Hi all,
I've just got an approval from Tom Rondeau that we'll present UmTRX at GRC at the hardware session (we'll be added to the official schedule soon): http://www.trondeau.com/grc2012-dates/
We'll be also doing a demo session at the Open Hardware Summit, showing OpenBTS with UmTRX: http://summit.oshwa.org/
Come visit us there!
