Can a 74-year-old microphone last spoken into by King George VI still

be used to broadcast live to the nation? Paddy O'Connell, presenter of
Radio 4's Broadcasting House, thought it might be worth a try.

The answer to the question is

No, it doesn't have a USB interface! :-)

When I was little, I dismantled an old carbon microphone to see how it worked
I just hope to God it wasn't the last surviving example of this.

Only joking, but it was similar, suspended in a metal hoop on four springs.
it had a Bakelite base housing the "induction coil" transformer, I remember
being surprised that the core was made up of many parallel iron wires.

Needless to say, I wish I still had it.
