NDB DXing & The CLE183 Results

WC - 332KHz White Rock, B.C.
The recent three-night NDB listening event (covering 320-335KHz) was dominated with very high noise levels from the numerous thunderstorms across North America. Although propagation was good, all participants struggled with the lightning noise, as is usually the case when listening on LF during the summer monhts.

One of the beacons in my log this weekend is pictured above - 'WC' in White Rock, B.C. The beacon is located in a residential neighborhood, with homes on both sides...not a typical NDB location.

Here is my short log, all captured using Perseus:

Some might wonder why listening for NDB's would be of any interest. For me, there are a number of reasons:
 
  • the challenge of hearing distant low-powered transmitters below the broadcast band, particularly from one region...for me it is Alaskan NDBs
  • the necessity to develop an efficient receiving antenna has led to numerous antenna trials using loops and wires in various configurations
  • learning about LF propagation and how it compares with HF
  • the ability to compare what is being heard at my location with what is heard just a few hundred miles away can often be surprising (and humbling)

If you are planning a 630m station, listening for NDB's is a good way to test your system's receive capability as there are hundreds of signals to be heard, many of them very close to our new 472KHz band.
