Re: [Discuss-gnuradio] Reading I & Q from a binary file

I have updated from CVS and re-recorded a new file using complex types and the gain set to 20. LabView is able to read in any type, so I have defined it to read single precision floats (assuming the first 32 bits are I and the second 32 bits are Q). I have also read straight into a complex ty

Thanks for the new function. I am also interested in a CTCSS function. Couldn't we take the output of your new goertzel_dft function, pick out the particular frequency bin we are interested in by using stream_to_streams and then pass that to the existing power_squelch function? If this makes se

Hello Everyone! Just curious; Has anyone used the 12" coax included with the yagi0900 antenna? It seems like the coax soldered to the heavy antenna(relative to daughterboard) would be hard on the SMA connector on the daugheterboard, and eventually cause problems. It seems like a rigid coax
