[Lowfer] WOLF!

[Bill de Carle]

Hi John:

Thanks for the WOLF signal!

I first tried using the newer netbook with the SYBA dongle.  Nothing copied.
Then I went back to the old computer using the same WOLF settings as 
last time, and voila:

I'll keep trying to figure out what's up with the netbook.  Your WOLF 
signal is very audible here using the loops configured for SE/NW.
It should work on the netbook - waterfall display looks like peaking 
22 Hz high on netbook.  Something is crazy.  Maybe a Windows sampling 
rate issue.
