Hunting For NDBs In CLE 216

CLE 216 NA Targets!




This coming weekend will see another CLE challenge. This time the hunting grounds will be:  320.0 - 334.9 kHz.






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 nice challenge in this one is to hear the White Rock NDB, 'WC', on 332 kHz. The 'WC' NDB is located just a few hundred feet from the Canada - U.S. border, about 25 miles south east of the Vancouver International airport and about 20 miles west of the Abbotsford airport.

The beacon is located on a quiet residential street, nestled between well kept homes and towering fir trees.

'WC - 332' White Rock, BC

Antenna at 'WC - 332'
The antenna is an inverted 'L' end-fed Marconi about 65' in height with a flat top of about 200'. The downlead is barely visible in the above photo as it angles its way back to the transmitter shed. 

Heard regularly in California, 25 watt 'WC' is not as widely reported as is 'XX -344', especially from points east. As the system is similar to what a typical amateur LF installation might be, I would be very interested in any reception reports of 'WC' by DXers to the east. 'WC's upper sideband modulation frequency is ~ 423Hz so look for it on 332.423 kHz with your receiver in the CW mode. 



From CLE organizer Brian Keyte, G3SIA, comes the usual 'heads-up':

Hi all,

Here are all the details for this weekend's co-ordinated listening event.
First time CLE logs too? Yes, please!
Short logs are always as welcome as long ones.

Days: Friday 24 February - Monday 27 February
Times: Start and End at midday, your LOCAL time
Range: 320.0 - 334.9 kHz

Please log the NDBs you can positively identify that are listed in the
frequency range (no DGPS please), plus any UNIDs heard there too.

Send your CLE log to the List, if possible as a plain text email and
not in an attachment, with CLE216 at the start of its title.
Please show on EVERY LINE of your log:

# The date and UTC (the day changes at 00:00 UTC).
# kHz - the beacon's nominal published frequency, if you know it.
# The Call Ident.

Show those main items FIRST on each line, before any optional details
such as the NDB's Location, Distance, Offsets, Cycle time, etc.
As always, make your log meaningful to everyone by including your
own listening location and details of your receiver, aerial(s), etc.
(It would be OK to use a remote receiver, with the owner's permission if
necessary, provided that ALL your loggings for the CLE are made using it).

I 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. Do make sure that
your log has arrived on the List at the very latest by 09:00 UTC on Wed. 1st
March. The combined results should be completed later that day.

Remember that you can find all CLE-related information from the Group's
CLE page ( http://www.ndblist.info/cle.htm ), including a link to the seek
lists provided for this Event from the Rxx Database.

Good listening

(Reminder: You could use any one 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 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. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

The very active Yahoo ndblist 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.

If you are contemplating getting started on 630m, listening for NDBs  is an excellent way to test out your receive capabilities as there are several NDBs located near this part of the spectrum.

You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

'First-time' logs are always VERY welcome!

Reports may be sent to the ndblist or e-mailed to either myself or CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above.

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.

Good hunting!
