Static Frequency Markers

0 / 6

Pin fixed frequencies across every chart (snaps to the closest data point) — handy for comparing bands or points of interest side by side.

Chart Zoom Span

Type a span (MHz) to zoom every chart in around the active frequency. Scroll/pinch on any chart still works too.

Amateur Band Highlights

Shades ham band segments across the frequency charts. Edges vary by country/license class — treat as a general reference.
