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.

And this great information from HF Underground post:

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

From DR:

We used to have as a member, a Japan R/O on a fishing vessel, but he unsubscribed a few years ago.

I remember seeing a "help wanted" advertisement around 2005 for a person with a radiotelegraph license to work at a Japanese Fisherman's Radio station.

There used to be JFA, JFB, JFC, for each of the administrative areas of Japan. Now I believe that JFX or JFR is the last one.

I believe in the World-wide Weather FAX booklet, you will also see a listing for one of the JF? stations.

I do not have a copy of the Admiralty List of Radio Signals (ALRS) but they were the best publication to have on a ship, they had excellent information much better than the ITU books - thanks to our brother R/O's from the UK and elsewhere who sent in the corrections!

CW frequencies listed are:

4630 6421.5 8690 12704.5 17014 22642 kHz

Re: Nations still using CW by VK5EEEVK5EEE, 27 Jul 2018 05:21


Along with Korea the most technologically advanced nations in Asia, and still using CW. Here is what I wrote on 17SEP2015:

I heard JFX on 22642.0 although I found information below, which lists JFR. And I heard the ship station working in Japanese CW with JFX was 7LWK on 22251.0kHz.
Perhaps there are more than one station, as JFX is apparently Kagoshima Fishery Radio and has some common frequencies and perhaps others different according to which lists however also 446 and 500 so must be out of date.

And at 0500UTC and again 0515UTC hand sent CW on 22642.0: CQ CQ DE JFX JFX QSX 12/22 MHZ BK and CQ CQ DE JFX JFX QSX 12/22 MHZ K

Dear Sparks,

the last date to subscribe your partecipation at the MRD 2018 is the 10th April, you can subscribe automatically on:

Also this year there are several stations outside Europe will take part at the MRD 2018. Nobody knows what will be the propagation
condx, so for long distance contacts and to give everyone a fair chance of having DX QSOes during the Event and because 14052 kHz is the most common calling QRG, it is suggested to DX and QRP stations to operate inside a small band of frequencies from 14055 to 14058 kHz .
It is also suggested to avoid calling CQ in "Contest Mode", PLS give adequate time for weaker stations to be heard. So please use the above suggested band as Watching Band reserved to radio stations from far distances.

Best regards,

22nd October, 2017

Another QRP Hours contest is on, this time for 40M only. Please have a look at the contest rules HERE

now I'm convinced that there is more activity on 7030 than there is on 7050 .. ..
so - - what about coming up - this Summer ? ?.

try around 1400 - 1800 in the AESTz
- things seems to be working much better around then.

Re: Activity around 7030 by VK6ISVK6IS, 25 Sep 2017 13:00

it's been a few months or so,
but this afternoon, there was a ZL talking to EA & both side of the SSB QSO were heard.

and both 30m & 20m were alive & well - - on both CW & SSB . .
Italy,, Spain,, Germany were all worked - yah !.

Summer must be coming ..

What have you heard this week?.

Do post, here, what stations that you've heard,
- - That Were Not In Your State .. ..

Just so that others may know, that you heard them,
or managed to get a QSO with them:

and note those contacts - - Here.

So annoying these bloody SSB users on 30m, the band is open for DX even during the day and they go on 10115 wiping out 10114-10118kHz, in the CW band! 10125 to 10135 the new SSB band which is a privilege for VK SSB users is completely unused. We can't ask the whole world to shift up there for CW and skip the prime centre of our CW band just for a few pig headed SSB ops!

I have been preaching tolerance and understanding to allow SSB users to continue to use 30m, I think it is time to change that, as they are not at all observing the band plan and causing QRM. Now that I am back on 30m after a long QRT on HF, I see that nothing has changed, and they clearly have no intentions of doing the simple thing purely because they have been used to having 10115.000 and 10120.000 on their dials and want to resist change instead of having 10125.000 and 10130.000 on their dials. If that isn't pig headedness, what is?

I now side with those who do not believe Australia should have an exceptionalism, especially in these years of sun spot minima when even around mid day we have DX opportunities on 30m. It is time to start logging all QRM and complaining, and to ask for SSB to be removed from 30m. I can confirm that these 30m SSB operators, which I thought were ALL gentlemen based on the conversation I had with ONE of them, KNOW full well about the band plan and are thus being pig headed in refusing to adjust when there is no down side to them, but plenty to us.

there has been some East Coast stations,
being heard - both SSB & CW talking to each other,
but I'm still not able to make contact, with any of them, as a rule.

but, there has been the odd contact, & on CW too :)

Thanks David
I have mainly been using 40m and the condx are very variable at the moment. Yes, the low noise up on the hills is great. Hope to make a contact with you from a summit before long.

Hi Chris, I've seen you a few times on Parks n Peaks, yet to make the contact.

Field radio is a lot a fun and not much RF noise compared to the suburbs.

Over the last few weeks I have become more involved in the SOTA scheme by activating summits.

If you like the challenge of radio operating in the great outdoors, then SOTA is for you. It's also a great way to improve your trip planning skills, test radio and hiking equipment, and improve your level of fitness.

Have a look at the SOTAWATCH website where you can see upcoming activations and the current activity that has been spotted.

My radio gear for portable operating includes a K1 and also an MTR4B - both are CW only rigs.

I have been learning something new on every trip. I'm looking forward to hearing more CW operators out on the summits.

For more info, see:

I've got a new 80m dipole,
so anyone who is on 80m, give me a shout.

my noise level is quite good

Re: Activity around 7030 by VK6ISVK6IS, 28 Jun 2017 04:06

Hi Peter,

I currently don't have any antennas up other than 80m GPA so I'm not on 40m!
What antenna(s) are you using?

77 de Lou, VK5EEE

Re: Activity around 7030 by VK5EEEVK5EEE, 26 Jun 2017 12:22

there has been some activity in recent days,
on both CW & SSB as well.

it's a bit one sided, though, as ES sig are strong,
but mine are not, apparently.

Re: Activity around 7030 by VK6ISVK6IS, 22 Jun 2017 07:44

In the early days of Amateur Radio signal reports were always given accurately, and most often without any exact metering system. Reports were given by ear.

In the last days of Amateur Radio signal reports are often not given at all, no matter the signal strength, 599 or 5NN is given.

The majority of those who give accurate signal reports use the RST system and appear to use it correctly as it has always been intended, assigning the correct number to the situation, more on that below.

A minority of those who intend to give accurate signal reports use the RST system but use it incorrectly: they read the value off their S-meter. More on this below, and why this approach is not correct.

First, let us acknowledge that the actual basis of the Amateur Radio License is experimentation and self-education in communications, and this is the basis upon which the ITU world wide defines amateur radio.

For many of us, we still enjoy building our own equipment, even if only our own antennas, and also the study of propagation. To this end, we wish to receive accurate signal reports. Inaccurate signal reports are not helpful at all.

So what is an accurate signal report? And what constitutes an inaccurate report?

It is difficult to give an entirely accurate report. However, there are way to use and not use the S-meter in the giving of "accurate" reports. First, let us look at the "R" part of the RST system:

R1 = UNREADABLE (Comment: that means TOTALLY unreadable, not even occasional words)
R2 = BARELY READABLE, Occasional words distinguishable

The "R" part of the signal report cannot be measured by a meter on a radio, that is clear. The R is an easy part of the report to give accurately. It WILL be influenced in some circumstances by your ability: your hearing, your interpretation skills, your code skills. It will certainly be influenced by factors such as signal to noise ratio, fading, interference. But there are clear differences between each of the 5 steps:

If you have total arm chair copy it is R5. If not, R4 if no difficulty but ANYTHING LESS than PERFECT COPY. If you have any real difficulty copying, but are still able to copy (even if with repeats), then R3 is appropriate. If you only get little bits here or there, it is R2. If you cannot make anything out it is R1. So the R part of the system is very simple.

So what about the S (Signal Strength)? This is the most difficult part of the system and the one that is, these days, used in different ways, which renders it unhelpful. As stated earlier, some always give it as S9. That is WRONG. Others read it directly off the S-meter: that too is wrong, and here is why:

The S-meter is dependent upon many things: receiver model, receiver settings (bandwidth, notch, attenuator, pre-amp, etc). It thus serves ONLY as a guideline (more on that below) but can be useful in direct antenna-switching comparisons. The wrongful use of the S meter leads a minority of stations to directly read e.g. S1 on the meter, for a signal that is actually around S5 to S7, due to having pre-amp off, and perhaps even attenuator on, and/or a sluggish S-meter.

Just as it is more accurate to decode Morse Code even in the age of supercomputers BY EAR (with an experienced operator) so it is also more accurate to give an S report (not S METER report) by EAR. One has to compensate and consider a number of factors, when doing so, for example:

On higher frequencies, such as 28MHz, the noise level may be virtually nothing, allowing for very weak signals to be heard. On a typical receiver, the S meter at 28MHz is very sluggish, it may not even move until a signal is strong. Many QSO the S meter will be showing S0 but the signal is R5 and loud. If we look at the OFFICIAL S-scale, we can see there is NO S0 in existence, since S0 would actually mean NO SIGNAL AUDIBLE AT ALL:

S1 = Faint signal, barely perceptible
S2 = Very weak
S3 = Weak
S4 = Fair
S5 = Fairly good
S6 = Good
S7 = Moderately strong
S8 = Strong
S9 = Very strong signals

From the official S scale above, we can see very clearly that this is NOT AT ALL intended for direct measurement from any S meter! Otherwise, there would be S0, and there would be options for S9+10db etc, and the scale would not be given in broad human interpretation terms, but instead would be given as a measurement of e.g. Micro Volts etc.

So, returning to the example of a very quiet 28MHz band with a loud signal not moving the S-meter on the radio. Clearly it is not RST509, so what is the actual S value to be given? This is where you can use your experience of your radio, and its response, and also the feel of how strong the signal is: if the signal is NOT barely perceptible, it's obviously not S1. Is it VERY WEAK (S2), or just WEAK (S3)? Is it FAIR (S4) or even FAIRLY GOOD (S5)? Or even GOOD (S6)? You decide, and give the report accordingly.

Another example, on 80m, the S meter may be over responsive on some rigs. Noise levels will have a big factor often on lower frequencies. If a signal is buried in the noise, one cannot give an accurate S report, however, the R report will evidently be 3 or less, and that will give a clue as to the S report being a "wild guess", e.g. "339 LOCAL QRM5" will be clear to the receiving station that the "S3" is only a guess. With strong local noise of "S8" the buried signal may be in fact S6.

Fading (QSB) makes giving signal reports on relatively low powered amateur radio signals difficult, as signals will typically fluctuate by even several S scale levels: a signal could be fading between Strong (S8) and Weak (S3) but usually a fade of one or 2 S points is normal on HF even in good conditions. Thus the amateur S scale is not so practical for general use unless a range is given as e.g. RST539/579 or RST53/79 etc.

This is why the commercial QSA code has only a scale of 1 to 5 making it much easier to give a report unaffected by normal levels of fading: E.g. QSA3, would cover from around S4-6, QSA 4 would cover from around S7-8, and QSA5 covers S9 and "above"… Note that on the S scale, there is NO such thing as "S9+10DB" etc. ONLY S9. S9 means VERY STRONG SIGNALS — no matter that is S9 or S9+60dB. The S meter can of course be used, but it is not the official, standard and intended use of the S scale as in the RST system.

For this reasons, some, including this author, have suggested alternative systems to RST, which can be adopted among regular QSO partners or some nets, to make things shorter, quicker, and simpler. E.g. the T in RST is almost invariably T9. If it isn't, QRI is available: QRI1 means good tone, QRI2, variable tone, QRI3 bad tone. Since 99.9% of T reports are T9 these days, we can safely drop it. The "Q" report suggested at is one such system.

Although radio amateurs, especially if taking the modern understanding of the word "amateur" as being "non professional" are under no obligation to follow any standard, and can do as they please. Thus we have those who can hardly copy you, giving a 599 report, and those who copy you very loud and clear giving a 519 report. But it certainly helps if we are on the same page, and if standards are adhered to. Otherwise, one should create alternative systems.

It has been suggested to create an alternative to "599" for those who don't wish to give a signal report. Meanwhile, if using RST, please refer to the above tables for the PROPER STANDARD. As stated, amateurs can do as they please, and it is a hobby and for most of us it is about having fun. From time to time it is necessary for us to remind ourselves of what the actual standard is, otherwise it gets lost and the majority abandon it.
