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....

I am not pleased that Sudbury describes itself as main transmitter yet we no longer get Al Jazeera. This is a misleading description.
I went to a lot of trouble to pick up this transmitter as opposed to our local 'light' one and now it fails to do what it claims.
Why does it not carry the extra muxes?
Why could not Al J start using channel 133 again so we can see it?

In response to the snail, I live in Chelmsford CM1 7DW and have checked this morning and can receive all Sudbury channels except 47 (I don't have Freeview HD). Some in Chelmsford receive Crystal Palace, some Sudbury and some both transmitters; it is very much a street by street situation and I don't know what snail should be watching as we are on the other side of Chelmsford 44m a.m.s.l. and with a good sight line to Sudbury

Nick:

The presence or absence of Al Jazeera does not define a Full Service transmitter. All transmitters carry all the PSB muxes and the Full Service ones carry many of the COM muxes. 'Lite' transmitters do not carry the COM services. Whether a particular transmitter carries any of the optional channels, like Al Jezeera, is entirely up to that particular broadcaster. If they don't want to be carried on any of the muxes allocated to Sudbury then they don't have to pay for it.

Good Morning. This is Richard in Norwich on Monday 6th June, writing at 9:30 a.m. I normally receive my tv signals from Tacolneston, 8 miles down the road from here, however, this morning, I did a re-tune and discovered I had duplicate channels for the PSB 1 and PSB 2 services. A closer inspection revealed that these were coming in on channels 44 and 41 respectively, which must be from Sudbury, more than 50 miles away! This must be due to tropospheric 'lift' or 'inversion' conditions. I wonder how long it will last?

Richard Cooper:

This atmospheric effect usually lasts a few days while the air temperature is quite high and there are conditions to create temperature inversions, others on this site also give information on this natural phenomenon.

Whilst these conditions last you should *not* retune your equipment else you are likely to lose channels rather than gain!

That you found signals from 50 miles away proves it is this effect. Sometimes, signals from several hundred miles away can be received under these conditions. In the 'old' analogue days it caused interference but with digital encoding it tends to cause apparent loss of some signals - which is why you should not retune!
