WSPR Antenna Lab is a high-performance web dashboard designed for radio amateurs to compare the real-world propagation characteristics of two different antenna systems using the global WSPR (Weak Signal Propagation Reporter) network.
-
Real-time Delta Gain (
$\Delta G$ ): Objective comparison between your antenna and a reference station. - Polar Radiation Pattern: 360-degree visualization of signal gain with adjustable beamwidth smoothing.
- Low-Angle Analysis: Distance-SNR correlation using linear regression to identify antennas better suited for DX (low-angle) vs. regional (high-angle) propagation.
- Dynamic Thresholding: User-definable Local and DX zones for precise propagation analysis.
- Signal Propagation Map: Interactive great-circle path visualization of received signals.
- "Match Mode" Logic: High-precision analysis focusing only on spots where both antennas were documented by the same receiver in the same time slot.
-
SNR Normalization: Automatically adjusts for power differences (
SNR - Power) for a fair comparison. - PWA Support: Fully optimized for mobile use, including Apple devices.
- Callsign A: Enter your primary station callsign.
- Callsign B: Enter a nearby reference station.
- Filter: Select band and time window (up to 24 hours).
- Analyze: The dashboard fetches data directly from WSPRnet and calculates metrics in real-time.
- Frontend: React + Vite + Tailwind CSS
- Charts: Recharts
- Maps: React Leaflet
- Backend: Express (API Proxy)
