Hi, seem to be suffering a similar problem to that descibed by Terry J Russell. I'm at SG12 0XY and my signal (CH30, 545.841 MHz) keeps dropping, causing to be displayed on my TV. This happens on a Sony 32EX403, I can watch the signal bar drop from 100% to 0, bounce around 30 and then back to 100% when the comes back. The strength sits at 100% all the time. I have no issues with SD .

I also have Freeview HD PVR, which does not seem to be as sensitive, but I do get some breakup. Not sure if this is , or the TC itself.

Luke Bellamy.Ware,SG12 0XY.
Your second and last paragraph at least could be down to atmospherics/ due to the recent brief settled spell due to end very soon.
As for your first paragraph if you do receive transmissions directly from itself is your horizontally polarised and if so is it a group A type Yagi or group A type X-Beam aerial as such (red coloured tips).One possibility could be that BBCB (HD) generally are more prone to pixellations,break ups and than the present five remaining SD multiplexes.

This evening (29 June) after about 22.30 the strength on Ch 25 (10 ITV 3, 27 ITV 2 +1, 30 5*, 31 5USA, 38 Quest, 39 The Zone, 44 Channel 5 +1, 72 CITV, 16 QVC, 23 Bid TV, 60) declined and the became unuseable. report "no problems". Is this from an outside source on just one channel or something else?

What is the best sort of indoor to use to get in Leatherhead? We have just moved inmto a new flat in the town and only have a Virgin connection. Would prefer not to have to subscribe to Virgin unless absolutely necessary but unable to put up an external aerial.

Richard: The for reliable of from at your location is not brilliant - officially it is classed as poor. This is due to the risk of from which shares the same . A check on the William Hepburn's Tropospheric ducting forecast shows slight ducting between London and the South coast for late evening so this could be the explanation for your wobbly signal on SDN. The other possible explanation would be interference from a faulty street lamp which would have switched on about the time in question. It might be of interest, if you continue to have problems with reception from Crystal Palace, that is predicted to give good reception of the COM muxes at your location.

John Quattromini.Unfortunately nowadays indoor set-top aerials have become much inferior than what they used to be it's difficult for me to specify which is the best.But if you look up the ATV Aerials and Television of website they do retail superior indoor set-top aerials and they do provide a mail order service too.
