Last weekend's CLE 230 overall results have now been tabulated. Reports from European NDB hunters and those from North America and the rest of the world may all be found here at the NDB List info website.


If you have joined the NDB List group, a copy of these will have already been sent to your mailbox.

It seems that compared to the last time these same frequencies were searched (CLE 213 Nov '16), my results were a little poorer, with 36 beacons heard this time versus 52 for the previous effort.

Propagation varied over the three night event depending upon what part of the world you were listening from and as usual, when there has been some recent coronal hole induced geomagnetic disturbance, the further away from the auroral zone you were, the better the prop seemed to be. The third and final night saw summer-like lightning noise for most North American listeners and the next several CLE weekends will be  lucky to escape these rising levels until late in the fall ... but don't give up as there can be some great propagation in the summer and those quiet nights do come around when you least expect them.

In spite of the poor propagation here, there were some unusual quirks. Many of the 25 watt, normally easy NDBs from the central and southern states, were missing in action ... yet on all three nights, both FIS in Key West, Florida and SQT, up the coast on Florida's central eastern shoreline, were easy copy for several hours.

I can only guess that the reason for this is that both of these are 'big' beacons ... big antennas and power in the 300W plus class. They just managed to power through in spite of the poor propagation.

FIS - 332 kHz Key West, Florida (aka: The 'Fish Hook' beacon)

SQT - 257 kHz Melbourne, Florida

The other surprise was a loud signal on all three nights from FS in Sioux Falls, South Dakota, yet there was not even a hint of many of the other regular midwestern stations. Its reported 300W and 60' vertical is no doubt the reason. 

FS - 245 kHz Sioux Falls, South Dakota

How DD in Columbus, Ohio managed to sneek through is a bit of a mystery but it looks like her 50W and classic 'T' was enough to do the trick.

DD - 253 kHz Columbus Ohio

I managed only 36 stations but spent little time on Friday since conditions were truly dreadful.

As usual, my receiver of choice was the Perseus SDR in combination with my MF inverted-L, tuned to 300kHz.

The very active NDB Group.io List 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.
