That is mainly because they are shite. Lil Bruv has one and gets fewer stations than my old anna-log transistor radio.... also he finds the signal comes and goes ~ a bit like good old 208 used to. Strangely his Freeview TV picks up all the duff stations he can't get on his wireless.... We assume the problem is the lack of an outdoor aerial on the radio ~ It's a Roberts BTW so should be good if the price is anything to go by.
