Hi I live in Braintree, Essex (Post Code Top Right). My problems are with Com 5 it seems, everything which is transmitted on Com 5 is picxulatted and making the popping noise. In Braintree I am pointing at the Sudbury Transmitter. 2 of the best channel are on Com 5 (sky sports & talksport radio) and can not get them.
I live in a block of 4 flats which has a massive pole one end of the building with the aerial at the very top of the pole, followed by other aerials about 3 or 4 in total, think one maybe a radio one and a digital dish at the very bottom, this is maintained by the local council contractors, so not a lot of hope there. all the aerials are fed through to cables into each flat. I have tried a boaster inside but with making no difference.
Is there anything I can do to cure this problem.
Thank you for any help you can give.
Andy

Andy Bradbery: Have you checked with any neighbours in your building to see if they are experiencing the same problem. If they are, it's unlikely that there's anything you'll be able to do yourself so it would be a case of contacting the council and asking for it to be investigated.

Braintree is quite close to Sudbury . it maybe that com5 is too strong . I would try an attenuator . An alternative is to try to receive your programmes from Crystal palace instead of Sudbury. A wideband aerial would probably pick up Sudbury and crystal palace . Doing a retune to avoid picking up Sudbury you can unplug the aerial when the autotune scan gets to UHF channel 30.

Hi
Last night 1.6.2017 I lost freeview television reception.
I was still able to receive free sat but my recorder is freeview so unable to record or watch free sat tv.
This morning everything appears to be back to normal.
My question is was there a broadcasting problem of some sort last night.?.?
Thanks
Roger

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.
