Only on for a short time - off now. Wide, 'high speed' data. NAA class  
signal level. 24 kHz on air 
at the same time.  First time I've seen a  signal on this frequency. Anyone 
have info?

Hi Jay,
I have heard that signal before several times. I think it is related to  
TACAMO 
(Take Charge And Move Out). It may be a test of the airborne  TACAMO  
system,
which uses an aircraft with trailing wire antenna on VLF. 17.9KHz is  TACAMO
"Channel One."  It is an extremely strong signal here in the  U.S.
