Oh, no, I was not hoping for full power out with 5W in.  I was just wondering
if I could expect up to 100W out with 5M in (assuming a max 13dB gain), or is
it somehow limited or inefficient with such low drive power.  I would just like
to have only one amp I could use to bring something like a K1 or K2 up to
50-100W and also use to bring a a 40W AM/CW rig up to 800W.

I guess I may just have to wait until the web site announces official specs and
ask when I see them.
