it is possible to communicate over very large distances with tiny amounts 
of power (with a human listening to the static on headphones, picking out 
slow morse code from the noise)

so you understand, 1uw is one MILLIONTH of a watt.  720nw is 0.72uw

so basically, this is telepathy.  The brain uses about 20 watts just 
sitting there by the way.

these are the records:

3.5mhz 27uw N2XE-

1uw record 28mhz
According to Rich Arland, K7YHA (now K7SZ), in World Radio magazine (Feb. 
1990, year 19, issue 89, pp. 46-47) the long-distance low power record is 
held by KL7YU and W7BVV using one micro-watt over a distance of 1,650 mile 
10-meter path between Alaska and Oregon in 1970.

While the "absolute" world record seems to be 720nw on 28mhz
