Hi Isaac, The USRPs were originally built with the GNU Radio project in mind. Here's probably the first email about the USRP1 in September 2002. https://lists.gnu.org/archive/html/discuss-gnuradio/2002-09/msg00028.html
https://lists.gnu.org/archive/html/discuss-gnuradio/2003-06/msg00010.html links to: https://web.archive.org/web/20030610161838/http://www.comsec.com/wiki?UniversalSoftwareRadioPeripheral Which has the line: "The Universal Software Radio Peripheral (if you have an idea for a better name, let us know)" And the first USRPs for sale. https://lists.gnu.org/archive/html/discuss-gnuradio/2004-12/msg00090.html Reading the first few years of emails on the list is a fun way to spend an evening. Lots of people who are still around in the community or doing SDR in different spaces like Gerald at FlexRadio.
