I WILL question that submarines NOW use ANY morse code for
either communications or Alert signalling or did in the
late 1980s. While I've had some contact with DoD on that,
I'm not permitted to say yea or nay. I will point to the
Federation of American Scientists (FAS) website where they
show a diagram with identifying nomenclature of all
equipment in a missle submarine's "radio room." None of
that has any indication of morse code capability.

Len it is my underststanding that one or more of the Navy sub systems
used or at least were desugned to able to use a non manual morse system
that would have allowed for decoding of the signal of the signals

Mark, it is really irrelevant what the USN uses for Alert
messaging to submarines in this newsgroup. "We" aren't
supposed to talk about anything non-amateur...:-)

Suffice to say that those boats DO use code. It just isn't
morse code. Alert messages WERE sent on very low frequencies
using very slow data-rate DATA. The reason for very slow
data rate was signal-to-noise ratio and a very narrow
bandwidth at ELF or even VLF and to allow submarines to
pick up Alerts while still submerged. While ELF and VLF
does penetrate water, water still has attenuation of the
radio signal so the S:N ratio puts a limit at the depth
they can be to receive the Alert. There WAS automatic
decoding equipment in the boat's "radio room" for Alerts.

I used past tense because I do not know what the boats use
NOW. I'm not going to inquire, either. I've got confidence
in the USN and NSA being able to Alert Boomers and Sharks
as needed without fear of being compromised.

I no longer have any confidence that our country's leadership
can use their intelligence reports intelligently...but that
is a subject for a separate newsgroup. :-)

The information on the FAS website (a considerable amount)
is interesting. Whether it represents the "truth" or not
is a subject for the intelligence community's analysis. So
far the FAS has continued to function, stay on-line without
any closures from the government.

There IS some information about the NSA and DIA and CIA
that has been cleared for publication. I have some of those
books. Amazon has them on sale.

But, amateur radio is forbidden by the Commission regulations
from using any encipherment that obscures the meaning of a
communication. Hans has not been forthcoming on lecturing
us on the precise sub-parts on that. Since I am unlicensed
in the amateur service, several others are attempting to
forbid my mentioning anything. :-)
