I fly a sport plane that, technically, does not require a radio, but I much prefer to communicate with traffic at the airport, and the Icom radios connect directly into my stock communication system, allowing me to use the PTT button mounted on the yoke and the external antenna, as well as working with my headsets, including passing my own voice from the microphone to the headset, confirming clarity in the broadcast.

Very nice works as advertised

Radio works well with my two stroke engine.

It was a marvel of sensibility and simple design, pretty obviously a solid work of US engineering.

Radio works very well but the manual is close to useless.
