G'day All,
When soundcard switched to 48000sps (was 44100sps) the 'non-decode of strong signals' behaviour disappeared. Apparently the soundcard XP OS default driver does a better job of downsampling from 48000sps to the 12000sps WSPR sample rate as they are harmonically related.********* THIS PROBLEM HAS BEEN TRACED TO WSPR NEEDING A SOUNDCARD SAMPLE RATE OF 48000SPS.**********
All is working fine except the strongest signal (ZL2FT) has never decoded here despite my setup being able to decode stations >15000km away at -17dB levels.
Tried varying the Dsec but to no avail.
Any ideas ?
Cheers
