Carl,

Based on your amplifier experience, wonder what you think about driving 
linears with controlled-carrier AM exciters?   I've not tried it myself 
but hear guys on the air all the time running rigs like DX-60s, 
FT-101-series, and even some riceboxes that seem to work quite well.  
The lower resting carrier level would seem to be a way of getting some 
good power out of the lower-rated linear amplifiers like the Warrior.

All I know is that the audio quality can be very good, although it is 
important to set the proper carrier and modulation levels.  Just 
listening to these stations on AM nets, I can't tell the difference vs. 
high-level modulated stations.   I'm guessing that a PEP wattmeter would 
be the best way to set up the combination to  operate within legal limits.
