Compiled by G0KYA, G3YLA and G4BAO on 23 September. As we head towards the end of September, we are seeing daytime maximum usable frequencies, or MUFs, starting to climb. The daytime MUF over 3,000km is reaching 12m and is just touching 10m at times. Within a few weeks we can expect it to reach 10m […]

Compiled by G0KYA, G3YLA and G4BAO on 17 September, 2026 Thursday, 17 September marked a milestone in terms of the solar flux index. On this day the solar flux index fell to 100. This is more psychological than important but it is a sign that the solar flux index is falling from the dizzy heights […]

Compiled by G0KYA, G3YLA and G4BAO on 10 September 2026. As we head into September, autumnal HF conditions are fast approaching. We can expect the maximum useable frequency, or MUF, to climb during the day and DX to become more plentiful. However, we are not there yet and it may take a few more weeks […]

Compiled by G0KYA, G3YLA and G4BAO on 3 September 2026. Solar activity has continued to decline, leaving us with a solar flux index around 100. The upside is we haven’t had any solar flares and associated coronal mass ejections, or CMEs, to contend with. Over the last week, we had only one M-class flare and […]
