The 30m CW interest group encourages CW activity on 30m to ensure we do not lose this very special prime CW band to other modes, nor to other primary services. The best way to do this is to be active on 30m as much as possible.

30CW.net membership is open to CW operators who use or wish to use the 30m radio amateur band using CW for "non-5NN" activities and who support the specified aims below:

  • Promoting human CW QSO activity
  • Giving meaningful true signal reports
  • Encouraging newcomers to CW and 30m
  • Retaining bottom 35kHz for no-contest CW
  • Defending the traditional CW operating codes

If you agree with the above aims, please join this site via the button below (visible before joining/when not logged in), taking care to register with username of or including your CALLSIGN otherwise you'll need to go and change your "screen name" in settings.

In my view, the best overall tool is www.lcwo.net — I am using it as a key stone to a class of 10 that I instruct, free of charge, in an effort to promote CW. They want CW to pass their HF or upgrade licenses, but I'm confident those who remain at the end of the course will have a love for CW and be able to have real QSO and QTT.

Here are graphs which show that interest in learning and improving CW skills is on the rise over the years and now accelerating: https://lcwo.net/stats

With big thanks to 30CW31 Fabian DJ1YFK who created and maintains LCWO.net.

Learning (or improving) CW by G4OJWG4OJW, 09 Jun 2021 04:15

Good news! I have an Email from PKX confirming they are still active on 500 kHz! I'll try to obtain more information.

Thank you OM Gene I also added it to Clubs list of frequencies now.

Re: 30m beacon added by G4OJWG4OJW, 08 Jun 2021 08:12

Hello together,

fyi,
I have added the beacon IZ1UHA/B under 30m info — Propagation.
Reception reports are listed on his qrz.com homepage.

Actually the CS is not easy to get callsigns for the alerts, your list is very helpful. How you manage that? Must have been a lot of work. A pity the rbn site has no alert for members. Nice when CW announces alert. Seems only way is to paste your above list in.

Here https://www.itu.int/mmsapp/coaststation/one/2740 is listed UFV on 500 kHz and UFZ on many HF maritime CW frequencies, is this still the case of being active?

Also some years ago found listing of some Chinese stations (XSV?) on 500 kHz.

And just by random searches — it takes a long time there is no easy global search — I found XYR in Myanmar listed on 500kHz and XYR2 on 460 kHz both with 3kW: https://www.itu.int/mmsapp/coaststation/one/463

Wait… I found https://www.itu.int/mmsapp/coaststation/list if you don't select any country and just enter frequency 500 and unit k:

Took me a long time to copy/paste this all, hopefully we can verify if any of these may still be either active on air, or licensed and ready to be on air if required:

Thanks again Pierre, no there's no government in the world good enough for me to work for them :-o) maybe in a future world if we survive this one?

Some additional thoughts as this becomes clearer…

On HF there hasn't been in the amateur bands any CW calling frequencies, the concept of call and then QSY on establishing contact has never caught on nor was there a need to when there was more activity.

That doesn't mean we cannot try and with success on some bands, notably 40m 7050 was a success in Australia, as seen at www.vkcw.net/7050 but on DX bands this is more difficult.

Objections by detractors will include:

- There isn't a need (but we feel there is for the reasons we've given)
- No one owns or can reserve any frequency in the amateur bands
- Only a minority will get the idea so it won't work as majority don't participate
- On 30m a fixed frequency isn't a good idea due to being a secondary service
- What about when there is QRM on a frequency (even "birdies" local QRM etc)

With the above in mind, and also the difficulties involved in establishing such an idea, I offer the following modifications to our broad idea above:

For 30m: we adopt the QTT idea see the entry at the bottom of the Clubs Frequencies list, i.e. 101UTCDATE.5kHz +/- QRM. The idea there, could be adopted to avoid the problems about QRM and primary users possible occupation. And adapted to maybe just QSY on establishing contact among those consenting?

For 20m, 15m: calling frequency 0.5kHz below top end of band, with QSY down 1 etc. Especially useful during CW contests, less so during SSB contests (in theory the highest USB frequency to be safely used is 14347.0 and 21447.0 but not all understand this). There would be slight cross-mode QRM but not much if SSB using those frequencies. But this could be adapted to even those 2 SSB frequencies being used as standby.

For 40m, given that LSB is used, it's harder to use the very top of the band, as SSB there would cause more QRM and vice versa. Perhaps adopt the same idea as 30m.

For 12m and 17m, finding an easy solution is more tricky due to the unusual band allocation in terms of kHz numbers. Perhaps 0.5 kHz from the bottom of the band as calling frequency?

For 10m is also very tricky, given the huge size of the band. Using 29699 wouldn't seem sensible, 28000.5 is likely covered by CB using 28000, 28500 is SSB usual calling area, maybe 28050.000 simply be adopted as it is more likely to be used and good for unexpected openings etc.

But we did say we'd start off with 30m. Maybe that can be adopted for 30/40 as above suggested, varying by the date (UTC date).

For me setting up via internet is much easier said than done, so will have to pass there. I think higher bands will become more interesting as time goes on in the solar cycle, e.g. 17, 15, 12, 10m, and for those bands a ground plane may be more doable or a half square, if you're having antenna space problems.

I agree, too much technology, maybe born in the wrong era.

Confirmed! These are Mexican fishermen using "low level" language :-) not clear what they're talking about but they mention distances in miles, not kilometres, as used at sea and/or USA.

Well, it's hard to invent something new nowadays lol… We are definitely all inter-connected via our brainwaves… I'sure they will find out a way to tap into those in a near future. Then they'll install repeaters everywhere so we can communicate just by thinking about what we want to say… Too much technology nowadays (or maybe I'm just getting too old).
Thanks Al for that new resource!

So much in common! Will get back to you later on this, busy day!

The up to date members list is always available via the menu or directly at www.30cw.net/cs though the list needs to be manually updated, I do it as often as I can.

See how great minds think alike?! There actually exists such a code for this idea, instead of calling CQ, just QTT <== click for more info!

Yes unfortunately Wikidot is having many issues of late. For this the solution is actually more simple: when you see the "Please wait…" just close that window, and refresh the main window of 30cw.wikidot.com or 30cw.net and you'll find that you are logged in. For some reason the "please wait…" page doesn't go away by itself and doesn't refresh the underlying page, in some browsers, not all. What browser are you using, for our debugging purposes it may help to know: it seems Safari you have to do this trick, but Chrome seems to be OK at least on the 30cw.wikidot.com URL.

If using the image insert tags via the wizard you'd also need a direct link and not from a site such as imgur which won't allow direct linking via non-HTML page so in this case as per your post above just put the URL without any tags around it.

When using a URL directly, no need to surround it with any tags. For images to be displayed, pleas click on the image wizzard in the tool bar above the text entry box, near the end of the first line, before the < / > symbol, the two greenish coloured ones, the second is "insert image wizard"

Re: Nice propagation today! by G4OJWG4OJW, 31 May 2021 03:37

On balance of probability, 30m SSB, unless from VK-LIDS, is pirates including fishermen, etc. I've sent the recordings to a Spanish speaking friend for his comments. Also usually SSB on primary services would be on a round .0 or .5 kHz — usually but not always.
