*Question E2D10:
What does the packet path WIDE3-1 designate?*  

*Correct Answer is  C: Three digipeater hops are requested with one remaining*  

### AI Response: (may contain errors)  

The packet path WIDE3-1 is part of the AX.25 protocol used in amateur radio packet communications. Here's a breakdown of the correct answer and why the other choices are incorrect:

### Correct Answer: C - Three digipeater hops are requested with one remaining

- **Explanation**: 
  - The designation "WIDE3-1" indicates that the packet is allowed to be digipeated (repeated by digipeaters) up to three times. The "3" signifies the maximum number of hops, while the "-1" indicates that one hop has already been used. Therefore, there are two hops remaining for the packet to reach its destination.

### Why the Other Choices are Incorrect:

- **A: Three stations are allowed on frequency, one transmitting at a time**  
  - This choice is incorrect because WIDE3-1 does not refer to the number of stations allowed on a frequency. Instead, it specifically relates to the number of digipeater hops.

- **B: Three subcarriers are permitted, subcarrier one is being used**  
  - This choice is incorrect as it misinterprets the terminology. WIDE3-1 does not involve subcarriers; it pertains to the number of hops in a digipeating path.

- **D: Three internet gateway stations may receive one transmission**  
  - This choice is incorrect because WIDE3-1 does not refer to internet gateways. It is strictly about the number of digipeater hops in the packet path.

### Summary

- **WIDE3-1** indicates a maximum of three digipeater hops, with one already used, leaving two remaining.
- Understanding packet paths is crucial for effective communication in amateur radio, especially in packet radio operations.
