Ouch! Thanks for alerting us to that one, Mike. While you still have that rogue LF transmitter (cleverly disguised as a TV receiver), is there any chance of doing some quick tests for future reference? For example: - does the noise reduce when you unplug the TV antenna? - does switching the TV to 'standby' make any difference? - does the noise appear to be conducted via the mains lead, to the house wiring?
