What is the maximum bandwidth an emission may occupy on the 60 m band?

2.8 kHz for all 60 m spectrum.

  1. 500 Hz
  2. 6 kHz
  3. 2.8 kHz ✔

Why: Rule 97.303(h) says amateur emissions on 60 m may not occupy more than 2.8 kHz. That is about the width of one SSB voice signal or a typical digital mode.

Huh, didn't know that: Power on the four 60 m channels is limited to 100 W ERP, and to 9.15 W ERP in the 5351.5 to 5366.5 kHz segment.
