    About this estimate

    This is a scenario-planning estimate based on your location, path, time, and expected solar profile. It does not use live propagation measurements, and actual openings can vary with the band, route, and station.

    Band-use reminders

    • Higher bands can look good on paper and still be closed at your station.
    • 40m and 80m often carry regional traffic when 20m feels too long.
    • Always verify your local privileges and segment rules before transmitting.
