Hunting For NDBs In CLE241

ZWW - 215 courtesy: VE3GOP
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 190.0 - 239.9 kHz as well as any NDBs with carriers on 'half-way' frequencies ‘nnn.5 kHz’, from 190.5 - 999.5 kHz)

For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

Never tried the CLE? If you've ever been wondering what can be heard 'below' the broadcast band, this weekend would be a great time to give a listen and enter your first CLE!

A nice challenge in this one is to hear 'ZWW' on 215 kHz located near Winnipeg, Manitoba. It's a 25-watter and is well-heard throughout North America. Listen for its CW identifier on 215.388 kHz (repeated every 10 seconds), with your receiver in the CW mode .

MF propagation this week has been good and signals in this frequency range should be propagating well if things stay undisturbed for the weekend.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' near Fargo, ND, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, come details via the The NDB List Group:

Hello all,

Our 241st Co-ordinated Listening Event is next weekend. 

Do join in if you can.   First-time CLE logs will also be very welcome.

   Days:   Fri. 22 Feb. - Mon. 25 Feb.,  Midday-Midday, your local time
   Frequencies:    NDBs from 190 - 239.9 kHz
   PLUS:   Normal NDBs with carriers on 'half-way' frequencies ‘nnn.5 kHz’
                                  (from 190.5 - 999.5 kHz)

Both halves are for everyone to try.

Away from Europe many of the frequencies below 240 kHz are busy with
NDBs.  In Europe there are very few, but some DX ones might be heard
from North America and maybe from a few other places.

The normal NDBs which have carriers on the 'half-way' frequencies
e.g. 267.5 OPW,  333.5 VOG,  370.5 LB, 390.5 ITR, 433.5 HEN (not DGPS)
are scattered across Europe but there are very few of them elsewhere.
'Hot spots' are ENG and ITA.

These half-frequencies usually give comfortable QRM-free listening
and probably some good catches as a result.

America has only one or two (e.g. 381.5 SJX in MI) but East and West
coasters might hear some DX ones.

We last used these 'rules' for CLE225 in November 2017.
Please look out for the Final Details about two days before the CLE.

These listening events serve several purposes. They:
  • determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
  • determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
  • will indicate the state of propagation conditions at the various participant locations
  • will give you an indication of how well your LF/MF receiving system is working
  • give participants a fun yet challenging activity to keep their listening skills honed

The NDB List Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

You need not be an NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

Remember - 'First-time' logs are always VERY welcome!

Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.

Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Have fun and good hunting!

ARRL DX CW 2019 in the books

The setup
Well the ARRL DX CW has come and gone for 2019 and my effort was one of interest only. I knew I had non radio related things to do this weekend and we were out each evening. Actually the contest caught me by surprise as I usually plan ahead and make time. This week I was checking WA7BNM contest site and was shocked to see the contest was this weekend! This was the first real contest run for my new IC7610 rig. Now I am used to the Elecraft K3 but honestly the 7610 preformed for me just as good as my K3 did. I left the filter set at 250Hz and never had any issues when Kilo watt  contesters were side by side belting out their call. The waterfall  on the 7610 was par with my old Elecraft P3 also it was an added bonus that N1MM+ has a spectrum scope fed directly from the 7610. Having the two independent receivers was nice. When I found rare DX but there was a pileup I left one receiver there and checked in now and then. With the other receiver I would continue the search and pounce. I had been away from the 7610 for about 2 weeks regarding CW operating so I at times found I was slow to figure out how some functions were done.
As for the contest I was running 60 watts (not sure of reason for the 60 watt number) and my antenna is the MFJ 1788 mag loop. I am in a condo so it’s a balcony antenna about 180 feet up facing south east. The software was N1MM+ and MRP40 CW decoder for the super fast fisted contesters. On Sunday the winds for some reason really picked up and my MFJ loop was moving around the balcony. I shut the radio down and took it in I would rather save the antenna from damage than taking a chance on getting more contacts.
I made only 25 contact and a score of 1575 BUT my intention was not to blow the doors off  with a great score. Instead after I made contact with a station I would look them up on QRZ.COM and read about either the individual or the contest station. Over all the limited time I was in the contest I had a blast and was very please with the Icom 7610 and the ability of my balcony mounted Mag loop antenna.

A screen shot of the ARRL DX CW contest
I was on for a short time yesterday afternoon but we had a dinner date to go to in the evening so things were cut short. I stayed on 20m as it seemed to be producing very surprising results including a contact into Japan. I was shocked when I heard his call just come from out of no where! I gave him a call and he came right back to me and in about 5 minutes after he was spotted along with some other JA's the pileup was huge. It was just luck I was where I was at the time and made the contact with 60 watts and my MFJ 1788 loop.
I will see if the propagation gods are smiling down on me today as I give the contest another go this afternoon.

SOTA News: Joyce/K0JJW Is Half a Goat

Recently, my SOTA Activating Partner and Spousal Unit Joyce/K0JJW racked up more than 500 activating points for Summits On The Air (SOTA). This is halfway towards the coveted Mountain Goat award, so naturally this is referred to as Half Mountain Goat. Steve/WG0AT noticed this achievement and created this certificate for her.

She has activated 108 summits in 13 different associations (including HB Switzerland). All radio contacts have been on the VHF/UHF bands. She really likes it when another woman gets on the air with her, which she calls F2F (Female-to-Female) radio contact.

Congratulations, Joyce!
