Nothing copied for some time now.

Define "some time"?  3 hours before your post they were running 6 to 10 per hour.  There were a couple after 0000z, but before that was moderate / heavy traffic for a couple of hours.  The newbs on several forums were freaking out with statements like "I have never heard them this often" etc.  Of course the traffic level was not unprecedented, but it was fairly active for a while.

I wonder how may get excited when I don't post to the HFGCS Force Directional Message (FDM) and Emergency Action Message (EAM) Log?

P.S. I have had my suspicions for some time now that the folks at HFGCS monitor the HFGCS Force Directional Message (FDM) and Emergency Action Message (EAM) Log.

Not I know of, I don’t often listen to them just once in a blue moon and I wouldn’t be surprised if they move the EAMS to a secure encrypted channel

Interesting, came here to post something similar. I monitor 4724 KHz in the evenings, nothing heard on 8992 or 11175 during the day but my monitoring is spotty. Had thought they might have moved freqs - or decreased tempo ahead of.....?

HFGCS is not going anywhere. As a matter of fact, it is getting an upgrade.

Errr...what?

You said "nothing copied for some time now".  I asked you to define what you meant by "some time".  Note I was asking a question, thus the question mark at the end ("Define some time?"), I was not telling you to do anything.  "Some time" is a little bit undefined, did you mean you had not heard anything in the last hour or so, did you mean you had not heard anything in the last day or so, or were you talking you had not heard anything in weeks?

As for who I think I am, I thought I was a person trying to help you find an answer to your question.

Sometimes, in  a text communications, it can be difficult to judge the other persons intent.  No problem.

Lets keep in mind that I seldom monitor HF-GCS for its own sake, but I monitor other stuff near there (in frequency) and so often I catch HF-GCS traffic even when I am not looking for it.  Call mine a casual, or accidental, observation.  I typically do not log them, but I see / hear them and often accidentally record them when grabbing a chunk of spectrum for something else.

There have been EAMs each day for the past several days.  Yesterday there was at least 6, maybe 10, the day before there was 5 or 6, the day before that there were many.  To the best of my knowledge they were mostly sent on all 4 frequencies, 4724, 8992, 11175, and 15016.  I know that some of them, at least, were on 4724, since I specifically saw that frequency used.

I have noticed that propagation, for me here in the Mojave Desert, appears to have been less favorable for 4724 recently.  Normally that freq is one I can count on, but recently that has been less good than other frequencies.  I am assuming it is propagation, but I suppose it could be a change in the source on 4724.

So it looks to me like there has been plenty of traffic, not heavy, but has been present.  If you have not been hearing it I wonder if it is because of propagation, or possibly hardware issues on their end.

The period of 24 to 27 November 2022 was quieter than usual but still plenty of traffic. Just have a look at my running log:
