I'm a bit confused as to why that is - I'm calling it with MC_WE_LOCK_TO_SMA which is defined in usrp2_mimo_config.h - it basically comes out as 0x0001 (i.e. _MC_WE_LOCK | 0, where _MC_WE_LOCK is 0x0001). - -- Doug Geiger Research Assistant Communications and Signal Processing Lab Oklahoma State University http://cspl.okstate.edu douglas.gei...@okstate.edu doug.gei...@ieee.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Cygwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJnwaQgfOzzR5bXIgRAi2hAKCBOY2ijc1wo2MF/jFBRAEAqQpCigCgsEeS xqHAjKz3SoLMYFG4JK2sefo= =+Ulx -----END PGP SIGNATURE----- _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
