[hpsdr] Fw: Naive question

Excellent point! Also excellent suggestion. Are there stackable connectors
for the 96 pin connector? There is no reason, that after development on the
Atlas if 'mutual' cards could run 'stand alone' that a stack would be a
great Idea. I had thought of just putting right angle connectors on Ozy and
Janus, but I think everything comes out akimbo!

I had suggested before a SIP type power connector on the Ozy which will
probably be the heart of ANY project. Also the Ozy then could become a
'stand alone' board ala Xylo/Saxo with more capability. Some method of
taking the identical buss and stacking it would be the way to go!

The more we can improve functionality and flexibility of these boards,
without sacrificing project goals, the better!

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.
