Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Roger Sharman: There are no faults showing for the Sudbury transmitter. You may have been experiencing interference from distant transmitters as is common with the current weather conditions.

Hitachi model L19H01, says it finds 139 channels, but no 2,24, nothing between about 271 to 711 (no e.g.601 red button) ok until about a week ago. Retuned several times, and tried without ariel to clear all channels as well. Anglia (Sudbury transmitter) Other tvs find all.

r green: Please provide a full postcode so we can see where you are in relation to the transmitter and your predicted signal strength etc. Are your other TVs connected to the same aerial? If they are (and if practical to do so) take the TV with missing channels to one of the working ones and connect it to the aerial and retune to restore the missing channels. This will confirm if the fault is with the cable from the aerial (or splitter/amplifier if all your TVs use the same aerial).

r green: Kesgrave ip5 2nz. Retuned using socket supplying main tv. signal strength reported strong at 10. Main tv and 2 others have no problem finding eg 601 or 2.
chanel list is about 110 instead of 139 which the other tvs find.

r green: That all points to be fault being somewhere in the cables or connections between the splitter/amplifier and the point where you are loosing channels. Do you know where the splitter/amplifier is that all of your aerial sockets connect back to? Try swapping the cable from that socket to the TV with one from another socket that you know works. If the problem remains, unscrew the socket and check the cable is fully attached on the back and that there are no loose strands of the outer metal braid or foil touching the inner conductor, causing a short circuit. If that looks good, go to the splitter/amplifier and try swapping the cable from the point where you are missing channels with one that you know works. If the fault remains, you have further confirmation that the fault is somewhere within that cable rather than the splitter/amplifier or anywhere else.

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?

StevensOnln17:29 PM
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.
