thanks, Hardy, I tried that but was unable to find which CHANNELS were used muxes

does anyone know if the provider of this site still exists? Information re muxes is months out of date.

thanks Mike, understood.
Incidentally, freeview here has been truly atrocious, regularly coming up with 'no signal ' on every multiplex. How I long for the days of 5 channels that worked.

Mike, it is my location, wiped out by interference from abroad. I am by the sea.
However, when they devised this system, they should have thought of that.

thanks Hardy and Mike.
For all my complaining, the situation is marginally improved since the move from channels 58 and 60.
I just hope that this really is the last move. As well as trying various high gain aerials, I make my own. My latest, made since Aug 1 is a cracker, marginally outperforms all others, and easier to design since I only have to cover channels 29 to 47. Nevertheless, when the atmospherics are wrong, ALL channels are lost briefly. For example, if on sd BBC, switching to hd does not work either.
As regards multielement aerials, I have found this not to solve the problem since I believe the foreign stations are coming in by bouncing off the ionoshere, ie, from above.

A question for you re high gain amp with attenuators.
As well as shop bought amplifiers, I have dissected ones which sit behind the tv, [useless things] and put the amplifying part by the aerial and the supply behind the tv. Obviously I cannot link the two by coax, so run a separate wire to the amp.
If I supply the amp with, say, 3, 6 or 9 volts instead of 12, will this have the same effect as a 27db amp with attenuators of different capacities?
The object of this exercise is to avoid buying several different unsuitable attenuators.

Hardy, thank you, you are a very helpful fellow.
Please explain what you mean by a stacked array.
Does a variable gain amplifier have a knob in the room you can turn? I have seen amps with several sockets of different gain, but cannot keep taking down aerial to try each one! No good experimenting at 8ft height in the garden as gain is higher on the roof.
How about connecting the aerial amp to its supply, but between supply and tv using an old volume control?

please would someone tell me where to find an up to date list of the channels used by Sudbury, Dover and Tacolneston?
