Hunting For NDBs In CLE187

VR-266 Vancouver Int'l (50W) - heard as far east as NC
How time flies...once again it's time for the monthly Co-ordinted Listening Event (CLE) for NDB hunters....the 187th event. These always interesting and popular affairs take place over three nights, with this one starting on Friday, October 24th at local noon and running until Monday, October 27th, local noon.

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
This time, it's a two-part activity, should you decide to chase normal DX beacons as well as those from your own country or state/province. Here are the details. 

Days: Friday 24th October - Monday 27th October
Times: Midday on Friday to Midday on Monday, your LOCAL time
QRG: Normal LF/MF frequencies (190 - 1740 kHz)
NDBs: Normal DX and 'HOME' ones (not DGPS, Navtex or Amateur)

Please try to log NDBs that are over 2,000 km / 1,250 miles from you.
If you have a wall map in your shack, you could draw a circle on it.
It will be accurate if it is a great circle map centred on your location.
(There are other easy and very good ways to find which NDBs qualify
for you - I will describe them in the Final Details email)

Please also try to log NDBs in YOUR OWN radio country. For listeners
in AUS, CAN and USA, that means your State or Province.
It will be trivial for a few of us in tiny radio countries, very challenging
for a listener in, e.g., RUS (Eu). Most of us should have a fair list to
try for.
If we also mention any of our home regulars NOT heard, it will help
others to know about NDBs that are not currently active.

If you report on both parts, DX and HOME, I suggest you put them in
separate parts of your log. As usual, any UNIDs that you come across
will also be of interest - in a third part of your log.

Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted here a few days after the event.

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. 

Reports may be sent to the ndblist or e-mailed to either myself or CLE co- ordinator, Brian Keyte (G3SIA). It was very exciting to see two new reporters to last month's event after reading about the CLE right here. Hopefully there will be more first-time reporters for upcoming CLE187.

Please...don't be shy and do 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.
