Hi, Here is the quick hack that I wrote a while ago. It probably only works with linux, and be sure that you have all the necessary programs installed (check out README). Just stick some random wire antenna in the sma port and you should hear music. http://mep.fi/viewcvs/fmradio/?root=cvs The

Ah this is exactly what I have been grappling with as well. Basically you need to set the MUX _such that_ you can access the two setting simultaneously. If you have the gnuradio source you, look at the file gnuradio-examples/multi-antenna/multi_scope.py For more than one signal, you can no longer
