That's the marine band, including the international emergency calling
frequency of 2182 kHz.  Probably not likely to get re-allocated
any time soon.

The band from 1705 to 1800 is probably needed as a guard
band to keep hams from wiping out broadcast stations,
or vice versa.  (We have a strong station on 1700 kHz
here).

What sacred cow is in the band 1800-1810?
What is going on in JA that keeps them stuck in 1810-1825?
