As has been the case for much of this winter's DX season, LF conditions were very erratic during this past weekend's CLE NDB-listening event.



Geomagnetic activity fluctuated wildly from hour to hour, gradually settling down for Sunday night's last opportunity, with K-indices dropping to 1's or Ø's.

With the DST slowly climbing towards positive numbers after a week of coronal hole streaming and auroral absorption, I had hoped that Sunday night's conditions would be a bit better than they were ... although poor, it was the better of the three nights.

Participants in the central and southern states noted excellent conditions and were not as badly affected as listeners to the north, where the effects of any auroral activity are sudden and much more severe ... I'm always surprised at just how much difference one or two hundred miles further to the south can make.

The following NDB's were heard over the course of the weekend, all using the Perseus SDR to record two-minute grabs, every hour, from dusk through dawn. Going over the recordings takes some time but being able to, in effect, listen all night, readilly illustrates how much the band conditions on LF can change so drastically from hour-to-hour ... sometimes for better and sometimes for worse.

It will be nice to see a 'quiet sun' once again, hopefully sooner than later. For such a wimpy solar cycle, this one is not going down without a valiant fight, as it continues to mess-up LF and MF propagation, with an almost non-stop bombardment of coronal hole streams.

The CLE 200 event this past weekend once again delivered mediocre propagation on all three evenings. In spite of Sunday night's G1-class geomagnetic storm and high K values, Sunday's overnight period proved to be the best of the weekend's generally 'below average' conditions ... this is the time of the year that LF propagation is usually at its best. Thankfully, there are still several months ahead that could offer some really great mid-winter prop.

With the recent mammoth coronal hole finally rotating out of view earlier last week, geomagnetic activity dropped to the lowest level it has been for some time. The K index as well as the DST, couldn't have picked a better weekend to improve, just in time for CLE 199. Conditions below the broadcast band proved to be better than normal in what has been a rather poor month of October propagation. It may be short-lived, as another large coronal hole is now rotating into view on the sun's eastern limb, along with a new active sunspot region ... good news for 10m fans this time of the year, but not so good for LFers.

'ZVR-368kHz' at Vancouver International

It's time for another CLE (Co-ordinated Listening Event) once again! For you low-frequency buffs, another challenge awaits. This month's activity covers the range of  190 - 1740 kHz.


CLE 199 is an 'A-B-C' activity ... a little different from the norm, and listeners are requested to report NDB's from countries, states or provinces, beginning with the letter A, B & C only. Listeners in western NA will find plenty of targets but it might be a challenge for those on the eastern side.

A list of eligible 'A-B-C' entities can be found at the bottom. Additionally, a list of all of the North American targets in this frequency range can be found in the RNA database, while targets for European DXers will be found here ... either chose the 'Seeklist' button or search for the desired state, province or country for detailed frequency information.

A nice target for this CLE is 'ZVR' (368kHz) shown above. The 20W locator from Vancouver International, has been heard from Hawaii to North Carolina. It is located a little east of YVR, in a boggy farmland region.

From CLE coordinator Brian Keyte (G3SIA) comes the following reminder:

Hello all

Almost time for our 11th 'Countries' Listening Event. Whether you are a
regular, or have never sent a CLE log before, your log will be very welcome.

Days: Friday 23 October - Monday 26 October
Times: Start and end at midday, your local time.
Targets: 'Normal' NDBs (190 - 1740 kHz) - not DGPS, Navtex
or Amateur - located in the Radio Countries whose
codes start with A, B or C.

These are our 2-letter codes for the Provinces/States of Canada and USA
and our 3-letter codes elsewhere, including AUS (Australia) -all its States.

The full list of all qualifying countries is given at the end of this email.
Detailed seeklists are available from the Rxx database - just select
SEEKLIST on the CLE page, http://www.ndblist.info/cle.htm
Martin has also added a 'Seeklist Map' facility there too.

If you are in the east of N. America it may be quite a tough challenge.
Most other listeners should be in luck this time, including several who
usually have a hard time.

Please send your CLE log to the List (no attachments and a plain text email
if possible) with CLE199 at the start of its title. Show on each log line:

# The Date (or Day No. 23 to 26)
# The Time in UTC** (the day changes at 00:00 UTC).
# kHz - the nominal published frequency, if known.
# The Call Ident.

**Many of us will be changing our clocks by one hour this weekend
but UTC time continues without any change.

Please show the above main items FIRST on each line of your log.
Any other optional details such as Country, Location, Distance, etc.
go LATER in the same line.
If you send any interim logs, please also send a 'Final' (complete) log.
Always tell us your own location and brief details of the equipment
that you were using.

Do make sure that your log has arrived  by 09:00 UTC on
Wednesday 28 October at the very latest.
I hope to complete making the combined results on that day.

Good listening.
Enjoy the hunt!

(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.

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.
