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
