Korean Coastal Station HLO 16989 kHz morse error

[FFZ]

Has anyone noticed that when this automated beacon IDs, it sends HLO HLO SLO.  Sounds like their message has an error!  I've listened to it quite a bit lately and wasn't sure if QSB was causing me to miss a dit, but now I'm certain it's an error in their message.  Have a listen on 16989 kHz; the "wheel" sends "CQ CQ CQ DE HLO HLO SLO QSX 16MHZ K".  I'll post audio later on....

Hi,
I've been on 8484(U) since 15:00UTC - twenty minutes now - and there is a signal that sounds like extremely s-l-o-w morse. Any ideas what that could be. Interesting though not terribly exciting!!!!

Many thanks for the info. I'm just getting back into shortwave after a 33 year break!! There are a lot of interesting things out there that I didn't tune into back in the early '80s. Is this very slow morse normal for them? Cheers...

I made a ten minute recording of the signal I was listening to on 8484(U), to try and decipher it. The length of each tone varies between approx 1 second up to approx 11 seconds, most being 1, 2, 3, 4 or 5 seconds.

Here is a part of it (hopefully the tone lengths are accurate!!):
2,2,3,2,2,3,3,3,1,3,2,2,2,1,4,3,1,1,3,1,5,1,7,3,2,3,2,5,2,6,3,4,2,4,4,4,6,3,2,2,1,3,2,1,1,2,1,1,3,3,5,4,7,4,4,3,4,6,2,2,3,6,6,2,2,5,5,2,2,1,3,2,8,5,3,1,3,4,4,1,3,4,6,2,3,1,3,6,7,4,2,2,4,2,2,6,1,2,6,6,2,3,4,4,8,3,2,2,1,8,4,1,11,1,3,6,6,2,4,3,3,5,2,5,2,5,3,3,3,2,1,5,4,2,1,7,3,1,4,6,1,3

Any explanation of the the length of the tones would be very much appreciated....
