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?

Just seen Elliot's comment and our problems seem similar. Could it be the proximity of the Rouncefall transmitter? Or are we over amplifying the signal?

shame about the low power multiplexes.

bbc and itv ok and on full.

can get the crappy shopping channels but not some of the ones i actually want like Dave.


the crappy channels should be on the real low power, allowing propper channels priority

well thats how is should be

guess its about greed and making money as usual.

I live in SE Essex and when I had a single high gain aerial installed for digital it was pointed at Bluebell Hill. If a bomb went off in Essex I would not know about it as SE TV is only interested in Kent and Sussex.

When Sudbury switched this week I suddenly found that I was receiving BBC East from the back of the aerial on both my TV and my hard disc recorder. My tv then asked me to retune following which I lost BBC East and got BBC South East back again.

My recorder shows two channels Kent and Sudbury and I can move from BBC Se and BBC E.

Since the BBC reception for my area is between Bluebell Hill, London and Sudbury can it be standardised on Sudbury so that we who live in Essex can actually get local news.

If I get my aerial turned round to Sudbury will it be reliable?

Thanks for your reply Brian. I live in Felixstowe receiving signal from Sudbury. Presumably we have to retune again in November to get a full power signal on SDN,Arq A & Arq B. If so, this is not mentioned in your ' Digital Switchover Process' section above. Please clarify.

The 3 COM multiplxes (SDN, ArqA & ArqB) at Sudbury, currently on UHF channels 49+, 54 and 50+, will not go to full (100kW) power until they change to their final channel allocations (58, 60- and 56) on 27 June 2012.

However, ArqB will move to a temporary channel (63) on 16 November this year but, if you can't receive them now, it's likely you'll have to wait until 27 June 2012.

For Linux users, if you are scanning for channels try using the following in the configuration file for uk-Sudbury

T 634000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 658000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 738000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 698000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 706000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE

MythTV refused to scan properly for ArqA and ArqB so they refused to lock, but once I seeded the scanning process with the above, everything was fine and I could generate my own channels.conf file.

Apologies for the typo, the Linux config file should be

T 634000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 658000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 738000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 698000000 8MHz 2/3 NONE QAM64 2k 1/32 NONE
T 706000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE

(Note the 2k value for C49)

Is there a reason why I can receive Arq B channels but not Arq A as it seems to me as if the signal strength for Arq A is higher. On my main aerial I can get all channels fine but it is only on a second aerial at a lower height that I have the problem. What is the "correct" maximum number of chanels that should be available?

Hidey Hi: Mux ArqA is transmitted on a higher frequency which can make it slightly harder to receive. Is your second aerial by any chance a group B, installed before Freeview started? Mux ArqA is the only mux outside group B at present, but in due course all 3 COM muxes will be on higher frequencies, a group E aerial (or wideband) being required for reception of all services from Sudbury. You should have about 106 channels, including radio stations but this can vary according to the content of the muxes being transmitted from a particular transmitter. In overlap areas the way your receiver deals with duplicates and variations can make quite a difference to the number of extra channels stored.

Hidey Hi: Knowing your location would have been of assistance, however the difference in power between these two particular Mux's is in most cases more of an academic one for various reasons relating to the signal path.

The other point is, that although there is a general rule of "the higher the better" for aerials, this however does not always apply in difficult reception areas, as in many cases it more the case of aerial positioning that counts rather than height, this why you are receiving the lower powered Mux better than the higher powered one, albeit of course it not being an ideal position or you would get both!

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
