*Question E1C03:
[97.303(g)] How long must an operator wait after filing a notification with the Utilities Technology Council (UTC) before operating on the 2200-meter or 630-meter band?*  

*Correct Answer is  B: Operators may operate after 30 days, providing they have not been told that their station is within 1 kilometer of PLC systems using those frequencies*  

### AI Response: (may contain errors)  

To operate on the 2200-meter or 630-meter amateur radio bands, operators must follow specific notification procedures due to the potential for interference with Power Line Carrier (PLC) systems. Here's a breakdown of the correct answer and why the other choices are incorrect:

1. **Correct Answer: B**  
   Operators may operate after 30 days, providing they have not been told that their station is within 1 kilometer of PLC systems using those frequencies.  
   - **Explanation**: The FCC requires amateur operators to notify the Utilities Technology Council (UTC) before operating on these bands. If the UTC does not inform the operator of any potential interference issues within 30 days, the operator can begin transmitting. This rule helps ensure that amateur operations do not interfere with existing PLC systems.

2. **Why the Other Choices are Incorrect**:
   - **Choice A**: "Operators must not operate until approval is received"  
     - This is incorrect because explicit approval is not required. The operator can proceed after 30 days if no interference issues are reported.
   - **Choice C**: "Operators may not operate until a test signal has been transmitted in coordination with the local power company"  
     - This is incorrect because there is no requirement for a test signal or coordination with the local power company. The notification to the UTC is the only requirement.
   - **Choice D**: "Operations may commence immediately, and may continue unless interference is reported by the UTC"  
     - This is incorrect because operators must wait 30 days after filing the notification before commencing operations, not start immediately.

**Rule of Thumb**:  
- **Notification Period**: Wait 30 days after notifying the UTC before operating on the 2200-meter or 630-meter bands, unless informed of potential interference within 1 kilometer of PLC systems.
