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.

Nick:

Your reception problems prove there is something wrong with your system. There is no reported problem with the Sudbury transmitter and no one else is reporting any problems using it.

Jo . Some of the Sudbury channels have moved to a lower frequency since the 1st of august . You probably now need a wideband or group K aerial. The retune is because under pressure from mobile phone companies the tv in Britain Europe and America have had to loose some frequencies. Freeview cannot give you a free aerial because your house can watch tv on sky . You will need to buy your own aerial. They can be bought for diy under 50 . Its the cost of an installer that might be 500 though it should be possible to find some one considerably cheaper than that.

I replied to your post on the Bluebell Hill transmitter page where I said -
"According to the postcode you submitted on another post, you may get the most reliable reception from a
Sudbury repeater at Rouncefall (check your DigitalUK predicted reception). Your comments in your post here suggest that the engineer that did your "retune" is not familiar enough with local reception issues since the recent transmitter retunes that have taken place. Either that or he didn't advise you appropriately.
The "problem" with your reception issues from Bluebell Hill are most likely due to interference from other transmitters as more transmitters are now sharing these channels."

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.

nick horrex:

It was considered carefully when the usage of channels was planned. But the main problem you have is that the weather causes signals to travel much further than normal at times of high pressure or high temperatures. As that is a well known natural phenomenon there is nothing anyone can do to prevent irt happening. All you can do is to ensure that your aerial system as as directional as possible, even if that means using a higher gain aerial and fitting attenuators, and siting it so that it does not 'see' the signal from unwanted sources. The aerial has to be very carefully aimed so that any side lobe reception does not include the unwanted signals.

I once had a customer who had a simialr problem and we had a 48 element high gain aerial fitted (they have far better rejection of unwanted signals) and we had to adjust the aim so that it received the wanted signals but not the unwanted ones.

Nick. Its unfortunate that the reduction in available channels forced on the tv industry means that an area like yours is bound to suffer since it is over 50 miles away from a main transmitter. Since you already have a high gain aerial for the high frequency end of the band I think this is the best you can use for getting com7 and 8 from Tacolneston short of using two of them! If you added a small vertically polarised aerial for Alderborough at least you should get good reception of multiplexes 1, 2 and 3.
My situation is similar on the coast so I have gone for the satellite solution .free to air satellite receivers can be had much cheaper than a freesat receiver . (but I don't recommend the really cheapest ones) These pick up freesat channels (plus other satellites if wanted) but just don't have the programme guide. by using a quad LNB head four receivers in four rooms can be used from one dish.

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.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
