You may find that ypu have too much signal for the Hitachi TV's tuner. A strength of 10 is too much. TV sets vary in terms of their tuner sensitivity and your Hitachi may not like the signals being that strong. Try fitting an attenuator in line with the aerial feed to that TV only. They are available in different 'strengths'so try a 6dB one first. They are very cheap to buy, even the good quality ones are not too costly.

Brian, is Sudbury definitely changing from E to K group in December 2018? and if replacing an aerial now should it be a K type for future compatibility?

john c: If you fit a group K aerial now you will have worse reception on the COM muxes until the frequency changes take place. The best aerials to use for nearly everyone is a wideband type such as a log periodic design which will receive all current and future frequencies used for Freeview from any transmitter. Bear in mind that there is a government scheme to provide replacement aerials for households who loose reception after the frequency changes, so there is no pressing need to replace your aerial now if that is the sole reason for doing so.

After the recent retune BBC2 has terrible break up problems. Before it was rock solid. BBC1 is perfect. Anyone else had the same problem? Sudbury transmitter area.

Abe: BBC1 and BBC2 are both broadcast together on the same multiplex, so that would suggest that your TV may be tuned to more than one transmitter. Please provide a full postcode so we can see which transmitters cover your location, where you are in relation to them and predicted coverage etc.

Prior to the recent freeview channel changes I had every channel and a strong signal. Every channel was approx. 90% and the BBC channels at 100%. But it took me more than fifteen attempted channel rescans to get most of my channels back (not all) but now with poor signals and blocking / pixelated pictures on most channels. For one example Film four is now unwatchable.
What has changed?

Hi,you could check reception with a second hand fv box or overhaul yr aerial system,try a set top aerial and see what local reception condiions are like,sometimes the tuners go faulty after a number of years.Myself,i'm lucky,i live in a swamp area.

Hi,there is another way to improve reception but it is only open to those who can use a soldering iron and are capable of doing work on aerials.n............

Drek Springall: Check the DigitalUK and terrain links - Crystal Palace and Sandy Heath are almost on the same bearing as your original transmitter, but would come up first in any scan - so its likely thats what the tuner has found first. Check, and if thats the case, manually retune.

Hi,one way of improving yr reception is to remove the aluminum dipole which has the coax cable attached to
it and replace it with an insulated thick copper wire,bent to the shape of the dipole,yr aerial should pick better,copper is very good for aerials,as a instance,north of oxford,on a set top aerial, i can get a locked
picture from hannington,abt 40 miles south,before it was 5percent on the signal strength.This is done at yr
risk,NO legal responseibilty of any kind accepted.You might find the signals too strong,worth a try if you're up to it,don't do anything you can't cope with.
