[hpsdr] Hermes Connectors

[Kjell Karlsen]

Hi Dick.

Thanks for pointing out this. I think this must be included in the manual.

The marking of pin 1 on the PCB is correct but on the 90 deg shrouded  
header that is mounted on Hermes, the marking for pin 1 is near J27  
according to normal standard.

I think I am a bit responsible for this fault as I was the one that  
suggested to change from the 25 pin D-connector used on Penny (and USB  
Hermes). The "real estate" on the Hermes board is limited and the 26-pin  
header takes less room. We also discussed using a 30 pin header to have  
more I/O´s available but but had to stay with the 26 pin. This explains  
the 30 pin mentioned in the BOM.

It is very difficult to catch every miss and remember, Murphy always rules!

73, Kjell
