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.
