[hpsdr] Interesting amp kit (maybe)

A most interesting approach.  Was not able to find the IMD characteristics
from a quick glance.  I would be cautious and find out more.  From what I
know, the power output ratings of those high power MOSFET amps from Italy
result from being driven into saturation.  The IMD is horrible if you are
considering linear operation for any reason.  The IMD ratings of MOSFET
devices aren't great in general, unless these newer technology MOSFET
devices are fundamentally different.
