Roger that. Plowing right ahead with a hacked 1st order PLL filter, here's a screenshot of Sync AM detection rev 1.0, suprisingly works: http://webpages.charter.net/cswiger/AM_sync.jpg the carrier at 7.5k in the upper screen (Voice of Turkey) bounces between 15 and 30db, while the phase locked, filtered and scaled one in the bottom is nailed at 20db. Convert to real and mix yeilds audio. There must be a trivial way to change +7.5kHz to -7.5kHz so we can use complex mixing... --Chuck _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
