I think early receivers used an AGC level. Modern receivers use the noise: once the high frequency (above the expected voice bandwidth) content of the demodulated audio drops below a some value, the squelch is disabled. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
