[BC] WLW Superpower Coverage

[Robert Meuser]

I am not sure how Richard is calculating this, but the FCC charts will 
not take you out that far for the ground conductiviy given. The chart 
bottoms at about 800 KM for that ground conductivity. The power required 
for that distance is 50 megawatts more or less. To get out 1000 miles, 
you would have to have a sea water path for that power.
