Hello All,

I have something to show the project which was community developed and
sold in 450$ even though
when it was in prototyping phase and FPGA Atera Cylone used to be so
costly that time coz it was not
matured that time.  USRP has been sold in $450 ,  how one can claim
proprietorship on a product which was  develop as open sourced
hardware  project. many of people have contributed to it on Mr. Ettus
alone.. he ought to bring its price to nominal and reasonable at least
for students when he is producing it in bulk.

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.

Below old mails from Mr. Ettus

Kind regards,

The Universal Software Radio Peripheral (USRP) is a completely free
design, which is now complete and going on sale.  I used gEDA for all
schematics, PCB for the daughterboard layouts, and Icarus for all my
simulation of FPGA code.

I know a lot of people on this list have asked about the USRP in the
past, so here is the official announcement:


        Ettus Research LLC is pleased to announce that the USRP in now
available for purchase!  Shipment will begin in the first half of
January.  For more detailed info on the USRP, check out:


        The USRP motherboard is US$450, and includes a USB cable and power
supply.  The supply is a universal switching type which works on
90-260 VAC, 50/60 Hz, so it will work internationally with a US-type
plug converter.

        The BasicRX and BasicTX daughterboards are also available, for US$50
each.  These boards are perfect for operation with an external RF
frontend, or for prototyping your own.  Each board provides a pair of
SMA connectors for IF signals (either two independent signals or one
IQ signal), and headers for access to 16 general purpose digital IOs
per board, as well as the I2C and SPI buses, and 4 low-speed DAC
outputs and 2 low-speed ADC inputs.

        Each USRP can accommodate 2 Basic RX boards AND 2 BasicTX boards.  A
simple receive only system would require one BasicRX board.  A basic
transceiver would require one BasicRX and one BasicTX.  A complete
system (2 of each) is recommended if you plan to do any multi-antenna
systems or custom development of code for the FPGA.

        Additional daughterboards will be available in the next few months.

        Ordering information can be found at http://www.ettus.com

        Payment is only by check or money order at this time.  A secured
website to accept credit card orders will be online at some point in
the future.  Orders will be shipped in the order received.  Checks
will not be cashed until your unit is ready to ship.  California
residents will need to add 8.25% to the price (not including
