Today I am again receiving the unknown 12.450 KHz signal and also detecting 
 at 
least one other very weak signal with the same data like sound.  I  have 
now 
heard this signal with two receiver.  Also with both loop and  LF TX 
vertical  
antenna.

Hi Dex,
I have never heard any signal on VLF that sounded like that.
It sounds like it is too intermittent to be able to alert
someone else to listen for it if it is only momentary.
 
Is there any rhyme or reason to the times you are hearing
the signal on 12.450KHz? If it was on at regular intervals
I could try to listen for it down here. Otherwise that would
be a good candidate for one of those SDR receivers that
could record a block of reception that could be tuned in
and explored at a later date.
