CLE 208 Results




This past weekend saw another of the monthly CLE listening challenges.






'CLE's' are 'Co-ordinated Listening Events', and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

If you are interested in building a 630m system, doing some listening on the high end of the NDB band is a great way to evaluate your station's receiving performance.

The frequency range covered for CLE 208 was 400-419.9 KHz where a fair number of North American NDBs' can be found. Beacons at this end of the band also tend to propagate better than those at the lower end near 200KHz.

This weekend, typical summertime conditions prevailed, with extremely high levels of thunderstorm / lightning QRN ... propagation itself was not too bad for the middle of summer.

As usual, I set up my Perseus SDR for hourly two-minute captures of the allocated spectrum and spent a few hours going over the files during the day. I have yet to purchase and download the latest version of Perseus software but I understand that there are several improvements over the system I am using ... which is excellent for my present needs.

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 NDB list Group, results will also be e-mailed and posted there.

The very active Yahoo NDB list Group 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.
