What is the maximum bandwidth for a data emission on 60 meters?
The correct answer is D: 2.8 kHz. The maximum bandwidth for a data emission on 60 meters is 2.8 kHz. 60-meter channels are narrow, and data emissions are limited to 2.8 kHz bandwidth. For amateur radio operators, this is important for 60-meter operation. Understanding this helps ensure legal 60-meter operation.
Exam Tip
60m data emission maximum bandwidth = 2.8 kHz. Think '6'0m 'D'ata = '2'.'8' kHz. 60-meter channels are narrow, and data emissions are limited to 2.8 kHz bandwidth. Not 60 Hz, not 170 Hz, not 1.5 kHz - just 2.8 kHz.
Memory Aid
"60m data emission maximum bandwidth = 2.8 kHz. Think '6'0m 'D'ata = '2'.'8' kHz. 60-meter channels are narrow, and data emissions are limited to 2.8 kHz bandwidth. Important for 60-meter operation."
Real-World Application
A data emission on 60 meters: The maximum bandwidth permitted is 2.8 kHz. This is a narrow bandwidth limit - 60-meter channels are narrow, so data emissions must fit within 2.8 kHz. Wider bandwidths are not permitted. 2.8 kHz is the maximum - this is the bandwidth limit for 60-meter data emissions.

Why Other Options Are Wrong
Option A (60 Hz): Incorrect. 60 Hz is way too narrow - 60-meter data emissions can be up to 2.8 kHz. 60 Hz is too narrow.
Option B (170 Hz): Incorrect. 170 Hz is too narrow - 60-meter data emissions can be up to 2.8 kHz. 170 Hz is too narrow.
Option C (1.5 kHz): Incorrect. 1.5 kHz is too narrow - 60-meter data emissions can be up to 2.8 kHz. 1.5 kHz is too narrow.
