Slightly back on track:
I wonder what kind of AM signal a properly set up FT-102 and amplifier with enough headroom (Henry 8K Ultra, Ulvin Tremendus IV, Alpha 77SX) is capable of? Obviously, you want to loaf both exciter and PA along in when running in AB1, continuous carrier service...and most amateur amps are rated legal limit with a duty cycle less than 100%. In some cases, a LOT less.
Now if I only had 440v 3ph power in here...
