HF Propagation Map - Live Band Activity & Signal Reach

HF Propagation Map - Help

Zones: These are general polygon areas representing signal reachability by band and mode (e.g., FT8, CW). Best for wide coverage views.

Summary: This shows aggregated signal strength and activity per 4-character grid (e.g., CM87). Use this to get a quick high-level overview of band conditions.

Cluster: This shows directional activity centered around a specific grid (entered as "Perspective"). Ideal for assessing where signals are coming from/to, based on your location.

MUF: This view shows the estimated Maximum Usable Frequency (MUF) per grid based on real signal paths. Ideal for spotting high-frequency openings in real time.

How to use:

• Select a view mode: Zones, Summary, or Cluster.
• Choose a band to filter by (or "All").
• For Cluster view, enter a valid 4-character grid (e.g., CM87) and press Enter.
