Amateur Radio (1.25 m Band)

Current Use
222–225 MHz Amateur radio 1.25 m band
According to the ITU, "where allocated, this band serves as an alternative to the 144 MHz band for short-range communications."

In the U.S., the ARRL has adopted the following band plan. This plan may apply in other countries as well:

Frequency (MHz): Use
222.0-222.15: Weak-signal modes
222-222.025: Earth-Moon-Earth communications
222.05-222.06: Propagation beacons
222.1: SSB & CW calling frequency
222.1-222.15: Weak-signal CW & SSB
222.15-222.25: Local coordinator's option; weak signal, ACSB, repeater inputs, control
222.25-223.38: FM repeater inputs only
223.4-223.52: FM simplex
223.52-223.64: Digital, packet
223.64-223.7: Links, control
223.71-223.85: Local coordinator's option, FM simplex, packet, repeater outputs
223.85-224.98: Repeater outputs only
