Please do use fixed attenuation, we recommend at least 30dB. The transmit is capable of 15-20dBm output and the receive can be damaged by input above -10dBm Otherwise, such a setup should be possible Jason _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
