[hpsdr] What can we do with 2 cards

[Alex]

I'm sorry, but I'm still back on the why not put the connectors on the JANUS

(a) DB-25 to mimic the Parallel port
(b) use some higher density connectors for all the audio. Design a fanout cable like the D-44!

Then there is space on the OZY for the fiber connection back to the host computer to support higher data rates.
Keep the USB-2 for control of the HPSDR, but use the fiber to ship the audio back and forth.
I though everyone was complaining about USB having bandwith limits. USRP is complaining about that problem.

Another couple of thoughts on this:

1) My micrometer suggests we can fit a DB-25S, a DE15S and a USB 
connector along one edge of Ozy.

So, we could create signals that mimic a parallel port and its wiring so 
a standard cable can be used between Ozy and an SDR-1000 for control. 
This solves the "I want to control my SDR-1000" problem.

The DE-15S can accommodate some digital inputs and outputs and whatever 
else is left - reset pushbutton input, etc.  We can define some as 
inputs and some as outputs.  This solves the "I want to hook up my CW 
paddle"problem, and maybe solves a few of the "I want to control other 
stuff" desires.
