AM expanded band

The extended mediumwave broadcast band, commonly known as the AM expanded band, refers to the broadcast station frequency assignments immediately above the earlier upper limits of 1600 kHz in International Telecommunication Union (ITU) Region 2 (the Americas), and 1602 kHz in ITU Regions 1 (Europe, northern Asia, and Africa) and 3 (southern Asia and Oceania).

In Region 2, this consists of 10 additional frequencies, spaced 10 kHz apart, and running from 1610 kHz to 1700 kHz. In Regions 1 and 3, where frequency assignments are spaced 9 kHz apart, the result is 11 additional frequencies, from 1611 kHz to 1701 kHz.
