[hpsdr] Interesting amp kit (maybe)

The datasheet and some application notes for the device are available at 
digikey:

There is some activity afoot implementing amps for 2m based on the 
French article in Dubus (magazine?).  I came across a VK group that is 
actively working on these amps and it was these guys that pointed me at 
the Finnish offering for HF.  The VK blog was pretty interesting with 
some good links mixed in the discussion, some pics of their amps in 
development etc.  Maybe some of these guys can offer more info on device 
characteristics and capabilities, important numbers.  The VK blog is at:
