[hpsdr] Updated Hermes User Guide

[Kjell Karlsen]

Hi Roderick.

The PCB sold by TAPR from now are the same as the production boards.

The 14 boards I am talking about are boards with the mentioned different  
connection to J16 and instead of scrapping them they were sold out. I got  
2 of the boards and I am going to build them up. They are perfectly good  
enough.

73, Kjell
