CLE 226 / CLE 227 NDB Listening Event Results

 
CLE 226 and CLE 227, both running during the Christmas to New Year period, produced some excellent propagation on the MF NDB band in most parts of the world.


With the Sun behaving itself and acting more as it should for this time of the cycle, even the high latitude prop-challenged southwestern region of British Columbia enjoyed unusually good propagation. In fact, the night of January 1st was probably the best propagation I have seen on the NDB band in several years!

That night was particularly good to the east resulting in my first logging of a New Jersey NDB ... 50 watt RNB at Millville, on 363kHz.


In keeping with the Christmas spirit, CLE 226 was a north 'polar' event, with NDB's within the Arctic Circle being the targets.

Being away from home for several days, I missed out on the first four nights and got started on December 29th, but over the next few nights heard the following polar stations:

Here is the Cambridge Bay NDB (CB) on 245kHz. As well, the much weaker Gore Bay, Ontario NDB (YZE) can be heard underneath.


The second half of the event, CLE 227, was a 'bearing' event, where each listener picked one bearing from their location and logged NDBs (10 maximum) in countries or states that were located or touched on that bearing.

Since the normal propagation from my location favors the southeast, I chose a bearing of 107 degrees. This bearing passes through BC, WA, ID, MT, WY, NE, SD, KS, MO, AL, AR, TN, MS, GA, FL, BAH and BRAZIL, giving me a lot of possible coverage. As the propagation favored the east as well, I might just as well picked one that went through the Great Lakes and the eastern provinces. As it turned out, beacons were heard in most of my chosen regions except for the Bahamas.

Further illustrating just how good conditions were, three NDBs in Brazil were heard here, my first ever loggings from that country.

As usual, my receiver of choice was the Perseus SDR in combination with my MF inverted-L, tuned to 300kHz. After listening to many hours of NDB recordings during the event, I was hearing CW coming from all sorts of things in the house, including the ceiling fan and the washing machine for the next several days!

More information on this particular CLE as well as NDB listening in general can be found at the NDB List website.

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.
