Every day in the USA you can hear stations broadcasting using double

(the L-R channel is broadcast DSBSC on a 38KHz subcarrier on the main FM
signal)

(the same stereo method is, to my knowledge, used worldwide)

Very good Doug
Don't know if the scheme is used world wide - good question
Maybe others can confirm

As a second quiz -- what other information is transmitted besides the main
R+L, 38 kHz DSBSC, and 19 kHz pilot carrier ?
