I just tested it. I expect to see log scale values of SNR coming out of the estimator block. When I look at this directly using a function_probe and qt_gui_label in grc, I see proper estimates. When I load the file produced by the msg_file_snk into octave, I see incorrect values ranging from e-40 to e+40. I assumed the msg_file_snk stored values as float, so I used the read_float_binary.m script on the file to plot. Are we having a type conversion issue here?
