[hpsdr] 14bit Hermes Schematic?

[Martin Emmerson]

Hi Helmut,
   Normally I would agree with you but if you have a new build Hermes board
which has
inadvertently had the wrong (smaller capacity) FPGA installed it would be
nice to see
if it can work with the smaller 14bit firmware before going through the
pain of replacing
the FPGA with the correct one!

I would still be most interested to know what version of the protocol 2
firmware you are
running on your 14bit Hermes ?
I have been trying V10.3...

73's
