i have freeview,
most of the time it is a good picture, with very little problems, but about tea time most days ( even in winter )
an ice cream van comes up my street, then picture goes
all broken, or it displays a sign accross the middle of
the screen saying NO SIGNAL.
My sound goes just for a few seconds occasionally but never been able to find out why. I know i used to get taxis radio on my walkman years ago when they drove past me. I was not aware mopeds had anything to transmit. Just sounds odd that only mopeds effect it.
