To Mr Moller & all the starving students,
It's not much for the tax-payer or commercial clients. But it's a lot for
a hobbyist.
Why can't there be a open-source community version of a Gnuradio-Hardware,
about $200 for the material, do-it-yourself assembling, some performance
tradeoffs (no expensive MIMO connector, cheap FPGA variant) etc. ?
This is a RX-only SDR with all relevant design files
(Schematics, PCB, Gerber), BOM about $200 :

Evidently Moller's soldering iron is glowing at the moment so we'll soon see
his $200 SDR
sold for the (poor) HAMs and students as a kit in hundreds of pieces....
To those poor students (and Mr Moller):
A few month ago Mr Jamie Morken donated his USRP1 to Jerry Martes for
investigating GOES LRIT/HRIT/EMWIN and POES-HRPT signals
inhope to add more RX examples to gnuradio. It was I (Patrik Tast, FI) who
encouraged Jerry to poke Jamie when he announced an USRP is available.
http://www.ruby-forum.com/topic/203836
When we noted that J "won" the USRP1 I suggested immediately it should be
available for everybody, all seriously should be able to connect to it and
rip GOES/POES data
from it for their theseis and gnuradio developement in general.
We have made a VNC connection to his USRP, I have not only once announced in
this email list that it is available for students <74.100.85.18:1>
As we have seen, none seem to be interested to connect to it and receive
GOES live signals for $0...Please do try to setup your own dish and point it
at GOES and calculate the time & cost it will take you.
All is given for free here, but no interest what so ever....
At the moment we are a 3 man team:
- Jerry Martes @ LA, CA, US: Antenna operator and USRP administrator
- Martin Blaho @ Czech Republic: GR Signal processing programmer
- Patrik Tast @ Finland: GR Signal processing programmer and imager
programmer
As soon as we're done with POES-HRPT & GOES the (Jamie Morken) USRP will be
shipped to the next station
Those who are serious can connect to it using VNC just send me an email and
you'll get the logins.
Patrik (who wonder if extreme USRP usage can be more cheap if you work
togeather....)

matured that time. USRP has been sold in $450 , how one can claim

The copyright is at Ettus. EDA-files are not distributed.
So it's a commercial version, not a community version. At least for the
hardware.
Only the firmware is open-source (using also opensource components
like ethernet implementation).
I alone Estimated its costing on DIGI key and other sites for parts
and PCB sourcing and all
it not exceeding $200 and he is www.ettus.com claiming $150 for
handling n shipping alone.
so outside US it would be around $1000. my apologies if i used harsh
words.

Maybe somebody wants to donate a design to the GNU community?
It won't by a one-way street. I guess the community will continue to
improve
the design after an initial start. Also GNU itself didn't start from zero,
but
used lots of Unix developments to create a free alternative.
