[MilCom] EAM on VLF RTTY

[pdgls]

Thanks for the info David.  Do the ground stations send any transmissions in any modes copiable with something like MULTIPSK or FLDIGI?

 IT was a
 E-6B--they do not do these on VLF ground stations in that
 mode.  The TACAMO aircraft *always* do the 50 Bd EAMs in
 the clear.  Why not, the same message goes out on voice on
 HF and does not mean anything to anyone else.  After 50 Bd
 they go to higher baud wider bandwidth.  When I first
 monitored them back in the 1979's, they came up in CW
 and also used 5 Bd (not a typo) RTTY.
