Hi there. Please see my comments posted today on the DOVER FREEVIEW TRANSMITTER page, concerning Sudbury and the noticeable gradual increase of aerials, in Clacton, pointing to the Dover transmitter.

I am getting the ITV channels in Aldeburgh with an aerial aligned on Dover on channel 49.
I am curious to know the transmitter location. All the possibilities show BBC on this channel and cannot find a map on this site showing all transmitters in Essex and Kent.
Any ideas, please?

nick: I suggest that you are receiving it from Heathfield.

thanks Dave.
How about ITV on channel 26 with Sudbury aerial?
I cannot get any sense out of freeview this time of year. I have a brilliant Sudbury aerial, one minute near 100% signal quality on all muxes, then c56, 58, 60 go to zero, or at least one of them does, then another, then another.
Similar on Dover aerial

nick: PSB2 on C26 is probably Crystal Palace.
Look at the pages for each channel - that is where I'm getting the information from to answer your questions!

Thanks Dave.
I get a good picture from Holland on channel 22 with a group c aerial at 90 degrees to it! Shame I struggle with the right aerial in the right direction for Sudbury!

Dave, please could you explain this.
On analogue, when the foreign channels messed up signals from Sudbury, we had a wobbly picture with foreign picture underneath.
On digital, I lose muxes on c56, 58, 60, but there is no foreign picture to replace them. From this I get the impression that there is no foreigner there, even if I turn the aerial to Holland. So why I am I losing the signal?
Also, when Holland comes in, it comes in with the aerial in any direction. Is this because the signal is bouncing down from above, so that how the aerial is positioned is irrelevant?

nick: The only way that you "might" just be able to view the foreign channel responsible (if!) for your problem is should any of Sudbury's C56-58 or 60 muxes fail, because just in the same way as the muxes from across the water can wipe out your reception from Sudbury, on the other hand Sudbury will be wiping them out.
As unlike in the case of analogue reception and where two signals can be received at the same time without completely wiping each other out, digital reception cannot tolerate its data being corrupted in any way or the receiver will be unable to decode it, and of course this corruption can be starting to occur at well under the level that's is required to resolve a picture anyway.
With regards to the query in the latter part of your posting, basically yes! although its also possible that the signal is beaming in a low level by skipping across the water and is being reflected on some distant "inland" object and back onto your aerial or even a combination of both, but though you are effectively in the realms of the unknown unless in possession of a hand held test aerial (Log) coupled into professional test equipment.
