[hpsdr] New Hermes board

[Helmut Oeller]

All proposals, wishes and requirements give a clear profile. We need an advanced Red Pitaya with two 16 Bit ADC/DAC and the approved Zilinx programmable SoC, extended by an audio-codec and eventually a  2/5 W amp. The board would be diversity, undersampling and adaptive pre-distortion capable.  Flexible Nyquist filtering, RX-preamps and other RF stuff can be placed on a little separate board. Estimated cost of components can be below USD 300.-
I’m not kidding. Perhaps this is better approach than a face-lifting of HERMES.

Hi Kjell

I have a small request in the redesign.  It would be nice if you could 
incorporate an output of the the 122.88MHz clock similar to the Mercury 
EXT CLK [J1] and a 3 pin header.  A SN65LVDS1DBVR in a SOT-23-5 is a 
nice small part to do the job.

Thanks for your efforts, 73
