Hello Mark.
Your post has caught my attention due to a shared interest in RF.
I'm interested in software defined transmission and reception, and have some Pis, USRPs, RTL2832 based receiver sticks, and a home-built SDR transmitter (tested on Ubuntu i386, but not ARM) based on a QDUC IC, a MIMIC, and a couple of filters.
Having been a radio engineer for 20+ years, I'm more of a hardware guy, but I can hack together scripts etc but I know little about writing code. however, I am keen to explore the potential the Pi has now that a library for carrying out FFTs in the GPU.
I'd be interested in attending a Pi meet up which covered interesting RF topics!
Regards,
Rash.
