Dave,

On a quick look, I see some substantial frequency drift, probably due to the receiver, and also the possibility that your actual sound card sampling rate is quite different from the default 8000 Hz. Both of these things will keep the copy from building up, as the framing keeps changing.

Are you used to seeing frequency drift on QRSS signals? Do you suspect that the receiver isn't stable?

John, W1TAG

Well, easy for some (I can see) but NOT for me. What am I doing wrong?

At least there are a couple of valid decodes there, but my quality fields are way way below those of John's.

Like WSPR another of these toys which I will probably never look at again...
