How important is this setting as to >its effect on decodes? Thanks in advance for any/all replies. Mine is set to 32 - but Rx is locked to GPS for good long term stability and I let the sound card warm up a long time then key in the exact sampling rate. If the overall drift is substantial it doesn't pay to use a long integration time because it reduces the probability of seeing a sudden (but of short duration) upswing in the signal quality because the averaging process will treat all received frames equally, which implies any one frame with good SNR won't count very much when competing with lots of others with poor SNR. I suppose one could come up with a formula based on expected stabilities at Tx, Rx, QSB periods, etc. Bill
