Heh... Well, I was considering operation at 100 watts carrier, 400 watts 
modulated. I doubt my tubes, PS and other tender components would 
tolerate 1500 watts carrier and 6KW PEP long enough for the FCC to even 
be a factor. It would be more like the "FD", as in Fire Department. ;-)

Now you've done it, though... I'll be trying to get to sleep tonight 
around unbidden thoughts of building 4x or 6x GS35B's, or something...

A little more seriously, my comments about duty cycle were geared more 
toward my suspicions about the SB1000 cooling system, or lack thereof.
