Question E1F10:
[97.201] Who may be the control operator of an auxiliary station?  

Choices:  
A: Any licensed amateur operator  
B: Only Technician, General, Advanced, or Amateur Extra class operators  
C: Only General, Advanced, or Amateur Extra class operators  
D: Only Amateur Extra class operators    

Correct Answer is  B: Only Technician, General, Advanced, or Amateur Extra class operators  

Correct answer: B — Only Technician, General, Advanced, or Amateur Extra class operators.

1) Why B is correct
- Per 47 CFR §97.201(b), the control operator of an auxiliary station must hold at least a Technician Class license. That includes Technician, General, Advanced, and Amateur Extra.

2) Why the other choices are incorrect
- A: “Any licensed amateur operator” is incorrect because it would include Novice, which is not permitted to control an auxiliary station.
- C: Excludes Technicians, but Technicians are explicitly allowed.
- D: Far too restrictive; you don’t need to be Extra to control an auxiliary station.

3) Useful rules of thumb
- Auxiliary station = point-to-point links within a system of cooperating amateur stations (often repeater links or remote base control).
- Control operator class for auxiliary: Technician or higher.
- Frequency note: Auxiliary stations may transmit on frequencies above $222.15\ \text{MHz}$ (subject to band-specific restrictions).
