📊 Cross-Station Comparison
Each radar shows the 16-sector P90 distance profile for that station on the selected band — the “reach shape” of the antenna. North is up. Equal radius in every sector ≈ omni; strong lobes ≈ directional. Compare side-by-side to see whose antenna is hearing in which directions.
All participating stations overlaid on the same polar chart for one band. Useful for spotting group-coverage gaps — directions where every station is weak.
Each row is one station. Each cell is one Eastern-time hour over the last 7 days; darker = more spots. Reveals when each station is on the air and when each is hearing best.
Histogram of receive distances (miles) for each station, 0 → 12,400 mi in twelve buckets. A right-shifted curve = more DX; a left-leaning hump = mostly regional reception.
Each station’s unique receivers are plotted with that station’s color. Click a marker for the call & distance. Click a station chip above to toggle its dots on or off; filter to one band to compare reach on that band only.
Every spot classified by likely propagation mode (distance + band + UTC hour). Each row is one station’s mix on the selected band. Useful for spotting who’s working DX vs. who’s stuck in regional NVIS or single-hop F₂.
