AM electromagnetic waves: 20 KHz modulation frequencyonanastronomically-low carrier frequency

"Ron Baker, Pluralitas!" wrote in message
...

So all the AM broadcasters are wasting money by
generating a carrier?

How did you jump to that conclusion.

Is "DSBSC" DSB?

Obviously, since it has both sidebands. What it's
missing, vs. "normal" AM, is the carrier.
