*Question G2B03:
What is good amateur practice if propagation changes during a contact creating interference from other stations using the frequency?*  

*Correct Answer is  C: Attempt to resolve the interference problem with the other stations in a mutually acceptable manner*  

### AI Response: (may contain errors)  

In amateur radio, good operating practice is essential, especially when dealing with interference. Let's break down the correct answer and why the other choices are not appropriate:

1. **Correct Answer: C - Attempt to resolve the interference problem with the other stations in a mutually acceptable manner**

   - **Explanation**: Amateur radio is a shared resource, and operators are encouraged to cooperate and communicate effectively. If propagation changes cause interference, the best practice is to engage with the other stations to find a solution that works for everyone. This might involve negotiating a frequency change or adjusting operating times. The goal is to maintain harmony and ensure that all operators can enjoy the hobby.

2. **Why the Other Choices are Incorrect**:

   - **A: Advise the interfering stations that you are on the frequency and that you have priority**
     - **Explanation**: No station inherently has priority over others on a frequency. Amateur radio operates on a non-interference basis, meaning all operators should work together to resolve issues without asserting dominance.

   - **B: Decrease power and continue to transmit**
     - **Explanation**: While reducing power might lessen interference, it does not address the root of the problem or involve the other stations in finding a solution. It might also make your signal too weak to maintain effective communication.

   - **D: Switch to the opposite sideband**
     - **Explanation**: Changing sidebands might not resolve the interference if the other stations are using the same mode. Additionally, this action does not involve communication with the other stations to find a mutually agreeable solution.

In summary, the key to resolving interference is cooperation and communication, which is why option C is the best choice.
