Thanks John.

I've received you and you've received me.. We can claim a QSO! ;-) (sorry
Mal)

The transmit Wolf comes from a different PC and I set that up by generating
1000Hz tone which I measured accurately, first with a frequency meter and
then by listening to the 50th harmonic! (Diode across the audio)
This one needed less correction, 8004 I think..
I then calibrated the receive PC by feeding the 1kHz straight in.

Thanks also to Marcus for explaining the numbers a bit more. I guess the
f:0.020 means my TX calibration agrees with John's receiver pretty well?
The TX exciter is a Racal MA1723 with an ovened oscillator so it should be
pretty good.

One thing I find a bit awkward about Wolf on an overnight run is finding out
when the periods of good reception were. I suppose you can count up lines
from when you started but is there another way?

Dave,

I did a little better, and congratulations! Copy is shown below. There were
a number of instances of  the "0.020" frequency offset during the night,
some in long strings, but this was the only instance of correct decoding.

Question: Have you set the sampling rate for transmitting? I see that you
were using 8020 Hz on the receive copy you sent me the other day.
