What is the maximum authorized bandwidth on the 6-metre and 2-metre bands?

On the VHF bands such as 6-metres (50 MHz) and 2-metres (144 MHz), the maximum authorized bandwidth for a transmitted signal in Canada is 30 kHz. These bands have significantly more available spectrum than the HF bands, allowing for wider emissions. Because of this extra space, operators can use modes like frequency modulation (FM) voice, which require larger bandwidths to provide clearer, static-free audio. In contrast, HF bands generally restrict bandwidth to much narrower limits (typically 6 kHz) to accommodate more users in a smaller frequency space.
