Do something like this in your RX program: self.filesink = gr.file_sink(4, 'rx_test.dat') self.squelch = gr.pwr_squelch_cc(-55, 1, 0, True) self.complex_to_mag2 = gr.complex_to_mag_squared(1) self.iir_filter = gr.single_pole_iir_filter_ff(0.5,1) self.decimator = gr.keep_one_in_n(4,360) self.logarithmer = gr.nlog10_ff(10,1,4) self.connect(self.u, self.squelch2, self.complex_to_mag2, self.iir_filter, self.decimator, self.logarithmer, self.filesink) Play around with the values you are feeding to the signal blocks until you get what you want. This way, you are saving the (non-calibrated) RSS values of the signal stream you are getting from the USRP to .dat file. Regards, Kresimir
