[hpsdr] SDR-1000 interface board

[Eric Ellison]

Phil!

Fantastic! This sounds really great! How about Hydra "The many headed
serpent" (Theoretically tying everything together). 

Actually I would even consider buying a new 1 w. Version of the SDR-1000 and
retiring the PIO and enclosure. Between groups, we could probably come up
with an enclosure kit based on some current sleek PC design. This would
probably be a fun project even for non-techies like me! Assemble ALL the
Lego's!

Depending on final design, perhaps this would be inexpensive enough and easy
enough to assemble that we could self fund and produce, like Atlas and
Pinocchio.

Thanks
Eric

I think we can use the same inexpensive $6 CPLD that Phil H is going
to use on his universal IO board to replace the PIO functions.  Along
with JANUS and Phil H's IO board it will make a very nice system all
controlled over USB.

I am looking to see if the instrumentation amp on the TRX board will
be happy with +/- 12 or better +/- 10 volts instead of the current +/-
15.  If happy with +/- 10V we can re-regulate on the PIO replacement
interface board an do some noise reduction tricks with the linear
regulators.

I think that there will be enough interest that we should come up with
a name for this board.  Anyone have suggestions?
