If you want to know why they are so loud, take a look at their website 
for a list of the equipment they are using.  Also look at the site map.  
There is info on that map which they have not talked about.  Notice the 
spacing between the two 160 meters verticals.  They haven't said, but 
with that spacing they have to be phasing them.  Then there is the salt 
water. Two phased verticals over salt water on 160 should produce about 
8 or 9 dBi gain at a launch angle of about 7 degrees.  Even at an 
elevation angle of 1 degree they should have about 8 dBi gain.  No 
landlubber is even going to come close to that.
