I measured the phase noise of the 64 MHz board clock. Looking at the result, I doubt the board clock is producing the phase noise I am seeing in my receiver.Hmmm. The PLL on the MAX2118 downconverter has typical phase-noise specs of around -80dBc/Hz at 10Khz offset. Below 1Khz offset, the phase noise increases to about -55dBc/Hz, which is about 25dB worse than the------------------------------------------------------------------------ ------------------------------------------------------------------------ _______________________________________________ Discuss-gnuradio mailing list address@hidden http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
