Live HF Propagation Matrix, DMR Tickers & APRS Node Tracker
Standard operation synchronization time.
18-beacon global network, 10s slots per band, 15 min full cycle. Calculated locally from UTC โ no API required.
Dates are indicative โ confirm exact weekends on the WIA site each year.
WICEN (Wireless Institute Civil Emergency Network) coordinates amateur radio volunteers during bushfires, floods, and other declared emergencies across VK states.
Always follow your local WICEN group and RFS/SES for activation status โ this card is reference only, not a live feed.
Useful for planning grey-line DX windows on 40/80/160m.
Next AOS for ISS, SO-50, AO-91 & AO-92 โ real SGP4 propagation from live Celestrak TLEs, computed entirely in your browser.
Brandmeister's Last Heard feed runs over a push socket protocol, not plain HTTP โ it can't be embedded in a static page without a backend. Use the live dashboard directly:
YSF reflector activity isn't published as an open CORS-friendly JSON feed. Check current reflector status directly:
Saved to this browser's localStorage only โ nothing is sent anywhere, and settings don't sync between devices.
Where the APRS map and satellite location default to on page load.
Built by VK4AHA for the Hack Club Stardance program. Live data sources: aprs.fi (station tracking, key required), POTA/SOTA public spot APIs, wspr.live, and dxsummit.fi. Satellite passes use live TLEs from Celestrak with SGP4 propagation via satellite.js, computed client-side โ no backend, no tracking, no accounts.
