There's no law that says you have to run full power output, to tune SWR 
on an impedance matching device...

I'd just as soon use a solid state rig, that has SWR protection in 
it...  slowly adjust the impedance matching device, until you get full 
output of the ricebox, and minimum standing wave ratio.  Then, DON'T 
TOUCH IT!  Just switch rigs, and tune the transmitter to that setting.  
it's resonant.

otherwise, you might be loading up on some harmonic
