[Elecraft] Linear thoughts

The "KPA1500" should look, feel, and behave like a KPA500.  OK, it can 
weigh a little more but should be liftable by your average age ham 
[oldish].  If you want to sell it widely, the "KAT1500" will also be 
needed since there are a whole bunch of folks who have less than 
monoband stacks on all bands, but it needs to be either an internal or 
external option, some won't need it.

Fans should make no noise whatsoever, even on high speed.  Rated for 
100% duty cycle to accommodate RTTY, JT65, and 75 meter AM looong 
transmissions.  It shouldn't cost more than 3 times a KPA500, same 
$/watt.  It should accept higher VSWR's than the KPA500, say maybe 3:1?  
A plus would be operation on a 20A 120V circuit and/or a sagging 
generator.  Needless to say, full perfect QSK at 110 WPM, zero IMD, and 
be able to eliminate TX phase noise if used with some notable 
non-Elecraft transmitters.  An LCD display for a trapezoid pattern to 
assure linearity would be a plus but not essential since it's going to 
be perfectly linear anyway.

Very tough market to enter, and potential customers can be so very fickle.

PS:  Before blood pressures rise, paragraph 2 is a feeble [very] attempt 
at some humor based on passages on this list.  A deep breath or two 
would be best.  I believe paragraph 3 is true however, and I really want 
to see Elecraft stay in business.
