Dynamic microphones are relatively inexpensive and they are very durable. To wire a dynamic microphone to the 7300, you will need to connect the following wires: * The red wire from the microphone to the "MIC" input on the 7300. * The black wire from the microphone to the ground terminal on the 7300. ### Wiring a Condenser Microphone Condenser microphones are more sensitive than dynamic microphones and they offer a higher quality of sound. However, condenser microphones are also more expensive and they are more fragile. To wire a condenser microphone to the 7300, you will need to connect the following wires: * The red wire from the microphone to the "MIC" input on the 7300. * The black wire from the microphone to the ground terminal on the 7300. * The blue wire from the microphone to the "PTT" input on the 7300. The "PTT" input is used to activate the microphone when you are transmitting. When you press the "PTT" button on your microphone, the blue wire will be connected to the ground terminal on the 7300. This will tell the 7300 that you are transmitting and it will start sending your voice out over the airwaves. ### Testing Your Microphone Once you have wired your microphone to the 7300, you need to test it to make sure that it is working properly. To test your microphone, you can do the following: 1. Turn on the 7300 and set it to the receive mode. 2. Speak into the microphone and listen for your voice coming through the speaker on the 7300. 3. If you can hear your voice coming through the speaker, then your microphone is wired correctly and it is working properly. ### Conclusion Wiring a microphone to the Icom 7300 is a relatively simple task.
