BBC Radio 4 Hid a Control Signal in Its Broadcast for 40 Years

A commenter mentioned something last week I had never come across before. BBC Radio 4 has been carrying a hidden data signal since the 1980s that switches UK electricity meters to the cheap overnight rate every night. Listeners never heard it. It’s finally shutting down this month because the transmitter is too old to keep running. #radio #broadcastengineering #broadcast
