What is the maximum bandwidth allowed for amateur radio stations transmitting on USB frequencies in the 60-meter band?

1.0 kHz
2.0 kHz
2.5 kHz
2.8 kHz

The correct answer is: 2.8 kHz

For amateur radio stations transmitting on Upper Sideband (USB) frequencies in the 60-meter band, the maximum bandwidth allowed is 2.8 kHz. This bandwidth limit is put in place to minimize interference with other stations and ensure efficient use of the spectrum, especially since the 60-meter band is shared with various other services. The 60-meter band consists of several specific frequencies that are regulated in terms of both power output and bandwidth to maintain harmony among users. The choice of 2.8 kHz is intentional, allowing operators sufficient bandwidth to accommodate voice communication while still observing the restrictions necessary for shared frequencies. This is important for the effective operation of all users in this band segment, ensuring that communications are clear and do not extend beyond designated boundaries.
