## Description

DXAlert – Propagation Conditions
  
  Stay ahead of band openings with real-time solar and geomagnetic data from
  NOAA Space Weather Prediction Center.

  Whether you're a CB radio operator, ham radio enthusiast, or just curious
  about propagation, DXAlert gives you the key numbers you need — updated live,
  straight from official NOAA sources.
  
  What DXAlert monitors:
  • Solar Flux Index (SFI) — how active the Sun is today
  • Planetary K-index — geomagnetic disturbance level
  • Estimated A-index — daily geomagnetic activity
  • Sporadic-E seasonal likelihood — is Es season active?
  
  Bands covered:
  • CB (27 MHz) — Sporadic-E & F2 skip
  • 6m — Es + ionospheric conditions
  • 2m & 70cm — ionospheric activity context

  Features: 
  • Live dashboard with visual condition gauge
  • All-bands overview at a glance
  • Historical SFI and Kp charts (up to 30 days)
  • Background alerts when conditions exceed your thresholds
  • No account required, no subscription, no ads
  • Data: NOAA SWPC (free, public)

  Honest about limitations: Sporadic-E cannot be reliably predicted from solar
  data — DXAlert shows a seasonal climatology estimate, not a live Es detection.
  For confirmed openings, check DX cluster spots and beacon monitoring.

  Also from DameAppku: TropoDX — tropospheric ducting forecasts for 2m and 70cm.
