Nigel : Yes, high pressure certainly does have an affect on reception, and in most cases one of a dastardly nature, although occasionally (very) it can be positive by enabling a signal to be received from a transmitter normally just out of range.

I had a quick look at the pressure maps before making this reply, and judging by that seen it would appear that the UK is in for a rough time of it for the whole of next week as far as reception problems are concerned, as a series of waves of high pressure are seen to sweep across most of the UK excluding the Northern areas of Scotland, with the South Western area's being severely affected at times.

Needless to say, high pressure is the most likely reason for the problem mentioned.

Nigel : Hi, Nigel I totally agree with jb38, regarding Solent TV. It is not listed as being receivable at your location. On the other hand, BBC Radio Solent should be receivable at yours, because that is transmitted on a high power multiplex. The Freeview channel number for BBC Radio Solent is 722 for you, should you wish to hear local news through your television set. Richard, Norwich.

Every night at precisely 1am I lose the TV and get a No Signal message. Does the transmitter go to reduced power or what?

Margaret Baker: Freeview transmitters do not reduce their broadcast power overnight. If it is happening at the same time each night then you are likely suffering from electrical interference caused by something operating on a timer switch.

Hello,

Apologies if this is covered elsewhere and I'd be grateful for a signpost if it iis. I am very confused about BBC News 24 HD reception in my area. I moved here last November and received the HD channel sporadically (signal strength was variable). Then it just vanished completely for no reason.

I'm receiving BBC1, 2 and 4, ITV, Channel 4, 5, QVC, CBBC all in HD without any problems. Postcode is SO18 and set to Rowridge transmitter. Any ideas on how to get BBC News 24 in HD?

Thanks!

JM: Apart from the possibility of an iffy aerial connection, double check any jumper leads used, the other thing that springs to mind is whether your aerial is mounted vertically (elements up/downwards) or horizontally? as some viewers have aerials mounted vertically to take advantage of the TX power being higher on COM4/5/6 on vertical over that on horizontal, whereas BBC News HD is only transmitted on horizontal polarity at a much lower power that even the three COM's mentioned on horizontal, BBC News HD on COM7 at 24Kw, the other three COM's being on 50Kw.

Apart from having a look up the aerial to check the polarity, try manually tuning in COM7 on C31/554.0Mhz, but do not press search after having entered 31, because if anything is being received the level the signal is being received at will appear in the signal strength bars.

Further advice as required.

Our freeview box has ceased to work as before Is there a problem with the freeview box ? Do we need to use the Sky TV Guide button on the remote control. Could you please advise . My Postcode is PO17 5HA.

Juliette: Check the box by plugging it into another tv - if its not working, then its the box, but check first if its your aerial system at fault.

However, if itsa sky box (you mentioned the remote), then thats skys problem.

This site is now showing vertical polarity of COM4/5/6 as being derated to 50Kw rather than 200Kw. This was the reason for vertical polarisation of the aerial. Has this really been derated as if so, it would make sense to change back to horizontal to get the additional 2 MUX?
