[NLRS] Up to 6 GHz SDRs like Langstone Project

[Thomas Murphy]

Thanks for some of the informational replies off-list. I'm still 
interested in more information if anyone else has it.

I've also started a QRZ forum post to see if I can get anything from 
that audience (though the VHF+ forum is kinda slow over there):
