Marine CW beacons/markers log.
« on: July 19, 2017, 0910 UTC »
The following is a list compiled of known active CW maritime beacons/markers both military and civilian, reception of all are in the A1A mode (CW).  The last date when heard is shown in brackets and other notes.  Please post any new ones heard with UTC date/time, frequency, call sign and report. 

Please note that these are not 24 hour beacons, they do spend time off air.

Stations not heard between 2021 through to 2023 have been deleted, presumed inactive or decommissioned.  Should they reappear they can be reinstated later.

These are observations as of Tuesday 03rd of June 2025:

Japan Fisheries Radio Network:

The JFR Network covers HF frequencies in CW mode 3-22MHz and usually transmit on the hour and on the half hour with a callsign preamble then a request for traffic, there are also current weather warnings broadcast.  If sufficient interest/comment is received I will publish the other frequencies down to 3MHz. 

I have noticed over the past three or so years a sharp decline in traffic being worked suggesting that this service and mode will be retired in the near future, so hear them while you can.  JFE on Okinawa has not been heard for around four years which suggests that this station has already been decommissioned.

22.681.5MHz  JFS Amori, JFT Kamaishi,  & JFW Fukushima. (hrd Jan 2025)
22.642.0MHz  JFR Nagasaki, JFR2 Nagasaki & JFX Kagoshima. (hrd Jan 2025)
22.606.5MHz  JFG Shizouka, JFM Muroto & JFH Mie. (hrd Jan 2025)

17.231.0MHz  JHA Ibaraki & JFC Kanagawa.
17.180.0MHz  JFE Okinawa
17.140.0MHz  JFR2 Nagasaki,
17.132.0MHz  JFS Amori, JFT Kamaishi &  JFW Fukushima.
17.014.0MHz  JFR Nagasaki, JFX Kagoshima.

16.976.8MHz  JFG Shizouka, JFM Muroto & JFH Mie.
16.942.8MHz  JSB Hokkaido.

13.024.5MHz  JSB Hokkaido

12.880.0MHz  JFE Okinawa
12.858.0MHz  JFT Kamaishi & JFW Fukushima.
12.832.5MHz  JFC Kanagawa & JHA Ibaraki.
12.811.5MHz  JFM Muroto, JFH Mie
12.704.5MHz  JFR2 Nagasaki, JFX Kagoshima


HLF, HLJ, HLO, HLW etc Korea Telecom transmitters are all 3Kw to Log Periodic antennas from an area outside Seoul.
SVO Olympia Radio uses 10Kw transmitters to ND TCI 540-2-04 antenna system at Volakas, west of Athens on the coast.
TAH Istanbul Radio, Turkey runs a 10Kw transmitter, antenna system not known, transmitter near Istanbul.
XSG & XSQ China, transmitter and antenna array not known.

China has made quite a few changes in the past year, mostly call sign changes, however, some new stations appeared from July 2022, four new frequencies have appeared (4.210.5MHz, 8.421.0MHz, 12.624.0MHz and 16.850.3MHz) and three had call sign changes with former "XSQ" stations on 4.212.0MHz, 12.613.0MHz & 16.880.0MHz now signing as "de XSG", however, the "de" portion was dropped later around July & August 2022.  It often reverts back to "XSQ" as noted on Mon 06th Dec 2022 at 0530z.

Off particular note is 12.613.0MHz "XSQ" which was noted signing as "de XSG" on Friday 08th of March 2024 at 0740z, however, on Friday 09th of March at 0902z it had reverted back to "XSQ".


Telecom Korea HLO, HLW, HLJ, HLG etc: These HF band CW transmissions ceased on all  HF frequencies during late 2022 and all stations have been officially closed.  Thus they all have been removed from the listings as of March 2024.

For those who collect QSL cards SVO, TAH and HLF, HLG, HLJ, HLO & HLW have issued QSL cards to DXers in the past, providing you send a report in UTC date/time format.  The Chinese stations, as far as I know, do not QSL.

Where time permits I will try an update the list each month.

Any one hearing XSV Tianjin?

The last two known frequencies on 8MHz have been replaced with XSG Shanghai in last few months.

Maybe XSV has been withdrawn from service?

Post please if you hear it with frequency date/time in UTC and report...LG ;)

Thank you Costas, by chance, did you hear 4.331.0MHz at the same time? Interesting to see if they were both on air together, at present 1625z I have 4.331.0MHz at 419 report but nothing on 4.009.0MHz. LG :)

You logging has been added to the main list, thanks again...LG

Thanks Costas, when you have some time please check the following for me as they have not been heard this season:

SVO  Olympia Radio  8.424.0MHz
 
TAH  Istanbul    4.209.5MHz
                       4.560.0MHz
                       8.434.0MHz

I think Olympia Radio on 8.424.0MHz may be off air as I hear TAH on 8MHz regular on 8.431.0MHz.

Appreciated.... ;)

Does any one know the status of the WLO beacons on 4, 6 & 8MHz from Mobile, Alabama USA?  They have not been heard for well over one year, leading me to think they have been decommissioned. Any information gratefully accepted, failing that they will be deleted from the list.

Appreciated. :)
