Theory vs reality
VOACAP vs. live spots on one map
Dashed arcs show where the official VOACAP model says the band should work from your current QTH. Solid live spots show where stations are actually being heard. Gaps between the two are where things get interesting.
VOACAP arcs enabledBest on 10m, 15m, 20mUses current UTC hour
VOACAP layer
Dashed lines are generated from the official VOACAP point-to-point engine and colored by reliability.Live spots
Spot markers remain the ground truth. If a spot lands outside the predicted arc, the band may be getting help from short-term or exotic propagation.Best use
Start on 20m, then switch to 15m and 10m when solar flux is strong. Use the map control dock to toggle the overlay on and off instantly.
