[hpsdr] Utility to mimic Hermes or Mercury-Metis IQ output

[Jeremy McDermond]

Roger —

I have the starts of “openhpsdrd” for the SoCKit board that emulates an OpenHPSDR rig enough to get it grabbing receive packets.  You should be able to put some file reading code and stuff the packets relatively easily.  You can get a copy from my git repository at:

http://git.nh6z.net/?p=openhpsdrd.git;a=tree

or execute

git clone git://git.nh6z.net/openhpsdrd.git
