The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Hannington (Hampshire, England) mast?

Adrian,

Yes I have done what you suggest. I carried that out earlier this week. That was quite nice as it has rearranged the channels into the correct order which before didnt happen.

Dave
You may well be correct. Would this show up on the power check feature on the recorder? I have gone through each of the channels that should be broadcasting other multiplexes. These are all reading absolute 0 (bar one which flickered for a fraction of a second on 18% before giving 0). If it were the case that the signal was now too high, should these readings (which are only to do with signal strength not what is on the signal) come out as zero?

tim: If the receiver is overloaded with signal, then the signal strength readings will be likely to be misleading.

That is because the circuitry is overwhelmed by the signal, it can't function normally.

The fact that there is an initial blip of 18% and then nothing could give rise to the theory that the signal level is too high.

Try putting less signal into the TV. For example, remove the aerial lead and hold the plug close (a centimetre or so away). The aim is to loose a bit of signal. Bear in mind that the receiver may take 10 or more seconds to adjust to your change, so wait.

Or as I said above, try removing the outer part of the plug (if it's a screw-together one).

When you do this, observe the signal strength meter and see if it increases.

Just a thought. With the system I have, the lead from the aerial into my freeview recorder. I then have a lead going from the out socket to my TV. It was my understanding that this means that my tv would get significantly weaker signal?

If this is the case it cant be that the signal is too strong, as on my tv I dont get any channels at all (including channels from PBS1).

Would this rule out the signal being to strong?

tim: Where a signal is split using an unpowered splitter (i.e. no amplification), then it stands to reason that the strength of the two outputs must be less than that of the one input.

However, where an aerial lead "loops through" a device, the signal is amplified to counteract the loss caused by splitting it.

Presumably your Freeview recorder also has reception problems in the same way as your TV?

yep, identical. Due to the fact that it finally allows us to record things when we are not here again, we have the cable going into the recorder rather than the tv (it then goes from the recorder to the tv as we have had it before but it seems signal is not strong enough for that)

I have no idea whether the tv would have recieved coms5 for the few days that it was available, as I did not try it during that period.

ITV-1 (Ch.3) still glitching off, no signal for 2-3 seconds then Ok again from Farnborough GU14.

Is the airport messing about with some new equipment that upsets just this one channel?
(Should have built housing on that damn site!).

Tim,

Have you checked with your neighbours to see if they are having the same problems?

Hi,
Got a new screen message today advising I will lose channels on May 5th and to retune (again!!!). I've seen firmware over the airwaves updates listed for around this time, but these don't relate to my TV model. Any ideas on what will be lost or changing?

Stuart Tier: Just checked on Hannington as well as other stations that you could be receiving from and do not see any event taking place on the date you have mentioned.

I would be inclined to treat the message as an error.
