Propagation News – 8 December 2024
We had another week of high solar activity but limited geomagnetic disturbances. This meant that the upper HF bands were playing ball all week. The Kp index only exceeded four on one occasion, on the 30 November when it hit 4.67, but otherwise it has been low. And with a solar flux index mainly in […]

Last weekend’s CQWW CW contest was a reminder of just how good HF propagation can be near sunspot maximum. The whole world was workable on the contest bands up to 10 metres, including the Far East, Australasia, the Caribbean and South America. It was a great opportunity to increase your DXCC total and have fun […]
Propagation News – 24 November 2024
We’ve had yet another week of relatively calm geomagnetic conditions. The solar flux index has been in the 160s and despite having 14 M-class solar flares over seven days, we haven’t had any coronal mass ejections to contend with. As a result, the daytime maximum usable frequency, or MUF, over a 3,000km path has been […]

The solar flux index took a downturn this week, ending up at 150. The visible solar disk is looking rather bare compared with a couple of weeks ago. This is the lowest SFI value since the 2 May 2024, but it is only a matter of time before we see another sunspot appear as we […]
Propagation News – 10 November 2024
We had another week of high solar flux and good conditions on HF. Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6 November, but the event was not responsible for a coronal mass ejection (CME). The Kp index remained below 4.5 […]
Propagation News – 3 November 2024
Last weekend’s CQWW SSB contest showed just how good autumnal HF conditions can be. Many contesters worked more than 100 countries or DX entities on each and every HF band. With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as […]
