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, transmitted on 365 kHz and its upper sideband CW identifier was tuned at 366.025 kHz while its lower sideband CW ident could be tuned at 363.946 kHz. Its USB tone was actually 1025 Hz while its LSB tone was 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 organizers comes the following CLE info:
Our 285th Coordinated Listening Event starts on Friday.
This frequency range is not packed with signals for any of us, but if conditions are OK there could be some nice surprises.
Do join in, whether you have days to spare, or only an hour or so over the weekend.
Days: Friday 28 October - Monday 31 October 2022
Times: Start and end at midday your LOCAL time
PLEASE NOTE that most of us will be changing our house clocks
during the weekend, but UTC time continues without changes.
Range: 400 - 419.9 kHz
Please log all the NDBs that you can identify with nominal (listed) frequencies in the range - it includes 400 kHz, but not 420 kHz - plus any UNIDs that you come across there.
Send your final log to the List (no attachments please) with ‘CLE285’ and 'FINAL' in its title.
Show on each line:
# The Date (e.g. '2022-10-28', etc., or just '28' )
# The Time in UTC (the day changes at 00:00 UTC).
# kHz - the nominal published frequency, if known.
# The Call Ident.
Please show those main items FIRST. Other optional details such as Location and Distance go LATER in the same line.
As always, of course, tell us your own location and brief details of the equipment that you were using during the Event.
We will send the usual 'Any More Logs?' email at about 20:00 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 by 09:00 UTC on Wednesday 2 November at the very latest.
We hope to complete making the combined results within a day or two.
You can find full details about the coming CLE from the RWW Website, including the CLE285 seeklists for your part of the World – just select CLE from the main menu.
Details about current and past CLEs are available from Alan’s NDB List Website, http://www.ndblist.info
Good listening

(If you would like to listen remotely you could use any
one remote receiver for your loggings, stating its location
and owner and with their permission if required.
A remote listener may NOT also use another receiver,
local or remote, to make further loggings for the same CLE)
A remote listener may NOT also use another receiver, whether local or remote, to obtain further 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!
