Deep Dive: G1A02
The correct answer is B: 30 meters. Phone operation is prohibited on the 30-meter band. The 30-meter band (10.100-10.150 MHz) is restricted to CW and digital modes only - no voice (phone) operation is allowed. This restriction helps prevent interference with other services that share the band. For amateur radio operators, understanding this restriction is essential for legal operation. The 30-meter band is unique in having this phone prohibition.
Why Other Answers Are Wrong
Option A (160 meters): Incorrect. Phone operation is allowed on 160 meters in the General/Extra phone segments. Option C (17 meters): Incorrect. Phone operation is allowed on 17 meters in the appropriate segments. Option D (12 meters): Incorrect. Phone operation is allowed on 12 meters in the appropriate segments.
Exam Tip
Phone prohibited = 30 meters only. Think '3'0 meters = '3'0-meter 'P'hone 'P'rohibition. Only band where phone (voice) is completely prohibited. All other listed bands allow phone in appropriate segments.
Memory Aid
Phone prohibited = 30 meters only. Think '3'0 meters = '3'0-meter 'P'hone 'P'rohibition. Only band where voice operation is completely prohibited. CW and digital modes only.
Real-World Example
You want to operate phone on 30 meters, but this is prohibited. The 30-meter band (10.100-10.150 MHz) is restricted to CW and digital modes only. You can use CW, RTTY, or other digital modes, but no SSB, AM, or FM voice. This is the only HF band with a complete phone prohibition.
