successfully been retuned and receives all the freeview channels. Logically the signals for all channels are available but still the same channels still cannot be picked up on my Panasonic! I have tried tuning the TV with no aerial and then re-tuning still no luck. We lost BBC channels only on 7 March but hoped things would improve after 21 March. Alas things have got worse. Vital normality is restored as sanctuary for Match of the Day etc is required! Any ideas? TV has analogue/digital switch on remote. Would Freeview box help?

I was looking forward to a nice strong signal only to find out C30, C33, C37 are staying on low power so I now have two extremes 21, 24, 27 are to strong and C30, C33 are fluctuating/unstable if I attenuate the strong I loose the low power commercials
Hopefully when they go up to 50kw it will solve my problems if it doesn't I guess I'll have to use the vertically polarized
One question can you use a wideband aerial in the vertical polarized position ?

Richard Smallcalder: WARNING - Panasonic CRT IDTV problem with latest channel launches - Freeview - Digital Spy Forums has some information about this set. My suspicion is that it may not support 8K mode, or not without a firmware update. Contact Panasonic to see whether it is compatible, and whether a firmware update is available.

metcalfe: AV1 and AV2 will be devices connected to the TV's AV1 and AV2 sockets. Check that whatever is plugged into AV1 is turned on.
If AV1 is an analogue video recorder then no, it won't receive anything over the air. You can still play back previously-recorded programmes. Some VCRs are able to record whatever programme you're watching, from the SCART connection. To record a different programme or do scheduled recordings, you could make the VCR record from a separate set-top box, again recording from the SCART connection, but this is quite difficult to set up. It's far easier to replace the VCR with a hard-disk-based Personal Video Recorder.
If there is nothing plugged into AV1, you shouldn't expect to see anything.
If there is something else plugged into AV1 and it's not displaying even when it's on and operating, try disconnecting the SCART cable and plugging it back in.

Quite a few have asked about changing from horizontal to vertical polarisation. I am lucky in that I have a loft aerial. It is a wideband, although this is not recommended, however, it works and if it it ain't broke it doesn't need fixing! I get enough signal now anyway.
I rotated my wideband aerial through 90 degrees so that the elements are now vertically aligned but obviously the whole thing still points towards Rowridge. All it took was to release the clamp holding the bar (which points to Rowridge)on which all the elements and reflectors (at the back) are mounted. As it is easily accessible in my loft, it took a few moments with an adjustable spanner to release the clamp, pull out the bar, twist through 90 degrees and push back in the clamp and retighten the two bolts on the clamp. All the elements are now vertical. As I said in a previous posting my personal signal strength went from 61% to about 91%, with 100% quality. I will be watching to see if the co-channel interference will be less than it used to be from the French transmitters. There seem to be some high pressure areas floating around. It may not be too long before we can all see the improvements or not?
From my background any aerial can be rotated simply in this way. I changed from roof mounted aerials to loft many years ago, having had rusting and bird damaged aerials too many times before, despite having a slightly lower signal. It is worth it because you avoid having to use a ladder or any aerial company's engineers!
Engineers should not charge much at all for rotating the aerial from horizontal to vertical polarisation if roof or chimney mounted. It should be very easy indeed. If in the loft, do it yourself?

Derek Green.If you reside in a strong/medium reception area within Rowridge itself then a group W wideband aerial on an all group A frequencied transmitter such as Rowridge is ok.It is only in a weak/poor/marginal signal area within an all group A transmitter again Rowridge being an example,plus the likes of Crystal Palace,Durris,Caradon Hill,etc,that a group W wideband aerial are not really recommended due to their inferior response on the lowest frequencies such as low signal gain and occasional pixellations and worse still sometimes unable to receive multiplexes as such,common with cheap inferior contract aerials.If as you state it works for you,dont change it !
