This past weekend's CLE saw noticeably improved conditions compared with the previous event.





With the fall DX season fast-approaching, the combination of diminishing thunderstorm activity and improved propagation provided some interesting catches. Friday night was the best with Saturday having a brief period of favorable prop, while no new stations were heard on Sunday night, the poorest.

It was particularly nice to hear strong signals from the eastern provinces on Friday, highlighted with an excellent signal from 'JT' (390 kHz) in Stephenville, Newfoundland. This long haul east-west propagation can only be found with quite geomagnetic conditions as was the case on Friday.


After examining the geomagnetic 'K' data for Saturday (25th), it's interesting to note that the four catches for that night all coincided exactly with the brief green bar (K= 0-3) centered on the hours around 0900 UTC (circled).

The results from all participants can be found at the NDB List website, or if you are a member of the ndblist Group, results have also been 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 helpful information available there and new members are always very welcome. As well, you can follow and chat with other NDB chasers regarding antennas, techniques, unidentified signals and  nightly propagation.
