222 MHz to 225 MHz is an amateur band only in Region 2. Countries where 222 MHz operation exists include the United States, Mexico, Central American nations, Caribbean nations, and Brazil.
Equipment
Because 222 MHz is only available to amateurs in Region 2, very little currently-manufactured equipment supports it. Examples include the Alinco DR-235T, the Kenwood TH-F6A and the U.S. versions of the Yaesu VX-7R and VX-6R HT. 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
222 MHz propagation is primarily line of sight, although enhanced modes do exist. There is no F2 propagation on this band, but troposphere ducting and aurora exist.
