[Alberg30] wefax

[George Dinwiddie]

It's been awhile since I done anything about weatherfax, but I was 
successful using a Sangean portable and a simple zero-crossing detector 
about 8 or 10 years ago.  The tuning was pretty critical.  A 
zero-crossing detector is also very sensitive to noise--I'd think that a 
soundcard interface should be more forgiving.  I set the bandwidth as 
narrow as possible to reduce interference.  Portable SSB receivers tend 
not to have good rejection of adjacent frequencies.

You might want to check http://www.hffax.de/ as Marius Rensen has long 
been one of the experts in this.  Anyway, there's a lot of information 
on his site.
