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 gear is manufactured that supports it. The only 222 rig currently in production is the Alinco DR-235T, although a number of used models are available. 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.
