<<The engineer said that he would instruct the luckless TV viewer to get his set repaired/scrapped >>
I am a radio amateur and when I first became licenced in the mid-70s visits by the Radio Inspectors was commonplace. It was always the fault of the neighbours' hi-fi, radio, TV, deaf-aid, or whatever simply because they were designed to be as cheap as possible - basically junk. Sadly RIs are now very rare - I haven't seen one for about 20 years; hence the little kiddiwinks can go into any radio dealer or pilot shop and buy an airband radio and play at being pilots or air traffic controllers. There's simply no policing of the radio spectrum any more..
