The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. 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?

Joe: Reception of Mux ArqA on C54 is possibly being blocked by a stronger signal from Waltham on Mux D3+4 at 50kW traveling further than normal. When the weather conditions change you should get the ArqA channels back.

Joe: Try putting a variable attentuator inline with your aerial and adjusting if, seeing if it's possible to improve reception of ArqA (E4+1, Dave etc) and even get ArqB back (Yesterday, 4Music, VIVA etc).

For a few pounds it is probably worth a shot:

VARIABLE ATTENUATOR TV SIGNAL REDUCER 20dB 3 5 6 9 10 12 15 18 DIGITAL FREEVIEW | eBay

It may be that the high power signals are acting to desensitise your receiver (reduce its sensitivity) which then makes it unable to pick up the weaker signals.

Attenuating the incoming signals might reduce the strong ones enough to allow reception of the weaker ones. It is obviously a balance that is needing to be struck of which there is no guarantee that it is possible because the attenuator reduces everything, including the weaker signals.

If you try this, then whilst adjusting the attenuator, monitor the strength/quality of ArqA to get it to its best. You will need to give it 10 seconds or so to catch up with the change you have made. Then manually tune to channel 63 which is ArqB. You may find that further adjustment will improve reception of ArqB.

The situation with low power of COM services will remain until 27th June.

Some of these muxes say 'plus 11 others, plus 21 others' etc. How do we find out what these 'others' are? When a channel comes and goes, I don't know if it is my box, aerial, or the xmitter.

Who decides to put rubbish shopping channels on relatively high power and Pick, Challenge etc on low so we can't see them? Can the viewer not have some say?

Does anyone know why so often I am unable to ask a question here? So often I write a question, click 'post your comment' and it says 'there was a fault with your message' and does not send?

In my IP12 location, when I retune the freeview box it finds channels in the 21-28 channel group. My aerial is on Sudbury and I assume it is finding channels from the Aldeburgh group. I know from analogue days that Aldeburgh provided a rotten signal and Sudbury good. How can I stop it hooking on Aldeburgh? And can it, for example, hook up to both so that I find BBC 1, for example, on two different channels?

Nick: The "others" are links and if you click on them it tells you what they are.

Unplug your aerial whilst it is scanning Aldeburgh channels. Scanning is from 21 to 69. If it gives only a percentage, you can work out what percentage to plug in at. 25% should do the trick.

Are we going to be able to get digital radio in the IP 12 area? No signal here without an external aerial, whereas in IP15 it is strong. I believe the signal comes from Aldeburgh, 10 miles away or less in a straight line. Seems a rotten transmitter for DAB, whereas FM Radio Suffolk comes through well from Aldeburgh in IP12. Can't they turn the wick up?

Nick: Looking at the list of BBC National multiplex transmitters, your nearest would appear to be Aldeburgh (1.8kW), Manningtree (5kW), Mendlesham (4.3kW).
