A great many years ago I was working at an ATCRU when a gentleman from the GPO (yes, it was that long ago!) demanded to check all our transmitter equipment to make sure it was within 'spec'.
"What's the problem?" we asked. It appeared that someone in a nearby village had reported us to the GPO as some of our transmissions were breaking through on his TV and interfering with 'Ena Sharples'!!
The GPO chappie confirmed that all our kit was OK, so we asked him what was going to happen now. He gaily announced that he would nip round to the complainant ...
... threaten him with a summons for illegally intercepting ATC communications and tell him to get another set!!
