Propagation News – 7 January 2018
Last week the solar flux index (SFI) hovered around the 70 mark, reflecting the lack of sunspots. Given that the SFI doesn’t really fall below about 65-66 at sunspot minimum, this shows the distinct lack of solar activity at this time. This meant that the lower bands were the ones to see the most activity, […]

This week we have a slightly different approach to the HF propagation news. We want to help you and your family contact Santa’s elves in Lapland. The station Oscar Juliet Nine X-ray is on the air this Christmas from Santa Claus Land. Up to 30 elves are operating OJ9X from Finland for the entire month […]
Propagation News – 17 December 2017
Last week, the solar flux index nudged into the low 70s, although the Sun remained spotless. The enhanced solar wind from a coronal hole pushed the K-index to four, and it remained around three for long periods during the week. So these were far from ideal conditions for F2 layer DX on the higher bands, […]
Propagation News – 10 December 2017
Last week, the effects of the high-speed solar wind from another coronal hole saw the K-index climb to five on Tuesday and remain relatively high throughout Wednesday and Thursday. The ionosphere took a hit and daytime maximum usable frequencies struggled to exceed 18MHz at times. By Thursday, conditions were starting to improve a little, but […]
Propagation News – 3 December 2017
HF propagation for last week’s CQ Worldwide CW contest was fair to middling. There was a 10 metre opening on Saturday, but otherwise the money bands were 20 and 15 metres during the day, with 40 and 80 metres coming into their own after sunset. The predicted poorer geomagnetic conditions on Sunday didn’t really materialise, […]
Propagation News – 26 November 2017
The Solar Flux Index remained in the 70s last week, reflecting the continued absence of sunspots. Geomagnetic conditions were unsettled at the beginning of the week, but improved as the effects of a coronal hole passed. We were left with a mixed bag of HF propagation, with fair conditions at times and poorer ones at […]
