For the past 4 days my DAB radio has been very erratic on FM and displaying NO SIGNAL on DAB, is this due to works on the Preselli transmitter or do I have to get my radio fixed?Thank you.

Hi
I live on the east coast of Ireland In the last few weeks I have lost all signal on channel 42 only all other muxes working fine. I have checked for single channel interference and found nothing wrong. It is also not caused by the weather. Any ideas?

ken owen: If the question is in relation to an aerial already fitted in the loft one which is known to work for standard definition channels then it will be expected to receive HD channels as well. Difficulties picking up HD don't usually arise where standard definition Public Service channels (BBC, ITV1, S4C, C4 etc) can be received.

The post code for Precelly Crescent is different to that which you supplied, it being SA64 0HE. The only way to determine whether something can be received is to try it. Prior to doing this only an assessment of what the likelihood of success might be by assessing potential difficulties such as obstructions.

Lofts aren't necessarily ideal, although in some places aerials in lofts can work. I'm not entirely sure you can be that an aerial in the loft might work. I would suggest that it won't work if you have to point the aerial through the loft-space of a neighbour. The direction to the transmitter appears to along the line of the properties. That said, the road is on a slope, so it might be possible to see over neighbouring properties.

This appears to be in a good signal area. What makes me think this is the prediction from Digital UK and the fact that there is a 10-element (regular size) aerial under the eaves on one of the houses (as shown on Streetview).
