[hpsdr] 'brainstorming feed'

Good find.  It occurs to me that an area of exploration might be around narrow bandwidth aka coherent signals with lower power single rf conversion.   

Then I went to thinking about full duplex satellites and all the complexity around transponders.

Yes, yes the LTE topic is key and what will drive the research in this area...
