30m CW

Join us in keeping CW alive and well on the 30m band

Pусский - Français - 日本語 - Deutsch - Nederlands - Español - Italiano - Português - Svenska

The 30m CW interest group encourages CW activity on 30m to ensure that we do not lose this very special prime CW band to other modes, nor lose it 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 all CW operators who use or wish to use the 30m radio amateur band using Morse Code for "non-5NN" activities and who support the aims specified below:

  • Giving honest signal reports (RST)
  • Avoiding unnecessary split operation
  • Promoting human CW QSO on 30m
  • Encouraging friendships among CW OPs

Please use the forums as often as you can for friendly exchange of information about 30m activities, nets, news, propagation, antennas and sharing of personal experiences and nice QSO on 30m as well as anything else related to 30m of interest to 30m CW operators.

If you agree with the above aims, please join this site via the button below:

Thanks to OM Fabian DJ1YFK 30CW31 you can now see 30CW members on air. If you want to narrow down to only 30CW members, first tick the none box then 30CW for the clubs, and you can also filter to 30m by ticking first none, then 30m.

30CW Newsletter by VK5EEEVK5EEE, 15 May 2021 06:30

Nets page updated. Any other nets on 30m please let us know.


77 de Lou, VK5EEE

Just looked at all the links, thank you! Am also thinking of the QRP guys 3 band EFHW etc. May take a while to get back on air but worth dreaming about meantime!


77 de Lou, VK5EEE

This is excellent news Matt. Very encouraging. Am also thinking of experimenting with a quad loop or delta loop. My first experiment years ago with one didn't work out, I didn't have enough space. Keep us informed about any DX you manage with it and its general performance, would be very interesting to know. Also noise levels, hopefully it's quiet?

Re: 10Mhz Delta Loop by VK5EEEVK5EEE, 09 May 2021 15:28

GOOD TO HEAR FROM YOU PETER OM. GLAD YOU ARE STILL ACTIVE ON 30M. ARE YOU GETTING ANY QSO ON THE BAND? ON MONDAY EVENINGS THERE IS THE AA-CW NET YOU CAN TRY TO CALL IN WITH JL1MUT AROUND 1210UTC I THINK THAT IS ABOUT 8.10PM YOUR TIME SOMEWHERE AROUND 10146-10149 TOP END OF THE BAND.

Here’s some additional info from the 10 MHz Delta Loop series (across the 1 year it was on the air from Grid Square FM19). Thanks to all of you for your QTT QSO’s:

Photo of Delta Loop “Config A1” “squashed” provided excellent match and solid single-hop reports out to 1,000 NM.

Photo of Delta Loop “Config E1” “equilateral” fed at top corner with 300-ohm twin lead, slightly farther reach to the West.

I found the following charts helpful in building these antennas:

At our new 3rd floor apartment QTH we are presently running a 10 MHz Vertical against four ground radials. Radials are tuned with the MFJ-931 Artificial Ground:

Receive antenna is a Chameleon RXL:

We also on occasion run this stealth 10 MHz EFHW as a transmit antenna across the roof of the apartment building:

We also enjoy operating 10 MHz Portable QRP with a QRP Guys Tri-Band Vertical:

Looking forward to reporting back with the radiation pattern plots compiled from another 1-year’s worth of 10 MHz QSO’s from these transmit antennas.

Cannibalized the G5RV turning it into a delta loop for 10.125 MHz. Rather than pouring an RF cup of tea on 80-10m, I’d rather be a shot of whiskey on 30m ;)

The new 30m delta loop fits nicely in the same location as the G5RV with the feed point at 6 ft. AGL, putting the top of it around 35 ft. AGL. The antenna is oriented to provide peak lobes E-W, although the house is pretty much blocking it to the west, and this configuration is modeled as having a 45 degree take off angle.

When matched with a 1:1 balun, the impedance at the feed point is 100 ohms with an SWR of 3.2. After trimming to resonance and matched with a 4:1 balun, impedance at the feed point drops to 30 ohms with an SWR of 1.6 and a capacitive reactance of 0.

Next I “squashed” the delta loop: lengthening the top (relative to the sides) and this raised the impedance, providing a better match for the 4:1 balun AND getting more of the antenna higher up in the air (see below). We’ll call this “Configuration A1” for a future test which is ideal for a setup in the backyard.

Finally the delta loop matched up at an SWR of 1.0, impedance at the feed point of 44 ohms, and a capacitive reactance of zero. Connecting it to the radio, I picked up Poland and Greece, which is the first ever DX I’ve received on 30m. The antenna handles 100 Watts and the SWR needle doesn’t move.

Hello all, well still plodding on trying to teach this "old dogs new tricks" and learning cw "again".
Just looking back through this years 30m log
Currently showing VK,8P,PJ4,EA8,ZF,HK,SV9,DL,OH,FY,HA,HB0,LY,TZ,SP,EA,SM,5H.
Running here a simple in vert L (vertical part 35 foot), and 100w so there is dx about.

17.00hrs gmt on wards seem good for me in G

Regards to all

Hope we all safe in this current situation we find our self in,
As well as plenty of small jobs getting done during "lock down", been grabbing a few Q's on 30m (along with other bands)
Running 100w into inverted L, The evenings been getting occasional VK working Caribbean with some good signals.
Getting back into me cw again, stay safe and regards to all

there does seem to be some interest in the sCWs principle:
- apparently it's centered at about 15wps, for those who like to Chat ?.
but - where is it on the 30m band ?. it could be around 10.115 ?

anyway - do place some TX out there & see what happens.

Evening 12 NOV 30m QSOs near 10112 kHz: local static QRN again quite heavy, and very few signals on band. DDK9 weak, also WWVH on 10000 kHz weak and lots of QSB, propagation show conditions as fair. Only 2 QSOs, many thanks to: IT9DQT and IK7XJA (30CW152) Franco, latest member to 30CW!

Re: 30m CW QSO Party by VK5EEEVK5EEE, 12 Dec 2018 16:29

11NOV 30m QSO TNX: 3W3B (Vietnam), DK6HN, DL8FBH, EA4EPY, HB9AUK, IK7XJA, RX4CD, RX6B, S57V, UR4EZ, VK6RR (30CW2), VK7AD. Many of the European QSO were with modest power (100W) and modest antennas (dipoles). Most QSO 1530-1630Z on 10111.1kHz. Hope CU TMW, look for me around 10112.

Re: 30m CW QSO Party by VK5EEEVK5EEE, 11 Dec 2018 16:47

Evening of 10 December: All Asia CW Net (see nets) with HS0ZEA and JL1MUT (30CW12) on 10149 kHz, then a nice time with many more QSO on 30m: LY5A, OU5U, DL5CL, DL4ZM, F5TFW. Including modest barefoot stations with similar set up to mine still RST 559. And HA8VK on 20m as lone signal here on the CW band.

Re: 30m CW QSO Party by VK5EEEVK5EEE, 10 Dec 2018 18:10

My report for 9 December: I called CQ for hours though the band was open (30m is open 24 hours a day) although conditions were on the poor side, finally had a weak RST 339 calling me: it was OM Dave VK4YD, we then had a nice QRS QSZ QSO. (QSZ: repeating each word twice).

Today 10th December at time of writing, I put on my auto-CQ beacon (not used it in over a year, got it working without too much headache, twisting wires together) calling CQ on 10110 and called OM Tim VK3IM to ask if he could hear me, as coincidence would have it he was just about to answer my CQ, having come across my signal. Had a long rag chew, and now back to auto CQ while relaxing in the living room until any answers.

If you have any problem to post in the forum or get a "permission denied" please send a message to VK5EEE asking for help and giving details of your problem. Thank you.

Re: Welcome to 30cw.net forums by VK5EEEVK5EEE, 09 Dec 2018 07:28

Dear Friends,

a new initiative. Not a contest, but a QSO party. Call CQ any day, especially on the +30 minutes half hour, and around X kHz above band edge where X is the date.

So for example, today is the 9th December, so 10109, the 31st will be 10131. Always check frequency is clear with QRL?

Please exchange your name, 30CW Nr and QTH on first over, and on the 2nd, your station details including power and antenna and even what Morse Key you are using.

End your QSO with "77" see the meaning here: 77

If you have a positive experience or suggestions or comments, please post them here in the forum or as a reply to this post.
