The transmitted energy that was formerly packed into 2.5 kHz is now
evenly spread over 100 times that spectrum, so the energy that gets
into my receiver is 1/100th of what it was before. The S9+20 local's
signal drops 20 dB - to S9. Only now he's S9 on 250 kHz of the band,
rather than just a few kHz.

Even if he drops his power 18 dB at the same time he goes SS, he's
still S6 (assuming 6 dB per S unit).

If a station runs 100 W to a dipole at a decent height, and the band is
in good shape, that station will be S9 + 20 over a pretty wide area on
80/75.


So much for SS then. Another problem might be what QSB might
do to that signal anyway....
