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?

Thanks for your comment. The problem eventually came down to an HDMI lead between the Freeview Box and the TV. For some reason the T.V. was not reporting the resolution so the Freeview box reverted to non-HD !!

Glad you've managed to find and fix the problem. Also worth noting, HDMI leads should be kept as far away as possible from aerial coax and flyleads as HDMI has been known to cause interference although this was more common with C55, but has been know to affect a broader spectrum of frequencies.

Some manufacturers have been making "grouped" Log Periodics for a little while. Blake had been doing a Group A one for some time.(London - Crystal Palace is the largest Group A region). Once it was obvious that the two temporary muxes COMs 7&8 were not going to be around once the centre frequencies were auctioned, it was a given that Group K was going to be the "new wideband". Aerials that rejected anything above C48 would help with any problems rejecting mobile signals that may cause interference issues to Freeview. Log Periodics have the advantage of an almost flat response across the band.

Thanks Chris.
It seems to me that freeview is going round in circles and that if we had retained the old group B aerials they would have done fine.
i do not understand how they can fit in all the channels nationwide when 48 is now the highest. I recall arguing that Aldeburgh could have been full freeview and was told not enough channels.

chris : The encoders on the PSB3 multiplex are set to switch between 1080i and 1080p dynamically depending on the pictures they are encoding. HD channels on satellite only use 1080i as Sky HD boxes don't support 1080p.

I think he (a different chris) just clicked on the last post comment which then uses the name of the previous poster in the reply, which as it happens was you. Nothing to do with your previous posts, just something he'd seen and didn't know why.
