Excellent HF conditions greeted hams in the ARRL 10-Meter contest
last weekend. Recent indicators show a sudden shift to two digit
daily sunspot numbers from three, and although there is nothing
significant about 100, it makes one notice.
All daily sunspot numbers this week were 97 or less.
Perhaps this indicates a move off of solar maximum, or to a future
with a second maximum.
Solar activity was way...
Average daily sunspot number plummeted to 104.4.
Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere for December 12, 2024 from OK1HH:
"The high solar activity in October this year suggests that this may have been the peak of an 11-year cycle. This is not to say that solar activity will not continue to rise. On the contrary, it may well be that the first maximum of the...

ARRL Director of Development Kevin Beal, K8EAL, says that upped the ante. “It's quite clear that even with the generosity of the donors in attendance...

I2SCROOGE e lo spirito del Natale
Alberto Zagni, I2KBD
L’editoriale di dicembre è solitamente motivo di riflessione e di bilanci dopo un anno di attività. Ho pensato per questo di chiedere ai colleghi del CDN di condividere quello che avrebbero scritto in una letterina per Babbo Natale, i loro desideri e magari la speranza di un piccolo miracolo natalizio come regalo.
