Hi all 
 
 If their kit is that shaky do
 they understand that EM "breakthrough" into the
 long trailing  antenna like cables from the sensors at 37.5
 kHz is possible?  i.e. Powerful VLF TX operating in that
 frequency range because of its sea penetrating properties
 for very purpose of communicating with submerged Naval
 Submarines. Or is the acoustic PING encoded to avoid this
 confusion?

  I have been amazed at the
 low tech
  methods apparently being used in
 
  the hunt for the 'pings' from the
 black box of the missing
  Malaysian 
  plane. 
  
  But
 today the BBC lunchtime news showed the Ocean Shield
  search ship 
  using
 DL4YHF's Spectrum Laboratory, presumably with a 96kHz
  soundcard 
  as its input -
 exactly the kit used for the recent amateur
 
 radio 
  transatlantic tests on 29kHz.
  
  Well done, Wolf. Your
 excellent software may help solve this
 
 mystery.
