16990khz USB

[SCPD]

Has anyone heard this before? CW station broadcasting on 16990khz USB @ 2335z

I'm copying bits and pieces but resembles the below listing:

From this site: Shortwavemonitor

16.990,00 hlo seoul radio kor 0821 (10) cw "cq cq cq de hlo hlo hlo qsx 16mhz k 2010-02-15"






Update: I was able to also copy

16910.0 HLJ - PUP'YONG/SEOUL RADIO
16914.0 KSM - MRHS (SF, USA) RADIO

Yes, that is exactly what is being sent on 16990 kHz, at 20 WPM:
"CQ CQ CQ de HLO HLO HLO QSX 16MHz k"

On 16910 kHz, again 20 WPM:
"CQ CQ CQ de HLJ HLJ HLJ QSX 16MHz k"

Not hearing 16914 kHz here at this time.

T!

I guess these are marine radio signal markers for propagation purposes and/or triangulation of location?

It's a CW marker, as was suggested earlier. The CW can be interpreted to mean that the station is listening for traffic on 16 mhz (that's what QSX means); no triangulation involved here (not so sophisticated). Not propagation purposes, either...

Here is the WikiPedia article on Q Codes;

This is within the ITU 16/17MHz cw coastal calling frequency band. If you hear it again try listening to the ship calling freqency, 16734 - 16738.5kHz or working frequency band 16619 - 16683kHz for possible replies from ships. There is a copy of what used to be the Maritime Band Plan at

The coast radio station just broadcasts on his frequency with his callsign.
There will be similar broadcasts on his active frequencies in the marine bands.
Ships have an allocated frequency within a fairly narrow band but not specifically for that coast station frequency.
The operator at the coast radio station is constantly scanning the ships band for calls and as soon as he hears someone calling him, he will turn off his broadcast and reply to the ship.
The transfer of messages will take place and as the coast station is no longer broadcasting his ident, other ship stations will know that he is busy.
As soon as the message transfer has taken place, the coast station turns on his ident again.
Every four hours or so, the coast station will send a "traffic list" with the callsigns of the ships that he has messages for and also weather warnings and forecasts.

Been there - done that! Got the uniform somewhere!
