Hi.
I found I am receiving a weak analogue Channel 4 signal on UHF ch. 63, but this map doesn't appear to show any analogue Channel 4's in the area.
I thought it would be a relay of Sutton Coldfield, but none of it's relays appear to transmit 4 on 63. Any idea where could it be from?
Thanks.

Stuart O.: Sometimes the map doesn't show all the pins, particularly if you're using Internet Explorer, but in this case, I can only find one site that ever used C63 for Channel 4 - Glenridding in the Lake District. This switched over in July 2009 and no longer uses this frequency.
I searched the list at http://www.wolfbane.com/articles/uktv2.htm
The only things I can think of are that it's the RF output of a Sky or Freeview set-top box (yours or perhaps a neighbours, if you're sharing an aerial), or if you're using a communal system, a system where the channels are transposed to different frequencies. This is usually done if the signals from the transmitters are strong enough to be picked up directly by cables within the flat, which then arrive at different times from the signals received at the aerial, causing ghosting on analogue (and, likely, errors on digital).
If your TV, aerials or cables are very close to a neighbour's equipment, and that equipment isn't well shielded, it could be picking up a tuned version - but you'd expect it to change which channel is displayed when they choose a different channel! (RG47SH)

We are on the Sudbury transmitter and do not receive ch 63. I believe this is due to very low transmission power and that there are plans to increase this soon. Could you please tell me when this is due to happen so that I can re-tune.
Thanks
