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
