#Band Edges

Every amateur band has an upper and a lower limit, and the limits depend on the ITU Region and on your national licence. A QSO logged outside the limits can be questioned by the contest committee, even when the cause is only a typing or logger error. The articles under this tag explain the idea of band edges in general terms and show how to check the frequencies in your own log. Always confirm the current limits in your licence conditions. Treat any numbers as general guidance.
