Hunting For NDBs In CLE252
AP-378 Mayne Island, BC |
How time flies. Once again it's a CLE weekend. It seems like the last one was just a week ago!
'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.
This time the hunting ground is the 15 kHz slice from 370.0 - 384.9 kHz.
This is a somewhat dreaded range for me since my local blowtorch NDB, 'AP' (378 kHz), sits right in the middle of the range. 'AP' is located at the entrance to Active Pass, the main ferry route to Vancouver Island, and the antenna is about 3/4 of a mile down the beach from me. Needless to say, the beacon is about 40db over S9! With careful loop nulling, I can reduce this by about 25db but it's still an enormous signal to deal with.
Hopefully you can put 'AP' in your own log this weekend but its 25-watt signal will be much weaker for you. It's been logged as far east as Illinois and with your receiver in the CW mode, can be found on 378.399 kHz.
Things seem geomagnetically quiet at the moment but we are due for another blast on January 21st ... hopefully things settle-down for the weekend event.
From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:
Hello all
Here is your Early Advice of our next Co-ordinated Listening Event.
We are back to a normal event looking for the NDBs in a narrow and
fairly relaxing frequency range. Beginners, occasionals and regulars
are all very welcome to join in.
Days: Friday 24 January - Monday 27 January
Times: Start and end at midday, LOCAL TIME at the receiver
Frequencies: 370 - 384.9 kHz
Just log all NDBs you can identify that are listed in the range (it includes
370 kHz but not 385 kHz) plus any UNIDs that you come across there.
We last had a close look at this frequency range in CLE236 at the end of
September 2018.
Please look out for the full Final Details in a few days, including how to
present your log, etc.
Please send your CLE log to the List in a plain text email if possible(not in an attachment) with CLE252 and FINAL at the start of its title.
Show on each log line:
# The date (e.g. 2020-01-25, etc., or just 25) and UTC
(the date changes at 00:00 UTC)
# kHz (the nominal published frequency, if known)
# The Call Ident.
Show those main items FIRST - other optional details such as Location
and Distance go LATER in the same line.
If you send interim logs, please also send a 'FINAL' (complete) log.
As always, tell us your own location and brief details of the equipment
that you were using during the weekend.
To help you to plan your listening, seeklists and maps for your part of the
World are available via the CLE page http://www.ndblist.info/cle.htm
Good listening - enjoy the 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. A remote listener may NOT also use another receiver, local or remote, to make further loggings for the same CLE.
-------------------------------------------------------------------
- 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
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!
Hunting For NDB Pairs In CLE251
A fairly popular CLE event held around this time of the year is the "Noah's Ark" Holiday CLE!
It calls for listeners to hunt down and log pairs of NDBs from as many 'radio countries' as possible.
As explained below, in NA and Australia, states and provinces count as separate 'radio countries' thankfully.
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! We continue to have 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!
This past week has seen a long period of great propagation quickly get worse with the arrival of another coronal hole stream. This is quickly abating and the ionosphere may well have fully recovered for the nine-day event.
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
We hope you are looking forward to our "Noah's Ark" Holiday CLE – it
starts at midday on Christmas Day and you can listen at any times
from then right through to midday on Thursday 2nd January.
It's very straightforward. Just as the animals went into the Ark two by two,
so the Radio Countries' NDBs will go into our logs two by two.
Days: Wednesday 25th December to Thursday 2nd January
Times: Start and End at midday, your LOCAL TIME
Target: A maximum of TWO NDBs from each Radio Country
Range: 190-1740 kHz
So during the course of the event we shall try to log TWO NDBs from each
of as many Radio Countries as we can - e.g. 2 from France, 2 from Spain,
2 from the Florida, 2 from Quebec, 2 from Brazil, 2 from New Zealand, etc.
Each Australian and USA State and each Canadian Province is a separate
Country. For our full list see: www.ndblist.info/beacons/countrylist.pdf
Each NDB making the pairs can be logged at any times during the event.
UNIDs, Amateur, DGPS and Navtex beacons are not included, but any
UNIDs can be shown in a separate 'non-CLE' list or in a separate email.
Noah didn't have single animals in the Ark, but if you can only log ONE
NDB from a Country, it will still be welcome in your log without a mate!
Everyone is asked to please listen for YOUR OWN NEAREST active NDB
and include it with the one other logging for that Country (if any).
For details of a country’s active NDBs go to www.classaxe.com/dx/ndb/rww/
If you are listening from Europe or North America replace the rww by
reu or rna respectively. Next to 'Locations' enter the State or Country
abbreviation(s), then select 'Only Active’ at the bottom.
Post your final, complete log to the List (please not in an attachment)
with CLE251 and FINAL in the Subject heading, to arrive at the very latest
by 09:00 UTC on Saturday 4th January.
As usual, please include on every line of your log:
# Date** and UTC (the day changes at 00:00 UTC)
# kHz (the nominal, published, frequency if possible)
# Call Ident
Those main log items must be shown FIRST with the country shown
LATER in the same line, together with any other (optional) details
such as location, offset and distance.
**IMPORTANT - IF YOU USE THE SIMPLE 'dd' DATE FORMAT.
The input program for REU/RNA/RWW does not allocate the month and year.
The good people who enter the information for us then have to tell the
program what month and year to use. That is not a problem IF ALL
LOGGINGS FOR THE SAME MONTH ARE GROUPED TOGETHER.
So please help us by making sure you separate your December and
January loggings, even if it breaks up some Noah pairs.
Where possible, we suggest that logs are in Radio Country order, instead
of in the usual kHz order, so that the country pairs appear together.
We'll send an ANY MORE LOGS? email at about 20:00 UTC on Friday 3rd
January showing whose logs we have found. Try to post your log to the
List before that so you will get confirmation that it has arrived OK.
Good listening, everyone. Enjoy the CLE.
And finally, radio or not, Joachim and I wish you a very HAPPY CHRISTMAS.

(CLE Coordinator)
Reminder 1:
This is an ideal event to help you qualify for one or more of Joe Miller's
attractive Award Certificates - they make great "wallpaper" for any
listening shack. Joe, our Awards Coordinator, invites us to submit
requests. http://www.ndblist.info/awards.htm will take you to the
different web pages containing the advice you will need.
Certificates can be ordered direct from the REU-RNA-RWW database.
Now is a good time to apply with so many NDBs going off air.
Reminder 2:
You could use any ONE remote receiver for your loggings, stating its
location and owner - with their permission if required.
( e.g. see https://sdr.hu/ )
A remote listener may NOT also use another receiver, whether local
or remote, to obtain further loggings for the same CLE.

DXing The Utilities (Part 1)
The following blog was originally posted in 2015 but might still be of interest to anyone with a shortwave radio! Although maritime CW has all but vanished from HF, ships can still be logged and followed on digital modes, using DSC or Digital Selective Calling.
*******************************
After building the house here on Mayne Island, in the early 90's, it was several years until I was able to set up a dedicated station. In the meantime, I limited my radio activities strictly to listening. I had a nice Icom R-71A set up in a hall closet and spent my radio-time, mostly on weekend evenings, listening to maritime CW, HF aeronautical traffic and, of course, NDBs below the broadcast band.
My HF receiving antenna consisted of three inverted-V's ... one for 160m, the second for 80m and the third for 40m ... all fed from the same coaxial line at the top of a 70' Balsam. It didn't take long to realize what an exceptional radio location I had, living right at the edge of the ocean, with dozens of miles of saltwater in most directions other than due west.
I really enjoyed following evening airline flights across both the North and South Atlantic, and in the early winter afternoons, following the commercial air-traffic all over Africa. Even though listening on 5 or 6MHz, I was amazed at how strong the signals from airliners over Africa at 30,000 feet or more could become, this far to the west. In the early mornings, directions were reversed and traffic from the far east, right into India, was fairly common. Often, small single-engine planes, usually run by various missionaries, could be heard while on the ground, taxiing at remote field locations and calling in via HF radio to request takeoff and flight-following.
Now QSL's have always been one of my top radio interests and it wasn't long before I started sending and collecting verifications for both the aircraft and the ships I was hearing ... once I had figured out how to get my reception reports to their proper destinations.
A very small portion of my 'utility' QSL collection is shown below. For the most part, it consists of PRC's or 'Prepared Reply Cards', with blank portions to be filled-in by the verification signers. Surprisingly, my return rate was around 90% and verifications were often returned with long, hand-written letters and numerous photographs ... especially from the ship RO's, as I suspect their days at sea were often quite monotonous. Even many of the military and commercial aircraft pilots would return a handwritten note along with the filled-in verification card, which I found even more surprising. It seemed that most were very surprised to hear that their radio transmissions were even making it this far and could be heard so readily.
Some of the most interesting catches came from the Pacific, with a large variety of ships operating out of Japan. There are probably still several maritime CW stations operating in Japan. Many of these were owned and operated by commercial fishing companies and could be heard working fleet vessels throughout the Pacific on their daily CW skeds.
This interesting catch from the North Pacific was the Japanese 'fisheries research vessel' 'M/V FUJI MARU'. She was about 1200 miles NW of her CW contact, JNA in Tokyo.
A Japanese cruise-ship, the 'M/V ORIENT VENUS' was logged early one summer morning while working JNA on 8355 KHz CW. Her position indicates she was in the Mariana Islands.
One of my first catches from the Great Lakes
was the 'M/V Oglebay Norton', a huge bulk
carrier out of Detroit. Her 150W signal was loud and clear late one August evening while in contact with WLC, Rogers City Radio.
The U.S. Coast Guard is still one of the best QSLers around.
Several of their stations will QSL with a nice printed card.
NMC (San Francisco) and NMO (Hawaii) were two
catches, regularly heard on the old 500 KHz calling
frequency.
Stormy weather often provided a good chance
to catch a search and rescue mission in progress.
'Rescue 6008' was an HH-60J helo enroute from
Chesapeake Bay to Elizabeth City, North Carolina during
a midnight rescue operation.
Although not my farthest HF maritime catch,
this was one of the most surprising. 'C4PC'
was heard early one February evening on 8 MHz CW, when conditions seemed terrible. No other ships were heard on the band at the time. As I learned later, the 'M/V MAIROULI' was at anchor near Beirut, Lebanon, a distance of nearly 7,000 miles from Mayne Island.

I found Sunday to be a tough one my signal was just not being heard and I am guessing it was just the propagation? The few times I was on the radio on Saturday I had no issues making contacts. Some of the bonus things here at VE9KK were:
- The new Astron power supply worked just fine.
- I was able to work Europe on 40m which never happened at the old QTH with the MFJ 1788 antenna.
- Speaking of antennas it was a joy to use the End fed antenna, I was able to change bands without returning. The magloop I used for so long had to be re-tuned on the same band and for sure on band changes.
- On Saturday (when I was on) I was able to get into Europe, Central America and South America without issue.
During my time on Sunday during the contest I was greeted with an on screen message that N1MM+ stopped working as it was not able to communicate with com3. Com3 is my CAT control for the Icom 7610 and in a nutshell, this meant I was having RFI issues with one or more of my USB cables. I thought I had solved this issue already with snap on chokes?? I had a fast glance at the snap on chokes an noticed some had "un-snapped". I shut things down and spent well over an hour to fix the situation once and for all!! More on that later this week in another post. I restarted the rig and software and did a few tests and I was good to go, but the bands did not seem to want to co-operate. Having said that the bands sure were alive with opportunity. I heard nothing from the south pacific or Asia. Overall, I had a great time while in the chair at the radio and am looking forward to other CW contests.
Hunting For NDBs in CLE250
YMW - 366 courtesy: ve3gop.com |
There is no doubt that as one ages, the passage of time seems to accelerate. Didn't we just have a CLE a couple of days ago?? In any event, this weekend finds CLE 250 focusing on 350.0 - 369.9 kHz, in search of NDBs.
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! We continue to have 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 YMW - 366 kHz. 'YMW' is located in southwest Quebec, near Maniwaki.
'YMW' runs 500W into a massive vertical and is well-heard throughout North America as well as in Europe. Listen for its upper-sideband CW identifier repeated every 10 seconds (with your receiver in the CW mode) on 366.398 kHz.
This past week has seen the best propagation of the season so far. Hopefully it will extend into the CLE weekend ... but, it will be interesting to see if our CLE once again gets whacked by the Sun, just as it gets started. This has been the case for the past several CLEs as our monthly schedule seems synced with some nasty coronal hole on the Sun, also on a ~ 27 day cycle!
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:
Our 250th 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 22 November - Monday 25 November
Times: Start and End at midday, your LOCAL time

Here Comes The ’29 QSO Party!
Saturday, November 9th, as well as the following Saturday (16th), will see the annual running of the Bruce Kelley 1929 QSO Party, otherwise known as the '1929 BK'.
Only transmitters that are 'era-appropriate' are allowed to be used. More specifically, transmitters must employ tubes that were available in 1929 or earlier, and transmitters must be self-excited. No crystals allowed! Crystals were new and largely unaffordable for most hams back in the depression days.
The year of 1929 marked a real turning point in amateur radio as governments finally cracked-down on things such as frequency stability, out of band operations and re-alignment of call districts. In short, hams were henceforth required to behave themselves and to clean up their signals and methods of operation.
courtesy: http://www.arrl.org/ |
If you tune across the CW bands during these two upcoming Saturday nights, you will have the rare opportunity to hear exactly what the bands would have sounded like back in the very early '30s'.
For the most part you will hear single-tube Hartley, Colpitts or TNT oscillators along with a few two-tube MOPAs thrown in. Many of them will suffer the same problems encountered by the boys of '29 ... chirp, drift, buzzy notes and frequency instability from antennas swaying in the wind.
The MOPAs will sound much better but some surprisingly nice-sounding signals can be heard coming from properly tuned and optimised single-tube oscillators. I recall being blown away by the lovely sounding signal I heard from such a rig when first tuning into the BK activity several years ago, only to learn that it was a self-excited Hartley using 1/4" copper tubing for the oscillator tank circuit!
The '29 watering-hole on 80m will be around 3550-3580 kilocycles (be careful not to confuse this with kilohertz!) while the early afternoon to post-sunset 40m activity will be found from 7100-7125 kc. There may even be a few on the very low end of 160m. Although many of these transmitter styles were used on 20m and higher, the BK rule-makers have wisely decided not to inflict these sounds on the present ham populace as it would likely keep the 'Official Observers' busy for several days writing pink-slips.
Like last year, I will set up my Hull Hartley (160, 80, 40m), as I haven't used it much since building the MOPA a few years ago. If it's very windy (almost assured), the Hartley will really sound like 1929!
