?  But the 3db loss for the seven was a modest gain for over 100k active 
amateur radio operators.  .

?  allowing AMers to run c. 3000w pep output while CW ops were limited to 
c. 700w was undoubtedly not equal treatment under the law.

?  So build a G2DAF "Class C Linear".   As long as the splatter is 
confined to the Amateur Radio Service band in use, and interference to 
ongoing emergency communications does not take place, it's perfectly 
legal according to Part 97.
