About this app

DXSun is a lightweight app designed for amateur radio operators to monitor real-time solar and geomagnetic data that influence HF and VHF radio wave propagation.

The information is clearly presented across three main tabs:

HF: propagation conditions, SFI, A and K indices, and band openings.

Solar: solar activity, sunspots, solar flux, and alerts.

VHF: tropospheric scatter conditions, MUF index, and more.

All data is retrieved from the public source HamQSL.com and updated periodically.

You can configure alerts on most of the parameters that get triggered when condition is met.

The main indicators can be displayed on a time chart.

No ads, no login required, and no personal data collected.
