Hi All, I have a USRP1 system for sale. It contains a rev 4.5 USRP1, and comes loaded with two WBX transceiver boards (50Mhz - 2.4GHz) It is in immaculate condition and works great. Reason for sale is because I own two of them and the research project I bought them for has been completed and so I

2010-06-25 Thread Matt Robert

[Discuss-gnuradio] USRP1 Clock drift

2011-01-06 Thread Matt Robert
