nick : There's no chance of receiving AlJazerra (108) in the Suffolk area anyway, simply because said programme is now broadcast on COM7 which is not part of the multiplex line up at Sudbury.
Of course even if it was, only viewers with TV's or boxes capable of receiving HD transmissions could view the channel as COM7 is an HD multiplex, whereas previously when it was broadcast on COM6 anyone could, COM6 being a standard SD transmitter.

thanks, JB, but why is Sudbury exempt from the new multiplex? It is not a relay, supposed to offer full service. Why also has Aljazeera left us in the lurch by vacating 133?

Why can't you transmit BBC4 HD on the old BBC3 HD channel. Can't be that difficult can it?
| link to this comment |
because Five HD is going to be using this slot but really annoyed we have now lost CBS drama if other channels going to move to com 7 & 8 its best dumping freeview to get freesat

I can get all channels full strength from the Sudbury transmitter bar channel 47. No signal at all, which loses me Al Jazeera and other channels.
This is on 3 different TV's in the house. Signal is boosted.
Could anyone shed any light please?

Jim : Mux 47, if this is what you are meaning and not EPG47? is an HD transmitter only receivable on TV's or boxes fitted with DVB-T2 tuners, can you receive BBC HD on 101?
If though you can, and are meaning that you are unable to view 4seven (47) but can CBS action on (64), then carry out a retune on your TV to update the programme guide, however, if by any chance you are unable to view either of the two then you are not receiving COM6.
Further advice dependant on reply.

I have lost transmission from
C56
C60
C58
C60 and C58 in the last fortnight and C56 as of today 8/5/2016
We had been receiving the programmes on these IMUXs for several years.
Auto tuning on my TV finds only all channels other than the above.i.e.C41 C44 and C47.
It is not the television since both Freeview Boxes in the house suffer from this problem.
I was sent a C60 filter by At800 but this seemed to help as on Saturday when I fitted the filter the C60 IMUX was visible for manual tuning. This IMUX (C60) has now disappeared even with the filter fitted.
What is going on:
1. It does not seem to be a TV problem - both Freeview boxes both 'see' the same IMUXes
2. Does not seem to an aerial problem as we have been getting these IMUXes until recently.
3. Since C60 filter now makes no difference -it is not likely to be 4G interference.
So has anything happened/changed at Sudbury to result in what I describe?
My postcode is CM2 8EB .

The Snail: Whats your signal strength on all the muxes? If some muxes are vanishing, but others just holding on, that points to a possible wiring problem, with some muxes going, but others (even though they might be of the same power) surviving.
Since they are on both TV's (same brand, hence similar tuners?), that points to a common problem, so its likely to be a cable problem from the aerial to where the signal splits. Do you have a booster? And could it be failing?
I suspect that a cable might literally be hanging by a thread....
