The maximum bandwidth of an amateur radio station's transmission allowed in the band 144 MHz to 148 MHz is:

In the 2-meter VHF band (144 MHz to 148 MHz), the maximum permitted bandwidth for an amateur radio transmission in Canada is 30 kHz. Because VHF bands offer significantly more frequency space than HF bands, regulators allow wider bandwidths. This easily accommodates standard FM voice communications, wideband packet radio, and other modes that require more spectrum. If you see choices like 6 kHz or 20 kHz, remember that these are restrictive HF limits. VHF and UHF bands generally start at 30 kHz limits to support higher-fidelity and higher-speed modes.
