[Elecraft] [Elecraft_K3] New from Elecraft: KPA1500 amplifier with built-in ATU, separate power supply

A couple of points.

If you believe that an SWR of >3 necessarily degrades the efficiency of an 
antenna, you are simply wrong.

If the "tuner" components have to be derated to this extent then perhaps it 
should be called a line flattener rather than a tuner because a lot of guys are 
still going to need a tuner.
