Wellingborough Is there any particular reason why I am suddenly unable to receive Channel 49 in Wellingborough, Northants. It has been fine for 12 months but now I am unable to receive any digital BBC stations. All other channels and stations remain goodDavid WelshTuesday 18 November 2008 9:45AM
Helston Is anybody else in the Redruth transmission area having trouble with MUX B (Ch 49). I can't get BBC 4 or any BBC radio channels.A. WOODWARDMonday 12 October 2009 3:39PM

Since switchover i have to constantly retune my tv to get bbc 1, 2 and 3. Can anyone suggest a reason for this. I am on sandy heath transmitter.KMJ,DerbySaturday 2 April 2011 9:56PM
vanessa: If you are receiving BBC channels on C49 you are tuned to a signal from the Waltham transmitter. The correct frequency for Sandy Heath is C27. If you are not finding any channels on C27 check that your tv or Freeview box is not on the list of equipment that does not support the 8k mode. If it is you will need to obtain a suitable Freeview box to continue viewing after switchover. If your receiver is suitable it may be that the signal from Sandy Heath is too strong.In that case any amplifier would need removing or an attenuator required to reduce the signal strength. Have you tried to do a manual tune to C27? What is the signal strength and quality reading if a signal is found?B AmburyMonday 11 April 2011 6:22PM
Malvern Since the switch over I can't get BBC2 - tried to retune, but still nothing. My postcode is WR13 6AS (Malvern, in Worcestershire). Any suggestions?jasonTuesday 19 April 2011 3:20PM
since the swithover i have lost the block of channels which contain dave, virgin one etc. can anyone help on this issue. I have retuned and had an aerial upgrade but still can no longer receive these channelsColinSaturday 28 May 2011 1:34PM
Troon since the switchover in Troon (KA10 7DW) I get all the channels that is available on my TV downstairs (built-in digi tuner) but my set upstairs which is HD ready does not get BBC HD, STV HD etc,but is getting the other digital channels strongly.
Is it cabling etc as both use the same aerial on the roof pointed towards TROON relay?Mike InclesMonday 11 July 2011 9:30PM
Receiving BBC1 East Midlands on Channel 49 no problem until about 10 days ago. Now nothing. Re-tuning doesn't help, manual or otherwise. Am in Corby, Northants and very high. Can pull Belmont BBC 1 Yorks and BBC 1 East perfectly.
Any ideas please.KMJ,DerbyTuesday 12 July 2011 9:11AM
Mike Incles: Check for single frequency interference on C49. You mention that you are high up, I wonder if you are receiving a signal from Sudbury which changed the frequency of the SDN mux to C49 on 6th July 2011.What is your postcode?- so a check can be made on the trade predictor of what you are expected to be able to receive at your location.Mike DimmickTuesday 12 July 2011 12:41PM
KMJ,Derby: It appears that the Sudbury transmission on C49 was restricted to the west to protect Oxford C5, and that this may have been done by transmitting out-of-phase signals from the lower aerial panels on the west side of the 'digital' mast in addition to the main signals from the top of that mast.
There was no restriction on Mux A before switchover, so it's possible that the out-of-phase signals providing the restriction are no longer transmitted - if that's how it was done.
Information sources: 
Sudbury Transmitter (note MUX3 = Mux A in this table), 
U.K. Television Stations (UHF Digital System) for aerial heights which indicate that there was a contribution from both arrays for Mux 1 and B, and the pictures at 
mb21 - The Transmission Gallery . KMJ,DerbyTuesday 12 July 2011 4:16PM
Mike Dimmick: It would be very interesting to see the radiation patterns for Sudbury, which due to a shortage of frequencies together with a need to deliver a signal strong enough to give reasonable coverage in the face of possible interference from the continent has led to more complicated arrangements for serving the area than would normally be necessary. It would not be surprising if any restriction to protect C5 from Oxford has been lifted with the Oxford switchover only a few weeks away. KTbirdMonday 18 July 2011 7:25PM
I live in London NW5 and cannot get the channels on multiplex 2 ITV1, More4 etc. I believe I had these channels until the other day.
I have done a complete retune but to no avail.
What now, please?Mike InclesTuesday 19 July 2011 9:00AM
Corby KMJ Derby. Thanks for the info. My postcode is NN17 2LQ. Everything else comes in "to perfection" ( as did C49 carrying BBC 1 East Midlands till around the 6th July ). Maybe I should wait for the Waltham "re-set" in August. Anyway, thanks for your reply. Much appreciated.Alan PrydeSunday 1 April 2012 10:33AM
Inverness Is there any known reason why Ch 50 (706mhz)programmes on the Fortrose & Rosemarkie transmitter are running with such a poor signal quality & error rate? All other channels from the same transmitter are sitting @ 100% quality signal, but 706mhz channels are unwatchable due to poor signal quality. I have a clear uninterrupted line of sight to the transmitter. Bob ThurlowFriday 31 August 2012 6:45PM
Since I re-tuned for the Olympics I lose BBC1 & BBC2 when I switch off. If I re-tune again they come back until I switch off, then they are lost again.
