About HF guide
A quick-look HF propagation compass. SFI and Sunspots lift the ionosphere. K and A describe geomagnetic disturbance.
What to do now?
- High SFI + low K/A — try higher bands: 20 → 15 → 10 m
- Rising K/A — go lower: 40/60/80 m or digital modes
- MUF near band edge — timing matters, check hourly
Reading the KPIs
- SFI / SSN — higher = more ionisation, better high bands
- K / A — higher = more disturbance. K ≥ 4 means rough going
- Solar Wind — sustained fast wind raises K/A potential
- foF2 — F-layer vertical ceiling, strong day/night variation
- MUF — highest usable freq for ~3000 km. MUF ≈ 3 × foF2
