I have put up a few new videos on my YouTube channel, today they were all associated with the US military, USAF operated, HF-GCS (High Frequency Global Communications System), including what might be the last SkyKing transmission and a rather lengthy EAM.

For those not aware, the HF-GCS appears to have stopped sending SkyKing messages in late 2019. Other message types have continued to be used as before, but it appears that possibly there are no more SkyKings being sent.

What I can say for sure is that there have not been any SkyKings recently reliably reported in the regular forums and mailing lists. There have been some reported overall (such as on YouTube), but on further review of recordings/descriptions, etc, they were either definitely, or probably (in the case of no recordings) not actually SkyKings, but rather miss-identified EAMs. I have not heard any SkyKings myself since October of 2019, and while I don't spend a great deal of time monitoring the HF-GCS, I typically would hear several a month prior to that date.

This is my last recorded SkyKing, and I have not yet seen a confirmable more recent recording.

Only time will tell, but has the SkyKing message format on the HF-GCS gone the way of other Cold War signals?

A rather lengthy EAM, of 164 characters. To be sure, I have heard longer EAMs (the longest I have completely recorded is 278 characters, but I have heard the tail end of one over 300 chars), but this is definitely longer than average.

And a recent format SKyKing transmission from a couple years ago. I included this video in the channel only because tomorrow I will release a video of an older format SkyKing, a format that they stepped away from in about 2016:
Military station, US HF-GCS, Skyking signal, recent format, 4724 kHz, 13 December, 2018, 0207 UTC
