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.
A 'challenge target' for listeners in North America is YZS - 362kHz
in Coral Harbour, NU, on Southampton Island at the north end of Hudson Bay. It's widely heard
throughout North America and Europe and is a good target for listeners everywhere. Listen for YZS's upper
sideband on 362.405 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
Our 266th Co-ordinated Listening Event is almost here.
Can
new 'listening eventers' join in too? YES, PLEASE!
Joachim and I are
always pleased to help first-time CLE logs
through the harvester
program.
Days: Friday 26 March - Monday 29 March
Times:
Start and End at midday, your LOCAL time
Range: 350.0 - 369.9
kHz
Please log all the NDBs you can identify that are listed in this
range (it includes 350 kHz but not 370) plus any UNIDs that you come across
there.
You can find full information to help you, including seeklists made
from
REU/RNA/RWW, by going to the CLE page http://www.ndblist.info/cle.htm
and clicking on CLE SEEKLIST there.
Please send your 'Final' CLE log
to the List, if possible as a plain text
email and not in an attachment and -
important - with 'CLE266' and 'FINAL'
in its title.
Please show the
following main items FIRST on EVERY line of your log:
# The full Date
(e.g. 2021-03-26) or just the day (e.g. 26)
and UTC (the day changes
at 00:00 UTC).
Many of us will be changing our house clocks
during
the weekend, but UTC CONTINUES UNCHANGED.
# kHz - the
beacon's nominal published frequency, if you know it.
# The Call
Ident.
Optional details such as Location and Distance go LATER in the
same line.
Please always include details of your own location and brief
details of the
receiver, aerial(s) and any other equipment you were
using.
Joachim or I will send the usual 'Any More Logs?' email at about
19:00 UTC
on Tuesday so you can check that your log has been found
OK.
Make sure that your log has arrived at the very latest by 08:00 UTC
on
Wednesday 31 March. We hope to make all the combined results within a
day
or so.
Good listening
Brian

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!
