[Elecraft] KPA1500 design

[David Gilbert]

Actually, a power ratio of 3 is almost 5 db, which is a huge difference 
when you're talking signals near the noise level.  On most HF bands it 
can literally be the difference between being Q5 versus not being 
discernible at all.   If you think 5 db is no big deal, keep in mind 
that the KPA500 offers only 2 db more than that (7 db total) over a 
barefoot K3.
