out of interest, what's the spec of how the data is encoded?  I'm 
wondering if a sound card can decode it.

There's
another problem I forgot to write about. One of the parts, a digital 

band-pass filter made by Maxim, is no longer available. When I get some
time I will 

place the schematic of the board on my website but since one of the ICs
can't be 

purchased anymore it won't be too useful.
  

  

Hi Larry,

  

       Thanks. That would be great!

  

       Maxim produced a new bandpass filter a while back, so I suspect
that there is a replacement. One of the groups monitoring the
ionosphere with VLF radio use it.
