CODFM (muli-carrier) much better for SETI emissions than modulated CW.

I have done the math in a spreadsheet, and you get a much better S/N ratio.

The current SETI-link-equation is totally blind to multicarrier modulation, as it was derived from CW Microwave AHAT link equations in use in the 1950s.
