Verified PurchaseQ: What is the side tone function on this adapter and how does it work? Also, is there any additional items that I will need for it to work?
A: The side tone function is a hardware feature that allows you to hear your own voice through your headset while you are transmitting on your radio. There is no external switch, software menu, or digital toggle to disable or enable it, it is always on.
Q: Without the separate PTT switch, can you transmit through your headset microphone using the transmit button on the handheld IC-A4?
A: Yes, it will work great in that scenario.
Q: Will this work with my a24 instead of a opc-499 ??
A: No, this will not work on the IC-A24. Instead you would need the Headset adapter for ICOM, A3, A22, A6, A24, and A14.
