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.

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!

This changeover is a farce.

Is anybody aware of any plans to broadcast all channels in HD in future as this would have further ramifications for people even with digital TVs (without a second tuner),ie yet another box and more expense even though you are getting more than acceptable picture quality and don't neccessarily want it anyway?

Thanks for all the info herein. I had just complained to Digital UK and have written to my MP complaining about the total chaos of this DSO, my loss of channels and the outright lies which have been propagated. I could not understand why many of the digital channels which I had been able to receive from Sudbury prior to DSO were not now receivable! From this site I have learned that the reality is that this is because rather than being increased as Digital UK claimed the transmitted power of many channels has in fact been reduced. No wonder it is more difficult to receive good digital transmission signals where compared to analogue the transmitted power has been reduced by 150%! Digital UK claim that Ofcom state that the Sudbury power has been increased by a factor of 10 for all channels, which I now know from here is a lie!
The government and Digital UK have told a pack of lies rather than the truth, and those people who have been entrusted to organise this DSO clearly would not be able to organise a proverbial piss-up in a brewery! So thank you for your help in enabling me to understand why the problems exist, and exactly what they are.

Did anyone else lose all signal on these from just before 1am till 1.25am on Sudbury?
SDN and ARQb WAS PUMPING.
