For the CW buffs...22MHz JA Marine.
« on: May 09, 2017, 0841 UTC »
Being doing some research into the Japanese fisheries marine CW transmissions, finally sorted out a page in Japanese with some locations and frequencies.  Hope R4002 gets some benefit from my translating as he commented on the fact sheet being in Japanese... ::)

Usually they transmit a brief warm up session on the half hour before the main transmission on the hour.

You will often pick up the word "Gyogyo" in the warm up and main transmission, this translates to "Fisheries" in English.

The ones in bold have been heard by me in the past week. 

A good indicator is the Korean Telecom beacon/marker on 22.611.5MHz CW which is 24 hours, 3Kw to log periodic antenna near Seoul. It sends the following: "CQ CQ CQ DE HLF HLF HLF QSX 22MHZ K".  If you can hear that then the Japanese fisheries will be a good possibility.

22.533.0MHz  CW  JFE  Okinawa  800w transmitter

22.599.0MHz  CW  JFC  Misaki, Kanagawa 2Kw transmitter
22.599.0MHz  CW  JHA  Ibaraki, 500w transmitter
22.599.0MHz  CW  JHC Chiba, 1Kw transmitter

22.605.5MHz  CW  JFG  Shizouka 1Kw transmitter

22.605.5MHz  CW  JFH  Mie, 2Kw transmitter
22.606.5MHz  CW  JFM  Muroto, Kochi, 2Kw transmitter

22.642.0MHz  CW  JFR  Nagasaki, 2Kw transmitter
22.642.0MHz  CW  JFR2 Nagasaki, 2Kw transmitter
22.642.0MHz  CW  JFX  Kagoshima, 1Kw transmitter

22.681.5MHz  CW  JFS  Aomori, 2Kw transmitter
22.681.5MHz  CW  JFT  Kamaishi, Iwate, 500w transmitter
22.681.5MHz  CW  JFW  Iwaki, Fukushima 1Kw transitter

Excellent post. I'm going to use the research & information that you supplied to try to hear some of these.

Nice work, Looking-Glass :D

These guys are running some serious power.  And to think I could have thought CW had been abandoned for marine traffic. ???  Awesome that there's a beacon / channel marker transmitter active 24/7 on 22611.5 kHz.

R4002: The Japanese fisheries seems to be one of the last bastions of the CW mode for some reason.  Quite unusual considering the Japanese are at the forefront of high tech communications and are very quick to move with the times.

The only thing lacking on that Japanese list is the times of transmission (if they were published they would no doubt be in JST), generally I just leave the radio running on a selected frequency at 29 mins past the hour (warm up burst) and at 59 minutes (main transmission) and usually something pops up, propagation permitting.

I have noticed if HLF on 22.611.5MHz out of Seoul is under a strength three the Japanese fisheries stations are not heard or barely audible at that.

They also have other frequencies on the lower parts of HF, when I get some free time will translate and post then under the 22MHz listings.

Strange Beacons: I wonder if you sent off a written or recorded report to them if they would pay you the courtesy of a QSL card?   ??? ::)

JFG heard at 0000z, 0200z, 0400z, and 0430z.
JFX heard at 0030z, 0130z, 0230z, 0430z.
JFT heard at 0330z.
JFW heard at 0400z, 0430z and 0800z.

Interesting. I find the Japanese fishery radio systems fascinating. It's a mixture of HF, VHF low band, 26-27 MHz AM, SSB, data systems on 27MHz, UHF-FM, and of course VHF-FM marine band.  They use CW, and all sorts of data formats. I would love to hear some of the 26-27 MHz AM/SSB traffic related to the weird 26760-27988 kHz / 26.760-27.988 MHz 1 watt DSB fishery radio service or the 27.3-27.5 MHz 25 watt SSB fishery radio service.
