Ch. 61 from Waltham Transmitter.
Hi everyone!
I wonder if anyone can help me with a Freeview question I have? We have a bedroom TV connected to an old roof aerial and are in the Waltham transmitter region. We have Sky downstairs, so the aerial is connnected directly into the bedroom television. We are able to get all channels except the BBC ones despite retuning. When selecting BBC 1, BBC 2 etc, the picture and sound constantly break up, making viewing these channels impossible.
In the TV diagnostics page (TV is an LG M227WD), there are five channels:
Ch 29, Signal Strenth 68%, Signal Quality 100%
Ch 54, Signal Strenth 70%, Signal Quality 100%
Ch 56, Signal Strenth 70%, Signal Quality 100%
Ch 57, Signal Strenth 64%, Signal Quality 100%
Ch 61, Signal Strenth 51%, Signal Quality 1%
From my online research, Channel 61 is BBC A and the signal is obviously weak, although I'm not quite sure why if all others are OK. Also from the Waltham transmitter, BBC A has a power output of 50KW, which is greater than the 25KW of other channels, but yet we're still having problems receiving BBC A. I think it may be because BBC A is on a high frequency or perhaps we're receiving some interference on that frequency. I understand from the Waltham Transmitter Wikipedia page that BBC A will be moved to Channel 49 in May. So my question is, will this move solve my problem? Or am I wasting time waiting for a switch which likely will not solve the problem and I need to pay an engineer to replace the old aerial? And by old I'm talking at least 15 years, but it seems to work great for all other channels!
Look forward to any replies.
Thanks very much!

Pre DSO all cahhenls were OK but when they put a mux on channel 60 it would not work even being 100KW.
Since changing the aerial the mux now comes in fine here.
I'd wait for the frequency move if I were you and see what happens.
What is a C/D area?
Thanks!

There Is more about the groups here.
It's worth double checking the cable hasn't been damaged (crushed in a door, plug coming loose) as that may be reducing the signal strength too.
The May change will probably help. BUT this issue may be the first sign of damage to the aerial / aerial cable / aerial connections due to the weather and UV light.
I doubt there is any testing of 4G frequencies as no licenses have been awarded yet. The ch62 issue in Norfolk will be to do with the receiving aerial/cables etc.,. (or water/damage affecting top channel first).
I'll probably wait for the May changeover and see how that goes. But I'll bear in mind that the aerial (and perhaps cabling too) probably needs changing sometime in the future due to its unsuitability for Freeview in this region and possible weather wearing.
Once the May changeover happens, will that be it? In other words, will the channels ever change again, perhaps back to the higher numbers, 61 and the like? I understand no one can never say never, but I guess they won't change again unless absolutely necessary due to the inconvenience it causes to everyone having to retune.
Thanks!

There certainly won't be any move back above 60, as that part of the band is being cleared so that 4G can occupy the vacated spectrum. It is possible that there will be a further clearance in a few years from now (2018 or thereabouts) which - if it happens - would certainly affect Waltham as it's the channels in the 50s that would be cleared, with all TV going to lower frequencies, but that might well be fine in your case as you're picking up ch29 OK. However I wouldn't start worrying about that just yet!
Cheers!

Because of the 'band plan' - there aren't load's of spare frequencies to move to, it's a question of 'trying' to find a channel that won't cause too much interference.
Seemingly not with DVB-T and DVB T2 signals: here on Dover PSB1 is on 50, PSB2's on 51, PSB 3 (HD) 53, COM 4 is on 55, COM 5 59 and COM 6 48 - so we're in the C/D range.
