What are the standard bandwidths used on the various amateur bands?

For example, FM on 2 meter generally uses about 3kHz, right?

The standard bandwidths are:

  • SSB: about 2.5kHz
  • AM: about 10kHz
  • FM: about 15kHz
  • CW: about 50Hz
  • Data: varies greatly, from a few Hz on up...

The deviation of narrowband 2 meter FM is about 5kHz, but the total bandwidth is around 15kHz.
