[hpsdr] Hermes II

Tue Oct 17 07:38:35 PDT 2017

No Apache project!

Published schematics wouldn't be helpful at this status of development. New components will be used and verification of the  targeted data or performance needs a completed layout and physical boards.

Hi,

Will this new Hermes II  be an other apache labs "black box"?.

I think there will be no schematic's or even a picture of the board before you can buy it for big money.
