Dave Laurie: The terrain plot suggests you have clear line-of-sight at 18.3 miles (assuming no obstructions that are on the ground):
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
Also judging by that plot, I suggest that the only likely obstructions could be trees and buildings within several hundred metres of your property. So, has a tree grown, or building gone up or been modified in the time your difficulties started? (Obviously we're talking about possible obstructions in the general direction of the transmitter.

Dave Laurie: I would first double check you are tuned in to the Redruth transmitter, as Caradon Hill would be found first in any automatic search due to its lower frequencies, but wouldn't give as good a signal for the commercial channels.

Go to BBC1, then go your TV's menu, and look for a manual retune or signal information option (could be in retune/installation/setup etc) - and see what UHF channel number or frequency it gives.

Hi All,

How do you check if a wind turbine will interfere with reception of terrestrial tv and radio? A 77m is proposed 380m from my home. I live at TR4 9AU

David Stone: Unfortunately, there is no technical way of being able to check whether it will or not, the order of the day being to "wait and see". However, Redruth is indicated as being the station that covers your area on a bearing of 238 degrees from you, and so you should check if the proposed structure is sited in a direct line-of-sight between the station and you, if it is, then it might possibly have an affect on your reception, the severity of being dependant on the rotational speed of the blades coupled to the weather conditions at the time, i.e: more so during wet weather due to reflections from the blades.

But though, nothing is cut and dried as far as interference from turbine blades is concerned, as so many variables apply.

Falmouth - lost TV signal on Freeview almost completely today - nothing changed in setup, no building works, nothing indicated on engineering; happened a few weeks ago as well and came back after a day, but is getting irritating. Retuned twice. J

john garratt: You've gone through all the things it cant be - which leaves your system at fault. Retuning of course makes things worse - your TV was tuned fine - its just that there is a fault in your system.
