Don - Thanks for the info. I'm using 3.0.3 since I haven't yet seen instructions for installing 3.1.1 on MingW on the website.

Any advice? What version of GNU Radio are you using? In version 3.0 (and earlier) gr.throttle did not work on MinGW (see ticket 103 in gnuradio.org/trac). It should be ok in version 3.1 and in the latest trunk. -- Don W. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
