Further conflicting data:

Hermes_User_Manual_V1.7.doc<http://svn.tapr.org/repos_sdr_hpsdr/trunk/Hermes/Documentation/Hermes_User_Manual_V1.7.doc>on
http://svn.tapr.org/repos_sdr_hpsdr/trunk/Hermes/Documentation/ also
indicates J10 pin 1 to be inboard.

on
http://svn.tapr.org/repos_sdr_hpsdr/trunk/Hermes/Documentation/ is a Rev A
board and the shows the J10 square pad to be inboard.

I conclude that the documents are based on the Rev A board and the units
shipped are Rev B boards and the pin-out of J10 is reversed.

Can some one please confirm.
