[BC] GWEN system...

[Gary Peterson]

" FWIW, back in the 80's we used to lease land at the old WXTR-FM tx site 
in Waldorf, MD to the Army for a GWEN station.  Maybe Eddie or Chip have 
photos to share.  All my stuff is boxed up in storage.
Wonder what its status is today?

While listening for signals in the experimenters' band, back sometime in the
80s, I remember hearing very strong signals on VLF.  They sounded like
several mechanics dueling with air hoses in a large garage.  The S meter
would kick way up and the speaker would emit a loud hiss, then silence, then
another hiss with a different signal strength and a different timbre, then
another hiss, sometimes overlapping a previous hiss.  I surmised it was
digital data of some sort coming from multiple sources.  Many others in the
area heard the same signals.  Someone suggested it might be something called
"GWEN."  Does this sound like the type of modulation that was used by GWEN
VLF stations?  I haven't heard it for many years now.
