Title: Marine CW channel markers/beacons.
Post by: Looking-Glass on November 16, 2019, 1756 UTC

They are slowly disappearing as the years pass, but there are some still about, most, if not all of the American ones have called it quits, however, quite a few remain in Asia and to some extent Europe.

Some (mainly China & Turkey) are preceded with three or  four "buzz" tones before the call sign in CW is transmitted, the call is only transmitted once. "XSQ" has three buzz tones whilst "XSG" four whilst "XSV" has four "chirps" instead of buzz tones.

The South Korean ones have a standard lengthy format.

SVO Olympia Radio from Greece is 10Kw. Transmits "de SVO" with no preceding buzz tones.

TAH from Istanbul, Turkey is 10Kw. Has four preceding buzz tones then "TAH" in CW.

HLG, HLO, HLW etc are 3Kw to log periodic. Format is "CQ CQ CQ de HLG HLG HLG QSX 12MHz K" as per call sign and frequency.

4XZ in Haifa, Israel has a standard format "V V V de 4XZ 4XZ", often transmits military type traffic.

Be interesting to find out what people are hearing, will start off with some loggings and will add to it and thus build up a list:

22.611.0MHz  CW  HLF 0220z Seoul, South Korea 519 report.

Note:  During late December 2019 and early January 2020 some "XSQ" Guangzhou Radio transmissions were changed to "XSG" Shanghai Radio, whether this is a "shared" frequency with alternating call signs or a permanent change?  Also some preambles have been changed to "de" prior to call sign eg: four buzz tones hence "de XSG" has been noted from late November 2019 onwards.

Thanks Boriken, didn't see your location on your post?  Daytime, late afternoon and early evening propagation picking up here in eastern Australia with 12, 16 and 17MHz getting better. :)

Has any one logged XSG on 16.898.5MHz CW recently?  Have heard the others on this 16MHz section. Maybe it's off air?
