Re: First appear of the USRP blocks in GNU Radio

Hi!

Thank you for your answers! It was great to see the email for the first USRPs in sale.

I appreciate this information and thanks for clarifying the beginning of USRP's with GNURadio.

Regards

Hi Isaac,

matter of fact: the "usual" distribution method for the driver for the
USRP (1) and later even the early USRP2 were through the "usrp"
directory within the GNU Radio source code, before the drivers were
reimplemented as what we know as UHD.

I don't know at which GNU Radio version these drivers appeared in the
GNU Radio source tree, but honestly, feel free to check out the GNU
Radio releases that we still have[1]: in GNU Radio 3.0.1, there was
already a gr-usrp. Changes to "usrp/" from Eric Blossom, the GNU Radio
maintainer of the time, reach back to 2003-07-30 (see usrp/ChangeLog and
gr-usrp/ChangeLog in GNU Radio 3.0.1-rc1). So, basically I think it's
pretty safe to say that together with the commercially availability of
the USRP1, its interface was available within GNU Radio, probably even
before. Matt Ettus was a contributor to GNU Radio before he made a USRP.

Mind you, GNU Radio in 2003–2005 was quite a bit different – there was
no GRC, to begin with; the Python bindings didn't exist until May 2003,
and knowing SWIG, were probably sufficiently hard to build in the
beginning, so its throroughly possible that people used the USRP within
GNU Radio before building your flow graph with Python became the default
thing to do.

Cheers,
Marcus
