[hpsdr] New Hermes board

[Helmut]

Hi guys,

I think it is evident for all, what Kjell plans: a ‘simple’ redesign of Hermes as it exists, just extended by a 5 W onboard amp and an additional undersampling frontend, and produced somewhere in the world under economic conditions. All other desired and certainly justified features would be a critical overload. Don’t forget that we even have no stable protocol 2 firmware version for the original 16 Bit Hermes design yet. The handmade UDP in the FPGA seems to be the Achilles heel.

G'day Kjell,

many thanks for the information.

One feature on my wish list is an interface to provide a means of 
coherent phase reception for MIMO, beamforming, DF etc. applications, 
which, AFAICT, is not possible with the current design.

After a few weeks playtime with LimeSDR, I've started to appreciate 
streaming of 30MHz BW of spectrum and the ability to select and decode 
multiple channels, something I would be looking for in the next edition 
of Hermes.

73, Berndt
