Stewart,

Many thanks for the offer but I have now fixed the problem by using the -r 
parameter to compensate for sound card sample rate.

I tried the method suggested by JIm - the use of the -m command - but got a 
totally inaccurate result that fooled me for an hour.

I recorded M0BMU's test transmission (thanks, Jim - this is a really useful 
service) last night at a lower level than previously but still had no copy. I then 
fiddled about with the parameters until suddenly it all worked. I had to set -r to 
anything between 8090 and 8110. Inside this range it was perfect, outside no 
copy at all. 

Plainly a really good way of being able to set this parameter would be useful. 

I think this makes me the first G station to receive another amateur using 
WOLF. This is hardly an achievement, though as Jim is less than 10km from 
me and he has already been read in the USA.

Is there a web page that details the significance of the figures you see on 
screen before the text? I have found some info but not much that says "this 
should be in the region of . . .", or "if this is below xxx, adjust yyy".

Thanks for the software.
