Propagation News – 22 October 2017
The latter half of last week saw more settled geomagnetic conditions with the Kp-index declining to one and even zero. This helped the HF bands enormously and there were openings up to and including 12 metres. The upper bands were full of signals, reflecting the better HF conditions associated with autumn. Higher critical frequencies also […]

Last week saw a mixed bag in terms of HF propagation. At the beginning, quiet geomagnetic conditions saw the HF bands alive with DX. With the K-index hovering between zero and one, the ionosphere was showing what it can do during a typical autumn day. There were openings up to and including 12 metres, with […]

Last week saw sunspot activity remain fairly stable, with the solar flux index hovering in the upper 80s. There were no solar flares and so no associated coronal mass ejections either. On the whole, geomagnetic conditions were a little more settled than they have been of late and other than a K-index of four on […]

Last week was a mixed bag in terms of HF propagation. With the solar flux index just into the 90s, amateurs were able to take advantage of the improving autumnal conditions. At times, maximum usable frequencies over a 3,000km path were stretching up to and beyond 21MHz, with openings to the US being reported on […]

Last week saw sunspot numbers decline, but geomagnetic conditions become more settled. This, plus the fact we are heading into autumn, resulted in better HF conditions, with 21MHz opening to DX for short periods. The CS3B Madeira and 4X6TU Israel beacons on 21.150MHz were both audible at times and Jim, G3YLA reports working S01WS in […]
Propagation News – 17 September 2017
After the solar chaos of last weekend, things looked a little more settled at first. However, following last Sunday’s X8.2 solar flare, material from a coronal mass ejection impacted the Earth on Wednesday. The Solar Flux Index declined to 75 by Thursday, but we were seeing the geomagnetic effects of yet another coronal hole as […]
