Hunting For NDBs In CLE246
ZSJ - 258 kHz Sandy Lake, ON : source |
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be split: 240.0 - 259.9 kHz and 420.0 - 439.9 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.
If you've been meaning to participate in CLE, then maybe this weekend is a fine time to try! Lately, we've had a lot of first time submissions so you won't be alone!
As well, if you're trying to learn CW, copying NDBs is perfect practice as the identifier speed is generally slow and the letters are repeated again every few seconds!
A nice challenge in this one is to hear ZSJ - 258 kHz. 'ZSJ' is located at Sandy Lake, in northwest Ontario.
'ZSJ' runs 500W into a 150' vertical and is well-heard throughout North America. It has been reported in Hawaii and in Europe. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 258.404 kHz.
At this time of the season, summer lightning storms may provide additional listening challenges but maybe we will get lucky. Propagation can often be as good as mid-winter if the lightning cooperates.
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, comes the details:
Hello all,
These are the final details for our 246th co-ordinated listening event
this weekend. We'll be listening in two contrasting frequency ranges.
First timer logs too? Yes, please!
Days: Friday 26 July to Monday 29 July
Times: Start and end at midday, your LOCAL TIME
Range: 240.0 - 259.9 kHz plus 420.0 - 439.9 kHz
(BOTH ranges are for ALL listeners)
Please log NDBs that you can positively identify in the ranges, plus
any UNIDs that you come across there.
The lower frequency range will be really hard for most listeners in
Europe, the higher range not at all easy for most others.
Send your final CLE log to [email protected] if possible as a plain text
email and not in an attachment.
Show CLE246 and FINAL at the start of its title to help us find your log.
Show on EVERY LINE of your log:
# The Date (e.g. 2019-07-26, etc.) or day (e.g. 26)
# UTC (the day changes at 00:00 UTC).
# kHz - the beacon's nominal published frequency (if you know it).
# The Call Ident.
Please show those main items first on each line, BEFORE any optional
details (Location, Offsets, Cycle time, Distance, etc.)
If you send interim logs, do make sure that you also send a 'FINAL' log
containing all your loggings. As always, do make your log useful and
interesting to everyone by including your own location and brief details
of the receiver, aerial(s) and any recording equipment that you used.
We will send the usual 'Any More Logs?' email at about 19:00 UTC on
Tuesday so that you can check that your Final 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 31 July. Joachim and I hope to complete
making the combined results within a day or two.
To help you with your search you can find lists and maps showing the
target NDBs for your part of the World at http://www.ndblist.info/cle.htm
Select the CLE SEEKLIST link there.
Good listening

Hunting For NDBs In CLE243
YPM - 274 courtesy: VE3GOP |
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 270.0 - 319.9 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.
If you've been meaning to participate in CLE, then maybe this weekend is a fine time to try!
A nice challenge in this one is to hear YPM - 274, located in northwest Ontario near Pikangikum.
'YPM' runs just 25W into a 100' vertical but is well-heard throughout North America. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 274.368 kHz.
Summer lightning storms may provide additional listening challenges but maybe we will get lucky.
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.

From CLE organizer Brian Keyte, G3SIA, comes the details:
Hello all
Our 243rd co-ordinated listening event is this weekend, covering a 50 kHz
frequency range - about three times wider than usual.
Days: Friday 26 April - Monday 29 April
Times: Start and end at midday, your LOCAL time
Range: 270.0 - 319.9 kHz (NDB signals only)
In part of the frequency range it might be quite a challenge to tease out
the NDB signals from among the DGPS ones.
Any first-time CLE logs will be very welcome, as always.
Please log the normal NDBs you can identify that are listed in the range
(it includes 270 kHz but not 320 kHz).
Please send your CLE log to NDB List, if possible as a plain text email
and not in an attachment, with 'CLE243 FINAL' at the start of its title.
Show on EVERY line of your log:
# The Date e.g. '2019-04-26', etc. (or just '26')
# UTC (the day changes at 00:00 UTC).
# kHz - the beacon's nominal published frequency if you know it.
# The Call Ident.
Those main items can be in any order within themselves, but BEFORE any
other optional details (Location, Distance, etc.) later in the same line.
As always, give details in your log of your own location and the receiver,
aerial(s), etc. that you were using.
If you send any interim logs, be sure to send a FINAL (complete) one.
You can find anything else to help you, including CLE seeklists for your
part of the World, from the CLE page, http://www.ndblist.info/cle.htm
Please look out for our 'Any More Logs?' email at about 17:00 UTC on
Tuesday so that you can check that your CLE log has been found OK.
Do make sure that your log has arrived at the very latest by 08:00 UTC
next Wednesday, 1st May.
We are hoping to make all the combined results within a day or two.
Enjoy your listening

An Old Friend Returns + A Heads-Up For CLE243!
Over the years, one of the ‘most heard’ NDB signals from Alaska was the decades-old beacon located near the western tip of the Aleutian Islands at Adak.
'ADK' had been around in one form or another since WWII but it suddenly vanished from the air in 2012. Like numerous other NDBs in Alaska, as well as in the lower 48 and Canada, once officially NOTAM’d (Notice To Airmen) as shut down for ‘maintenance’, they often never return.
Such was the case assumed by all NDB DXers with regard to ADK, especially following the cryptic 2015 NOTAM announcing a permanent closure. It was hard to believe that this early-morning regular was now gone for good.
Transmitting on the lower edge of the AM broadcast band (530kHz), ADK was often stumbled upon by wayward BCB DXers or sought-out as a good propagation indicator for the pre-sunrise Asia-North America path on the BCB. I’m sure that some even heard it on their analog car radios back in the day when many of them would tune down as low as 520kHz!
All that changed this weekend when Dan, VE7DES, a regular weekend-contributor to the RNA database, found ADK had risen from the dead after all these years and was putting a nice signal into the southern west coast of Canada!
It seems that ADK’s antenna had been blown down in the summer of 2012 which explains its sudden demise. An FCC employee in Alaska has indicated to me that in recent months there had been much interest in reviving ADK which would apparently allow more airlines access to the field than had previously been the case ... whatever the reason, NDB DXers are delighted to hear their long-lost friend once again!
Hopefully it stays around for many more years yet, but just in case, why not give a pre-dawn listen for its CW identifier on 531.034kHz, with your receiver in the CW mode. Long haul propagation can often be excellent in this part of the spectrum in the early morning and ADK has been logged from Hawaii to Illinois.
Here’s how ADK's 25 watts sounded here this morning at around 0530 local time.
Heads up for CLE243 this coming weekend ... final details coming mid-week:
For our 243rd Co-ordinated Listening Event, coming in a few days, we can expect a bit of a challenge.
Days: Friday 26 April - Monday 29 April
Times: Start and end at midday, your LOCAL time
Range: 270.0 - 319.9 kHz
Yes, it does include most of the DGPS beacons - and 50 kHz wide is about three times more than usual, but we shall only be listening for the 'NORMAL' NDBs.
We last searched for NDBs on these frequencies in February 2018 when a record 59 of us took part in CLE229.
We shall all have at least one end of the range for some easy listening, but the main challenge will be to find the Morse signals among those DGPS noises.
REU and RNA show that, in the last 18 months, about 310 and 200 normal NDBs have been heard in this range by listeners in Europe and North America respectively.
REU and RNA show that, in the last 18 months, about 310 and 200 normal NDBs have been heard in this range by listeners in Europe and North America respectively.
There are also several to be heard by members away from Europe and North America, as you can see in the map from RWW, below.
Please look out for the 'Final Details', which as usual will follow about two days before the start.
Happy Easter!

Hunting For NDBs In CLE242
Online KiwiSDR Network |
CLE242 runs this weekend and is a bit different than most. This time, listeners are required to use an online remote receiver to do their beacon-hunting.
There are many parts of the world where beacons have yet to be recorded to the database and this will be a great opportunity to find and report them.
Over the past few years, the number of online SDRs has grown immensely, as has their ease of use. Although there are several online systems, my favorite is the KiwiSDR network, where one can normally find over 400 receivers available at any time. As well, every one of them has the same familiar intuitive interface ... figuring out how to tune them and make them behave the way you want only takes a few moments.
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 1020Hz 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 242nd listening event starts this Friday. The last time everyone
listened via remote receivers was 40 CLEs and over 3 years ago. Since
then the receivers have improved enormously – easier to use, better
design and a much greater choice of sites Worldwide for you to use.
If you don’t like the idea of remote listening we urge you to at least
please give it a try. I predict that several of us who ‘have a go’ in this
CLE will be very pleased to discover a fascinating new world of NDBs.
You only need a modest PC and a slow internet connection - and the
ability to read slow Morse! (Even a tablet is sufficient, though a bit
difficult to use without a mouse)
Days: Friday 22 March - Monday 25 March
Times: Midday on Friday to Midday on Monday, local time AT THE REMOTE RX
QRG: Normal LF/MF frequencies (190 - 1740 kHz)
NDBs: A MAXIMUM of 100 normal NDBs (not DGPS, Navtex, Amateur)
(that’s not intended to be a target to reach!)
Choose any ONE receiver, remote from you, for all your CLE listening.
Remember that reception conditions will depend on the local time of
day/night at the receiver (no through-the-night listening for us this time?)
The ‘biggest and best’ of the remote receivers is probably still the SDR
at the University of Twente at Enschede in the east of Holland.
Several hundred listeners use it, all at the same time and all unaware
of each other. Its PA0RDT mini-whip aerial high above the metal roof
of the building allows it to receive well on the NDB range of frequencies.
Just enter http://websdr.ewi.utwente.nl:8901/ into your browser.
In seconds you should see details of the receiver and advice on how to
use it.
If you want to choose a different location, or an easier-to-use receiver
with fewer facilities, the Kiwi receivers are also SDRs. They are mostly
in radio enthusiasts homes and they usually only support a handful of
simultaneous users.
Go to https://sdr.hu
To display the Worldwide map use the button on the right side of the screen
- experiment with (multiple) use of the + and – buttons.
Some sites of any kind have aerials that are quite unsuitable for NDB
listening, but others are excellent. Some of our members have been busy
recently researching them and their suggested ‘best ones’ are listed below.
For each receiver, whatever its kind, do read the helpful advice carefully
before using it. There is no charge and you don’t register or 'log in', but
you may be invited to type your chosen identification in a 'Name’ or
‘Callsign' box. There may be a time limit for each user (e.g. 2 hours in
any 24 hours) and ‘late comers’ may temporarily have reduced facilities.
Seeklists? The REU/RNA/RWW Website can help a lot if you enter the
Locator of your chosen receiver in the From GSQ box there.
To avoid getting details of thousands of NDBs, initially set the DX limit
to something small and/or enter one or two nearby states or countries.
LOGS (Please read CAREFULLY):
Please show the LOCATION details and the TYPE OF REMOTE RECEIVER
clearly (and your own location to help us identify you).
Include on EVERY LINE of your log:
# the UTC date - e.g. ‘2019-03-22' (or just '22')
and UTC time (the day changes at 00:00 UTC).
# kHz - the nominal, published, frequency.
# Call Ident.
Show those main log items FIRST. Any other, optional, details such as
the NDB's location, etc., must go LATER on the same line.
You could include any UNIDs - e.g. separately if you already have 100
identified loggings.
As this is a special CLE, any extra comments in your log on your listening
experience (whether good or not!) will certainly be of interest.
Please post your log to NDB List, preferably as a Plain Text email
(not in an attachment) using 'CLE242' and ‘FINAL’ in its title. We will
send the usual 'Any More Logs?' email at about 21:00 UTC on Tuesday
so you can check that your log has been found OK.
(NB: that is 3 hours later than usual)
Do make sure your log has arrived on the List by 09:00 UTC on Wednesday
27 March at the very latest. Joachim and I hope to finish making the main
combined results later on that day or soon after.
REMINDERS:
Only ONE remote receiver of your choice.
Not more than 100 loggings
Start and End at midday at the receiver.
Enjoy!

To help you with your choice of a remote receiver, below are recommendations
and/or advice provided by from some of our members:
The stations in yellow are among the ones that disable the waterfall when there are more than two users -
they can still be used and are still excellent stations.
Advice about their own and other Kiwis have been given in emails to NDB List,
mostly in the last few days:
Roelof B: His KiwiSDR is making all four channels available for the CLE
Tony C: Has added his openwebrx NDB receiver to SDRHU. 3 or 4 users
Bill S: Email to NDB List on 4 Feb (A list of USA and CAN SDR's that may
be useful, compiled by Dave AB5S and posted on the Boatanchor List)
Joe N5PYK: The West Texas KiwiSDR welcomes CLE participants.
We are grateful to all the above.
Any further advice about suitable remotes will be welcome.
Do you fancy using something really basic for the CLE? The Global Tuners
still exist – we used 6 of them successfully in CLE202. There are usually
about 50 of them on-line and many are older traditional receivers that
support only one user and are seldom suitable for the NDB frequencies.
But there might still be a gem or two among them:

Hunting For NDBs In CLE241
ZWW - 215 courtesy: VE3GOP |
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:
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!
- 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

Hunting For NDBs In CLE240
OO-391kHz - Oshawa, Ontario courtesy: VE3GOP |
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 385.0 - 399.9 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.
A wonderful challenge for listeners in North America is to hear little OO - 391kHz, located in Oshawa, Ontario. It puts out only 7 1/2 watts but has been logged on both coasts as well as in Europe! Listen for its USB CW identifier (with your receiver in the CW mode) on 391.396 and its LSB ID on 390.595 kHz.
MF propagation this past week has been good and signals in this frequency range should be propagating well if things stay undisturbed for the weekend. As usual however, a large coronal hole has returned to its monthly CLE position and its weekend effects are still unknown.
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 1020Hz 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 240th Coordinated Listening Event is less than a week away.
We can now forget all about pyramids and relax with a straightforward
event. Whether you are a keen propagation watcher or just a
take-what-comes listener, please join in.
Days: Friday 25 January - Monday 28 January
Times: Start and end at midday, your LOCAL TIME
Range: 385.0 - 399.9 kHz
Please log all the NDBs you can identify that are listed in that range
(it includes 385 kHz but not 400 kHz) plus any UNIDs you find there.
We last used this frequency range for CLE224 in October 2017.
Please send your final log to the List (no attachments and ideally
in a plain text email) with ‘FINAL CLE240’ in its title.
Show on each line:
# The Date (e.g. '2019-01-26' etc. or just '26' )
# 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 18:00 UTC
on Tuesday so that you can check that your log has been found OK.
The combined results should then be completed within a day or two.
You can soon find full details about current and past CLEs from the CLE page
http://www.ndblist.info/cle.htm It includes access to CLE240 seeklists
for your part of the World, prepared from the previous loggings in Rxx.
Good listening - enjoy the CLE.

(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)

CLE237 Results
Last weekend's CLE237 was truly a workout. Not only was the format challenging, hunting for different grid square fields, but propagation was superb ... a vast departure from the normal CLE propagation-curse!
This combination resulted in many daytime hours spent reviewing three nights of Perseus recordings, the downside of being able to sleep all night rather than staying up until 0300 while listening live!
All told, 118 NDBs in 41 different grid fields were logged. Of these 118 stations, 12 were 'new catches'. After DXing NDBs since 1985, new catches are getting harder and harder to find but last week's great conditions were the best heard here in several years.
Today's quiet Sun! |
With a very quiet Sun for a couple of weeks now, these great MF conditions are what many have been waiting for since the last solar low many years ago ... propagation below the broadcast band can be truly remarkable when these quiet conditions continue for many weeks at a time.
Here are a few interesting CLE catches as recorded on the Perseus SDR.
NDBs QY (Sydney, Nova Scotia), YBB (Pelly Bay, Nunavut)and 3Z (Russell, Manitoba) all sharing 263kHz within a few Hz of each other.
My full CLE237 log is shown below. As usual, a Perseus SDR and an 'inverted-L' (resonated to 300kHz) was used for the activity.
