Hunting For NDBs In CLE267
21 April 2021 | by  | |
| YUT - Replulse Bay, NU (courtesy: ve3gop.com) |
Propagation on MF has been both hot and cold for the past few weeks, seemingly depending on where you live and the amount of geomagnetic activity affecting your region. As well, the Sun has been throwing a lot of Coronal Hole Streams toward earth which may or may not affect this weekend's propagation ... but this is all part of the radio-magic fun.
A 'challenge target' for listeners in North America is YUT - 335kHz in Repulse Bay, NU, at the north end of Hudson Bay. Even though running just 25 watts, it's widely heard throughout North America and Europe and is a good target for listeners everywhere. Listen for YUT's upper sideband on 335.406 kHz.
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. These databases have recently been re-vamped and are slicker than ever before!
From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:
Hello all
Here are the full details for this weekend's co-ordinated listening event.
It is open to everyone including CLE new-comers:
Days: Friday 23 April - Monday 26 April
Times: Start and end at midday, your LOCAL time
Range: 335.0 - 349.9 kHz
Wherever you are, please join us and log the NDBs that you can positivelyidentify that are listed in this busy frequency range (it includes 335.0 kHz but not 350 kHz) plus any UNIDs that you come across there.
Very short logs and very long ones are welcome (in-between ones are OK too!)
Send your CLE log to the List, preferably as a plain text email (not in an attachment) with ‘CLE267 FINAL’ in its subject line.
Please show on EVERY LINE of your log:
# The date (e.g. '2021-04-23' or just the day no. '23') and UTC (the day changes at 00:00 UTC).
# kHz (the beacon's nominal published frequency, if you know it)
# The Call Ident.
Show those main items FIRST on each line, before other optional details such as Location, Distance, etc. If you send any interim logs to the List during the event, please also send your 'FINAL', complete one.
Always make your log interesting to everyone by giving details of the listening location and brief details of the receiver, aerial(s), etc.,that you were using.
We will send the usual 'Any More Logs?' email at about 19:00 UTC on Tuesday so that you can check that your log has been found OK.
Do make sure that your log has arrived on the List at the very latest by 08:00 UTC on Wednesday 28 April. Joachim and I will then hope to complete making the combined results within a day or two.
You can check on all CLE-related information from the CLE Page
http://www.ndblist.info/cle.htm
It includes a link to seeklists for the Event from the Rxx Database.
Good listening

(REMINDER: You could use any one remote receiver for your loggings,
stating the location and owner - with their permission if required.
A remote listener may NOT also use another receiver, whether local
or remote, to make further loggings for the same CLE).
If you are interested in some remote listening - maybe due to local difficulties - you could use any one remote receiver for your loggings, stating its location and with the owner's permission if required.( e.g. see kiwisdr.com ) A remote listener may NOT also use another receiver, local or remote, to make more loggings for the same CLE.
These listening events serve several purposes. They
• 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
Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event.
The NDB List Group is a great place to learn more about the 'Art of NDB DXing' or to meet other DXers 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!

10-10-10 Event-Happy B-day WØC-SOTA
WG0AT/Steve
May 1st, 2010 – WGØAT/Steve sent a CQ from Mount Herman in Colorado and thus inaugurated the birth of Summits On The Air (SOTA) in WØ land with 33 CW contacts around the world.
Fast forward to today, Steve is still sending CQs from Mount Herman (WØC/FR-Ø63), and other peaks, almost on a daily basis but he also inspired countless hams (incl. yours truly) to join a growing bunch of people who love the outdoors and combine their hiking activities with their radio hobby.
Some statistics… during the last 10+ years the Colorado Association (WØC) grew from:
- 219 initial (seed) summits to a total of 1797 qualifying summits
- a handful of Activators to ~180
- a few chasers to almost 200
These highly motivated men and women of all ages activated more than 7,400 summits, generated more than 40,000 points and 15 Mountain Goats (MG) – many of them double or even six-fold (thanks KXØR/George).
WØC Chasers worked over 90,000 stations around the world, generated almost 500,000 points and 33 Shack-Sloths.
To celebrate our 10th Anniversary1, WØC-SOTA is organizing a 10-10-10 Event2 with a challenge for Activators and Chasers alike.
Activator challenge: Activate 10 (or more) 10K (or higher) summits (in WØC) within 10 days.
Chaser challenge: Chase Activators on 10 different (or more) qualifying WØC summits (10K or higher) within the 10 days.
Event Date: We will kick-off the event in conjunction with the Colorado 14er event on August 7th, 2021 and conclude on August 16th.
Everybody is invited to participate. Plan your vacations and business-trips to Colorado accordingly. Block off these days in your calendar. Get in shape… repair your antennas and radios. It’s a once in a decade event 😉
There will be a ranking of all participants who meet the challenge. Photographer and new SOTA enthusiast Dan Oldfield (NØOLD) is generously donating a personalized and autographed print from his Colorful Colorado collection to each of the top 3 in both challenges.
More details will be announced as soon as they are hashed out on the WØC-SOTA Website (you can subscribe to get the latest updates) and the NA-SOTA group.
For the org. team
KØMOS/Matt
1 It’s actually the 11th Anniversary but the COVID-19 Pandemic and historic Wildfires in Colorado interfered in 2020.
2 All SOTA rules apply
