Richard, are you becoming a 'discriminator' or what?

The most important reduction in radio "static" was made by Edwin Howard
Armstrong in 1933 when he invented the FM broadcasting system. FM
detection can be made very non-responsive to most disturbances,
including variations in signal strength. FM proved its value in WW-2
communications and in broadcasting after the first receivers became
available in 1939.
