It seems that our medium-frequency NDB CLE's (Co-ordinated Listening Event) go hand-in-hand with solar disturbances and wacky geomagnetic conditions. If you want to know when the next big geomagnetic upset will be, just check the date of the next CLE!


Along with a half dozen M-flares and auroral-producing 'K' indexes of 5-6, most of North America was blanketed with severe thunderstorm activity, always typical of this time of the year. In spite of the poor conditions, several signals did manage to find their way into my log. Sunday night provided the best conditions, with far less thunderstorm activity and a slight improvement in propagation. Saturday night's lightning map looked like this:

Loggings in RED where made on Friday night, GREEN on Saturday night and BLUE on Sunday night.

All stations were heard on the Perseus SDR while using my LF 'inverted-L' resonated at 300KHz.

Thankfully, by this time next month and into October, quieter nights and better propagation will prevail ... fall often produces the best propagation of the year and has always been my favorite time of the year, outdoors and at the dials.
