Having read through that page I think I now understand why I pick up mux 1 on ch 45. This is transmitted by Dover but should not according to the coverage map get anywhere near my location. The problem is that probably because of my location on the N side of Broadstairs at about 130 feet elevation I am high enough that ch 45 gives a better signal than ch 68 most of the time, and my IDTVs all select the strongest signal and will not allow me to save duplicate channels.
The problem is one of coverage, according to all the places I have checked this small part of Broadstairs should not get any Freeview until switchover next year, this is in my view grossly unfair, after all it is not an area of low population numbers. I feel that they should boost the power now in order to provide an adequate Freeview service to this area and not wait for switchover - its not good enough to rely on the chance reception.
All this said t still does not answer my original question about why the signal disappears completely and suddenly. As I said I can understand why the signal might degenerate but this is not what happens, it simply goes to nothing just as if someone switches it off.

My point is that the channel disappears completely, I fully understand how the digital signal is transmitted, my point is that the IDTV sees no signal at all on ch 45. In order to find a digital signal it first has to find a signal on ch45 and then tests the signal quality and gives bar graph readings for both. When this happens it cannot find anything on ch45 to test!
I know our local MP is getting involved to try and address the freeview issue locally which is unacceptable. We are completely without support because the powers that control this have decreed we do not have a service so anyone living in the central Broadstairs area cannot get anywhere complaining. This whole thing is just a mess and is being handled very badly.

Stuart: The low-power digital transmissions had to be squeezed in, however it could be done, but in a way that minimized interference to anyone else's analogue TV transmissions. Digital was considered an add-on service initially. The south coast was particularly difficult due to international co-ordination. It meant restricted radiation patterns, odd frequency selections, and limited power levels. Some transmitters had to have more than one set of aerials pointing in different directions, using different frequencies, and Dover is one of those.
The switch-over is more a switch-off - a switch off of the old analogue signals so that high-power digital signals can replace them. Even then, they are not designed to cover the whole country or even the whole population - the estimate for acceptable analogue reception was 98.5%. The public service broadcasters have to match that level for digital service, the commercial multiplex operators don't.
The predictor currently shows no prediction for Mux 1, 2 and A. After switchover it shows a relatively low probability of getting reliable results, indicating variable reception.
I'd look into Freesat.

Stuart D45 is interfered with by high power French digital from Dunkirk. Any hot or settled weather and you are in trouble. Nothing can be done till power up next year , sorry !

OK, OK I know all about the inversion effect etc. but the reception in Broadstairs/Pam Bay Area has now got silly on freeview (or in my case NOview) just done a rescan and found 36 Channels as far as I can tell all DUTCH! I know our local MP is meant to be helping but it has now got silly, completely beyond belief, what do we pay our TV licence for, can we get a refund for the days we have no coverage! Can we push for the "Go Live" date to be brought forward, I think not but if the powers that be DO look at this Blog/Site can they think of, as a temporary measure at least, putting a digital relay on the Margate mast and letting us have at least the main Channels (BBC, ITV, CH4 (and 4 offshoots) and Five with 5* and 5USA as there are more OFF days that working days now!

Nick I have no answer for you save to suggest you bend the ear of our local MPs to see if we can get something done to improve it. It is unacceptable to say as Malcolm has done that even after switchover we are unlikely to see significantly improved reception. The analogue service here has been good and in my view the digital one should be made to be the same. Why on earth should I have to invest in one of those ugly satellite dishes just because the powers that be cant get it right.

Stuart: Please don't waste your MPs time. The Dover transmitter will have a full power digital service in 2012, as part of the digital switchover. Your MP can do nothing to change this.

Nick Lloyd, Stuart: Fundamentally, you're out of coverage and as far as the broadcasters are concerned, always have been. You will be covered by the Margate relay after switchover.
The terrain blocks clear line-of-sight to the Dover transmitter and always has done - this is why the Margate transmitter exists at all. You're relying on fringe reception which is more likely to be affected by the ongoing switchover programme.
Until switchover, digital takes a major back seat to analogue performance. Some changes to interference levels were inevitable as the switchover programme proceeds, both here and abroad.
The broadcasters are only trying to match the predicted digital coverage to predicted analogue coverage. If the analogue coverage was below the threshold, they are not required to provide a digital service from that transmitter at that location. The commercial muxes are not even required to match that level of coverage.
Margate is fed off-air from Dover for analogue signals and cannot currently transmit digital services, because they just don't reach from Dover to Margate, at least not reliably enough to rebroadcast. Feeding relay transmitters from a leased digital communications line is much more expensive and only done where off-air relay is not possible. It's also very unlikely that there are any spare frequencies that could be used for any interim service.
