*Question E1A06:
[97.303(h)(1)] What is the required transmit frequency of a CW signal for channelized 60 meter operation?*  

*Correct Answer is  B: At the center frequency of the channel*  

### AI Response: (may contain errors)  

To understand the required transmit frequency of a CW signal for channelized 60 meter operation, we need to look at the definition of channelized operation and the characteristics of CW (Continuous Wave) signals.

### Correct Answer: At the center frequency of the channel

- **Explanation**: In channelized operation, the frequency of the transmitted signal must be centered within the designated channel. This ensures that the signal occupies the correct bandwidth and minimizes interference with adjacent channels. For CW signals, which are typically narrowband, transmitting at the center frequency allows the signal's sidebands to remain within the allocated channel limits.

### Why the Other Choices are Incorrect:

- **A: At the lowest frequency of the channel**  
  - This is incorrect because transmitting at the lowest frequency could cause the signal's sidebands to extend outside the channel, potentially interfering with adjacent channels.

- **B: At the center frequency of the channel**  
  - This is actually the correct answer, as explained above.

- **C: At the highest frequency of the channel**  
  - Similar to option A, transmitting at the highest frequency could also result in the signal's sidebands extending beyond the channel limits, leading to interference.

- **D: On any frequency where the signal’s sidebands are within the channel**  
  - While this might seem reasonable, it is not specific enough for channelized operation. The requirement is to transmit at the center frequency to ensure compliance with regulations and to maintain proper channel spacing.

### Summary

For channelized 60 meter operation, always transmit at the center frequency of the channel to ensure compliance and minimize interference. This is a key rule for operating within the amateur radio bands effectively.
