[BC] How would you build it?

[Ira Wilner]

The solid state DX series which is like a high power DAC running at RF 
carrier clocking frequencies is both extremely efficient and very good 
sounding. Heck it could probably pass a 1 Hz audio tone.  I had a DX 10 
running at only 5 kW TPO in a warm transmitter room and I kept the front 
door open to get a refreshing breeze from the box.  One day the owner 
patched in a borrowed audio processor whose output level was way too high. 
At well over 150% positive peak modulation he blew out a cellular 
iso-coupler on the tower effectively shorting out the antenna.  The TX 
didn't mind.  In fact, I believe Harris used to demonstrate that a crow bar 
short would not draw a visible arc because the overload protection was so 
fast, maybe one RF cycle?

Ampliphase was often called Amplifuzz because the uncorrected 
phase-modulation caused sidebands that sound like present-day IBUZ. The 135 
degree vectors were soooo important and, as stated, practically impossible 
to maintain.
