Dear Group: Frank Drake hired me for my first job in radio astronomy.
Years latter, I learned that he was most impressed that I had a first class
FCC commercial license (that type of license is long gone). Did some neat
propagation research in the hills of West Va. (where we did use antennas!)
Prof. Drake had an involved mathematical model that he used to suggest
existence of other people.

The December 1959 paper by Costas made clear the inherent advantages and
disadvantages of wide-bandwidth modulation systems. As others have
observed, narrow bandwidth emissions are most unlikely.

"Dr Drake said he believed that intelligent life DOES exist beyond Earth.

"He reckoned alien civilisations were likely to be far more advanced than
ours and that their analogue TV age probably went long ago. That in turn
means that the world's search for their signals is that much harder."

Maybe they can still do morse?
