I live near winter hill and that's where I normally get my channels from. However after doing a retune I am now picking up channels from winter hill and a welsh transmitter. I am currently viewing channels from winter hill because my digitalstream box gave me the option to choose between them. But the welsh channels are in the 800s. I have taken the aerial lead out and done a blank retune but they are still there. I was worried because I know some parts of the country don't get all channel and I don't want it to effect me.
