Stations settings. Move stations by dragging the markers, by entering the locator, or directly the hamradio callsign below.

Stations
MUF & foF2 Short path curves For the short path (shortest path between TX and RX), the curve indicates the theoretical possible frequency range (vertical y axis in MHz) for achieving a long distance contact by bounces of 3000 km (horizontal x axis is the TX to RX path in km).
path is workable & usable frequency bandwidth (MHz)
⭕️ path is poor, not suitable

24-hour reliability predictions

Displays 24-hour predictions of the probability of making contact between two stations in Short Path.

Monthly smoothed sunspot numbers taken into account, but not Daily sunspot numbers, not A, K indices. Use the arrow pointing to the right.

In the settings, choose the type of station that is closest to yours.

MUF & foF2 Long path curves For the long path (longest path between TX and RX), the curve indicates the theoretical possible frequency range (vertical y axis in MHz) for achieving a long distance contact by bounces of 3000 km (horizontal x axis is the TX to RX path in km).

✓ the band can be currently used for long distance contact between the two markers
? the band is at the limits but might be tried to make contact between the two markers
