Under ideal conditions what kind of range are we talking?
AM = 4-5 miles?
SSB = x miles?

If AM is 4.5 miles then SSB would be 12.7 miles


Nope. Inverse square law, if your twice as far away u recive only a 1/4

of
the signal.



Nope. 3KHz as opposed to 6KHz bandwidth, 3dB gain. .25uV as opposed to

..5uV
sensitivity, another 3dB gain. A useless carrier, a waste of power and

cause
of heat. Sideband vs AM, AM loses.


Yep. Radio waves still have to follow the law, same as the rest of the
electromagnetic spectrum.

The gain is done inside the rig.

BTW, has a raser (radio equivalent of a laser) been invented yet?
