Telecom Korea runs these markers/beacons with generally 3Kw to a Log Periodic antenna from Seoul, South Korea.

China has a number of similar beacons except preceded with "buzz" tone then callsign, scattered from 4 to 16MHz various locations in China.

I use them as propagation indicators due to their reliability as "always being there"... :D

Thanks L-G, will keep an ear out for the Chinese ones on this side of the Pacific pond.

For your information:

Chinese CW beacon/markers:


VRX  Hong Kong
XSA  Nanjing
XSG  Shanghai
XSH  Dong Fang
XSI  Sanya
XSL  Fuzhou
XSQ  Guangzhou
XSR  Haikou
XST  Qingdao
XSV  Tianjin
XSZ  Dalian

The complete set of Seoul Maritime, Telecom Korea, all 3Kw to Log Periodics as follows:

8.483MHz  CW  HLG 
8.484MHz  CW  HLG
8.484MHz  CW  HLO
8.636MHz  CW  HLW

12.843MHz  CW  HLO
12.843MHz  CW  HLW2
12.916MHz  CW  HLF
12.917MHz  CW  HLF
12.923MHz  CW  HLW2
12.923MHz  CW  HLO
12.935MHz  CW  HLG

16.910MHz  CW  HLJ
16.990MHz  CW  HLO

17.130MHz  CW  HLW

22.611MHz  CW  HLF

If you are interested in chasing a QSL card Telecom Korea does issue cards for confirmed verifications of reception, can pass the address on to you if required.

Be interesting how many Chinese and South Korean marker/beacons you can log from 4 to 22MHz!  Good luck... :D

Interesting that some Seoul Maritime frequencies are still in use since this March 1979 Speedx listing:
HLF 4273, 6344, 8484, 12916.5, 17079, 22395
HLJ 8497, 12727, 16910
HLG 4308, 6451, 8473, 12935, 17118, 22482
HLO 8577, 12843, 16990
HLW 8636, 13005.5, 17130
HLW2 12923
HLW3 12712
HLX 13028

Could not find: HLJ 12727kHz, HLW 13005.5kHz, HLW3 12712kHz, or HLX 13028kHz but of course that's a very old list.

I think you will find that many of those frequencies you listed, and some of the callsigns, are now inactive.

Telecom Korea went through a huge range of reforms and streamlining in the mid 1990's which seen many services terminated.

I would not rely on March 1979 listings, so much has happened technology wise since then and many HF services replaced, especially CW ones.

The ones I have published came from Telecom Korea website earlier this year and all published have been logged this way.

An accurate list of the Chinese ones is hard to come by.

Good luck in chasing them.

There are South Korean fishing vessels still using CW.
The Sajo Oryong peskies net can be heard on 4100 kHz USB voice / 4101.4 kHz CW.
They have been recorded and copied recently sending in Korean language CW code.

Do any of these countries operate shore stations using CW on the 25 MHz or 26 MHz ITU marine channels...or are they limited to the lower bands of 4-22 MHz?  Do they still use the MF frequencies that are popular in Europe and elsewhere for marine? Not including the country-specific 26/27 MHz "marine CB allocations" (of which there are several - https://www.hfunderground.com/wiki/index.php/CB#Japanese_27MHz_Double_Side_Band_DSB_Marine_Fishery_Radio).

If anyone could provide a link to a table of Korean CW code, not the SKATS code, it would be appreciated.
