[hpsdr] REV and FWR power inputs Hermes -HPSDR

[Kjell Karlsen]

Hi Tim.

Hermes has its own connector for use with Alex, J15. It is not on the end  
plates of Hermes. Both FWD and REF power are connected via J15.

I do not know the interface for Hercules but I thought it was the same as  
for Alex except it is not having High Pass Filters?????.

73, Kjell
