I posted this yesterday,  but the heathkit list rejected it, so I'll try again.....

Your typical radio puts out 100W.

200W - 3 db
400W - 6 db
800W - 9 db
1600W - 12 db (if one were to run 1600W....)

It's interesting to consider some commercial linears, such as Ameritron 
(excellant linears).
With respect to the AL-811H (800W output):

AL-811H      800W   $849
AL-80B    1000 W  $1399  1db more for $550
AL-800     1250W  $1825   1.9 db more for $976
AL-572     1300W  $1495   2.1 db more for  $646
AL-82       1500W  $2649   2.7 db more for  $1830

Tube lineup and other considerations notwithstanding,  I can't see why 
anyone would want to buy a linear that isn't 800W or 1500W output.   
You're less than 3 db  (1/2 an S unit)!!

That last 3 db (almost) of gain is very expensive.  Compared to my 3 
element yagi,  for the difference of $1830,  I can get a whopper yagi 
that will give me that 3 db (almost),  plus give me superior side and 
back rejection!!
