[hpsdr] How many RX channels supported by Hermes Protocol_1 384ksps ?

[ad0es]

Tom,

FYI, I am currently adding a program to the Athena suite that 
establishes receivers and sends the
complex float IQ data produced directly to a grc UDP IQ source.  The grc 
sketch then sends it to
a QT GUI sink for display.

I expect to be able to support 20 or more receivers with this setup.  
The primary problem is finding
enough cycles to display the data after its produced.  If it was being 
crunched as opposed to displayed, I imagine it could support many more 
receivers than that.
