222 MHz to 225 MHz is an amateur band only in the United States.
Equipment
Because 222 MHz is only available to amateurs in the United States, very little currently-manufactured equipment supports it; examples include the Alinco DR-235T and the Kenwood TH-F6A. Many amateurs, especially those who do weak-signal work, use transverters on this band.
Modulation
Like the 6 metre and 2 metre bands, operation is typically CW and SSB in the lower band and FM in the upper band.
Propagation
Primarily line of sight, although enhanced modes do exist. There is no F2 propagation on this band, but troposphere ducting and aurora exist.
