[Discuss-gnuradio] USRP1 + 2 WBX's for sale

2012-01-10 Thread Matt Robert
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

Great, I cant wait for the script, but also maybe we could work on a Makefile so we could update the ports, i'm working on one but cant find tarballs for UHD, the links are all redirects and the tarball name changes, there really should be a "uhd-3.3.1.tar.gz" somewhere. After that just "cd /usr/po

I did a fresh git clone of UHD this morning. Using my script to build it, there was a problem finding Cheetah. After trying the usual suspects, I deinstalled and newly installed cheetah (py27-cheetah-2.4.4). That did the trick although I don't know why. Here is the list: -- #

[Discuss-gnuradio] External Manual control of T/R Switch

2012-01-10 Thread Ed Criscuolo
The RFX (FLEX) series of transceiver daughtercards include an onboard T/R switch to allow a half-duplex setup using the Tx/Rx connector and a single antenna. In GnuRadio 3.3.0, under GRC, the choices for the "Transmit" parameter on a USRP Sink Block seem to be limited to "Unconfigured", "Enabled"
