They often have the mixing console set wrong and feed S4481 at times along with EAMs. Also for giggles it was an old (1950s) US Army practice to send voice over fsk, and it worked fine. What I mean is a constant fsk bcast signal was mixed with voice  at the transmitter, the human at the other end just had to put up with the fsk, while the rrty machine ignored the voice traffic and continued to print.

Doing that on 8992 right now.

Odd we can hear everything going on but they can't. Mebbe they're at lunch. Back when USCG had 2 primary hf freqs this went on all the time, could hear some poor rescue helo in the Bering sea calling COMSTA KODIAK with no answer so CAMSLANT relayed comms.

HFGCS is the main player till it is simulated as having been nuked, then E4s and E6s take over - wich is what they are for, with a boomer (SSBN) having been reported in an exercise in 2017. I suppose one would have to keep track of calls heard and extrapolate from there. They (E4/6s and GEP) were also up on UHF MUX and likely the milstar sat system, milstar or a green laser sat being what I expect subs to use for such comms.

i was not going to share this here but i have changed my mind. During the skymaster exercise i picked up an EAM on a UHF freq.
the voice sending the message spoke with a french or french Canadian accent which leads me to believe Canada or NATO participated in the exercise.
