| CCIR Selcall | CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R) selcall consists of CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R)-1, CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R)-2, and PCCIR, which are 5-tone selcall modes for VHFVery High Frequency (30-300 MHz)/UHFUltra High Frequency (300-3000 MHz) radios. CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R)-1 and CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R)-2 only differ in the tone duration, and PCCIR only differs in the group, reset, and repeat tone frequencies. | 30 MHzMegaHertz (MHz) 10^6 Hz — 800 MHzMegaHertz (MHz) 10^6 Hz | NFMNarrowband Frequency Modulation | MFSKMultiple Frequency Shift-Keying | 5 kHzKiloHertz (kHz) 10^3 Hz | Worldwide |  |
