[hpsdr] Fw: Naive question

On the other hand, an Atlas in 300 quantity, which the first run will be is
in the $5-7 range. Hardly a huge sum of money just a little larger than we
need. Cecil once suggested snapping off the mother board at the number of
connectors needed (A little risky from my standpoint!)

Hi,

Although the HPSDR's ultimate goal is a stand-alone SDR, from the point of
 volume/cost curves there are 2 interesting spin-offs for the Janus/Ozy on
the way to achieving that goal:

1. A replacement "sound card" for the SDR-1000
2. A high quality USB "sound card" specifically designed for digital ham
applications in general, able to work seemlessly with all the current
digital software.

Nice advantage to both is they are USB and therefore usable with a loptop.
Although the former may be more easily achievable, the latter has by far the
larger potential from a volume point of view.

 If only using these 2 boards for 1 or 2 above, the Atlas would seem
overkill. Question (possibly completely rediculous, even superfluous) is can
one replace the female euro-connector of one of these boards with a male
connector and directly stack the two boards? There would be issues of
getting power to the boards I guess, but perhaps that could be delivered via
1 of the boards?

Again, may be a totally whacko idea, and I apologize if so, but just thought
I'd throw it out anyway.
