 Hi all=20

 If their kit is that shaky do
 they understand that EM "breakthrough" into the
 long trailing=A0 antenna like cables from the sensors at 37.5
 kHz is possible?=A0 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?
