[Elecraft] Could the be the basis for the KPA-1500?

[Gary K9GS]

There has been an ongoing discussion on the AMPS reflector regarding the 
Freescale LDMOS devices currently on the market.  A pair of these in an 
HF amp with a 48V SMPS would be an excellent start.....(hint, 
hint...KPA-1500).    I wish I was retired and had some time on my hands :)
