Propagation Chrome extension

HF and VHF band conditions in your browser toolbar — same data feed as our propagation dashboard, without opening a full page.

Built for operators who want a quick glance at day/night band hints, solar flux, and K-index before they spin the dial. Optional favourite bands, light/dark theme, and links to PSK Reporter and friends.

Install in Chrome

We are working toward the Chrome Web Store. Until then, install from source — takes about two minutes.

  1. Download the extension: ZIP from GitHub (or clone the repo).
  2. Unzip so you have a folder containing manifest.json.
  3. Open chrome://extensions in Google Chrome.
  4. Turn on Developer mode (top right).
  5. Click Load unpacked and select that folder.
  6. Pin the RadioForUs icon on the toolbar — click it for band conditions.
Chromium browsers (Edge, Brave, etc.) use a similar load-unpacked flow. Firefox is not supported yet.
