Dear LF,
I have recently installed WSPR 2.0 on one older XP
machine and found that decodes were erratic, and the frequency
readout was about 10 Hz high. The reason seems to be that the input
samplerate is about 0.6 % low. The output samplerate is however
correct.
The strange thing is that this samplerate error was
not present with the former version 1.12. I now have the two versions
running simultaneously side by side, on the same machine with the same
soundcard. WSPR 1.12 is producing perfect decodes on the correct frequency,
whereas 2.0 reproducibly shows the described effects. It looks like the new version somehow accesses the soundcard
differently.
Has anybody else experienced this?
Best 73,
Markus, DF6NM
