[Elecraft] Linear thoughts

[Doug Person]

I'm totally with these suggestions.  A separate power supply that can be 
positioned away from the operating desk would be, IMO, very desirable.  
An internal tuner option sounds nice.  But may be difficult as the 
components for 1500 watts get kind of big.  I think it would be very 
desirable, but may not be practical unless we are willing to accept a 
larger box.

There have been an awful lot of great suggestions.  Most important to me 
are: 2 inputs, 4 outputs.  Inputs are RF sensing. No switch selecting 
needed to transmit from transceiver A or B. Remembers band, output 
level, and antenna selection for each input.

I think a weather proof tuner is a whole other issue.  One I would like 
to see.
