CLE 220 Results

Last weekend's midday CLE seems to have drawn a lot of interest for a summer event. 

Perhaps it was because listeners could participate without having to burn the midnight oil as is usually the case when listening 'live' and not recording with an SDR. 

Listening time was restricted to between 1100 and 1500 hours local time, to see what could be heard via daytime groundwave.

In spite of having a low noise seaside listening location, I was surprised to only hear beacons in B.C. and Washington state, with not as much as  a whisper from Oregon, Alberta, Idaho, Montana or lower Alaska. The furthest beacon I heard was ZZP-248 in the Queen Charlottes, at 486 miles. I would have wagered that most regions would see similar results, with groundwave distances being fairly constant throughout North America, but this was not the case.

Participants in the central states seemed to enjoy much greater groundwave coverage than here on the west coast. It seems that the rugged Coastal ranges and the Rockies do have a pronounced effect on daylight propagation when skywave is not involved. Beacon ERP cannot be ignored as well as location and ground system efficiency ... some definitely get out much better than others even though output powers may be the same.

Anthony Casorso, ADØVC, listening near Denver, Colorado with an Elad SDR and a 17' Low Noise Vertical (LNV), managed several +500 mile catches but all N-S or to the east.

Bill Riches, WA2DVU, in Cape May, NJ, found SJ-212 in Saint John, New Brunswick, 635 miles to the north with his Perseus and Wellbrook loop.

Dave Tomasko, K9QU, in Galena, Illinois, caught OKS-233 in Oshkosh, NE at 625 miles and FOR-236 in Forsyth, Montana, at a whopping 845 miles with his R-75 and Wellbrook ALA100 loop. 

These were heard here at 11 a.m. local time using my Perseus SDR and inverted-L tuned to 300kHz:
