[hpsdr] SDR Cost Comparisons vs Hermes

[jim goldenberg]

Will the new schematic ever be uploaded to the WIKI, or can a bill-of-materials be published?
 

The original premise for Hermes was to combine functions to a single board (lower cost), now look at the picture of the prototype Hermes on the WIKI. It looks similar to Mercury, major components. I believe Mercury currently sells for $469, so then why is Hermes double that price. Only major differences I see are a different ADC, Ethernet PHY and connector, not sure if there is an Ethernet MAC or royalty based IP MAC core, and a new PCB. Do those items add up to $450 of added cost? I don't think it should and if they do then what can we do to reduce those costs? 
 

What am I missing? Maybe the estimate of $900 was just wrong.

Oops, the N2ADR design uses a TI 5500 ADC, not Analog Devices.  My bad....

If you start off with the one critical piece, the ADC, costing over $100 in single
