Hi there people,
I'd like to put my point here.
I'm a Computer Scientist and Ham radio operator that is entering in this
SDR world. I own a USRP with RFX900, WBX, dbxrx, tvrx, basicrx and

ps: I don't make my monthly budget with anything related with SDR.

I already gave some talks and workshops on free software and open spectrum
in a SDR radio world paradigm, and I always say: USRP is the most
important and significant hardware made in the first decade of the 2000's,
and the Gnuradio is the most important software by the GNU project (I
already said that to Stallman), no doubt!
The USRP together with Gnuradio give us the opportunity to play with the
spectrum in a way never possible before. They allow us to be free in the
area of (social) communications.
I'm currently doing FM RDS, AM, SSB and also receiving DRM (Digital Radio
Mondiale) only using free software! With a software called spark I can
transmit DRM using the USRP. With OpenBTS free cellphone network are able
to exist.

I'm learning how to use USRP and Gnuradio for about three years, and I'm
more excited now then when I started playing with it.

For the Gnuradio and USRP developers: be sure you all are ahead of your time!
; )

Kind regards,
Rafael Diniz
