    Hunting For NDBs in CLE282

    YLD-335 Chapleau, ON (ve3gop.com)
    It's CLE time once again. This is a challenge for all newcomers to NDB listening and the ultimate test of your medium frequency receiving capabilities. Can you meet the challenge?'CLE's are 'Co-ordinated
    Listening Events, and NDB DXers around the world focus their listening time
    on one small slice of the NDB spectrum. It's back to a normal activity
    with a frequency span of 335.0 - 349.9 kHz.
    A good target for all NA listeners is YLD on 335 kHz in Ontario. Listen for
    its upper sideband CW identifier on 335.405 kHz. I believe it is slated for decommissioning shortly ... hopefully I'm not too late for this one.
    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: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 22 July - Monday 25 July 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 positively identify 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
    and very long logs are welcome (in-between ones are good too!)

    Send your CLE log to the List, preferably as a plain text email (not in an attachment) with ‘CLE282 FINAL’ in its subject line.

    Please show on EVERY LINE of your log:
    # The date (e.g. '2022-07-23' or just the day no. '23') and UTC
    (the day changes at 00:00 UTC).
    # kHz (The beacon's nominal published frequency) If you don’t know it, please visit: https://rxx.classaxe.com where you will find all the details. # 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 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 27 July. We 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
    It includes a link to seeklists for the Event from the Rxx Database.

    Good listening Brian and Joachim (CLE Coordinators)-------------------------------------------------------------------From:
    Brian Keyte G3SIA ndbcle'at'gmail.comLocation: Surrey, SE
    England (CLE coordinator)------------------------------------------------------------------- (Reminder: If you wish you can use a remote receiver for your loggings, stating its location and owner - with their permission if required.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 actually in service and on-the-air so the newly-re-vamped Rxx 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

    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!
