General exam question G1C03
Subelement G1, COMMISSION’S RULES· Group G1C · 47 CFR §97.303(h)(1)
What is the maximum bandwidth permitted by FCC rules for amateur radio stations transmitting on USB frequencies in the 60-meter band?
- A.2.8 kHz (correct answer)
- B.5.6 kHz
- C.1.8 kHz
- D.3 kHz
WhyUSB voice transmissions on the 60-meter band are limited to a maximum occupied bandwidth of 2.8 kHz. 60 meters is channelized and restricted to a maximum occupied bandwidth of 2.8 kHz for USB voice under §97.303(h)(1), narrow enough to fit cleanly within each channel's boundaries, answer A. The wider figures in B and D would spill outside a channel, and 1.8 kHz in C is narrower than the rule actually requires.
