The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. 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?

russ grooms: Its not really possible for anyone to be able to assist without knowledge of your location (pref: post code or one nearby) as the signal levels expected at your location from the various transmitters involved cannot be assessed.

Thanks Norm, but I think I will get the Aldeburgh transmitter whichever way I point the aerial because it is so strong, and apparently the meter cannot be set to look for a particular set of channels.

Does anyone know why several of the commercial channels from Sudbury have to ads etc for Meridian rather than Anglia?

@Nick,
I am on Sudbury and there are no adverts for Meridian, so you are receiving another different transmitter altogether. It would help if you could say what the channels your box has tuned into are.
I suggest that you manually tune to the Sudbury Channels, see the top of this page. On the Aldeburgh page, it looks like all the channels for Aldeburgh are 28 and under, so it's possible that you have a Band A aerial. You will need a wideband aerial for Sudbury and that would explain why you are having difficulties tuning in.
Also, you didn't mention the orientation , but you must make sure that the elements for the aerial are horizontal and not vertical.

@Nick - Congratulations on building your own aerial, it must be very satisfying. However, I can't see how you can possibly expect to receive channels between 38 and 68 (the current Sudbury spread) without a wideband.
I understand what you mean by 'log in' now - I thought you were referring to intelligent tuners which add extra channels based on what has been received, not just checking a value on a signal strength meter.

Hi JB38,
My postcode is ME1. Rochester in Kent. I am told that the signal strength coming out of Crystal Palace is 100%.
Thanks

Hi Norm,
I can't see any mux on the high channels according to the table above. At IP12 I have been experimenting and on a good day occasionally get Pick and Challenge, so not doing badly.
I can't see how an aerial designed for channels in the 40-50 range can be much different from a wideband, which also gets the mid channels better than those at the extremes.

Hi Nick - IN the table above under Transmissions Frequencies, look for "After Wednesday 20th July 2011" and that will show you the channels for the muxes, including 3 on C56, C58 and C60 (and the C60 mux is actually on C63 at the moment until late June).
I suspect that your browser may just not be showing you all the information - does your table appear to stop at C47? If so, try a different browser like Firefox or Opera and see if that shows the channel info.

Nick, Your reception depends a lot on the bandwidth of the aerial. It is possible that your tuning efforts have been targeted at maximising reception in the range 40-50 and that there is a steep drop off in reception strength outside of that. For example, a group B aerial, one that is optimised for channels 40-50, drops off like a cliff above channel 53. In the graphs I have seen (e.g. Aerials, TV Aerial and Digital Aerial their reception strength is about 15db down by the time it gets to channel 60.
If you are buying an new aerial, then go for a log periodic, not a wideband. They have lower overall gain but they have much better characteristics, such as they are less susceptible to impulse noise from badly suppressed ignition systems on cars driving past.

Hi Norm.
I can see channel 54 on the table above. So the wrong browser will leave out info? This is getting very complicated.
Elsewhere it shows arq 4 and 8 on double the power shown here. Do you know which is correct?
My understanding of aerials is that the elements are cut to the correct length for the frequency, therefore all are a compromise as all have to receive on more than one frequency.
A wideband would seem to me to be much the same as an aerial built for the mid frequencies, eg Sudbury. If anyone can explain the difference between these two, I would be grateful.Log periodic would not have enough gain for my location
