?  I spoke with a Cal Berkeley graduate about making solid-state output 
radios as clean as the 830.  He said it would be easy:  Simply add a 
low-ohm chip-R in the emitter or source (FET) to create RF-NFB.  The 
tradeoff would be a slight increase in drive power requirement.  Since 
the AN-612 or the MC-1496 balanced-modulator IC can produce ­45db total 
IMD, a 10x cleaner radio is possible.
