Icom M36

The M36 is a full 6 watt waterproof radio that floats!
Clear voice plus voice boost
In marine environments there are many sources of noise that can affect the quality of your communications, such as engine noise, breaking surf and more. The IC-M36 automatically adjusts the outgoing voice and the incoming audio to compensate for the ambient noise level: whether you're in a loud environment or in a quiet area, the IC-M36 ensures your radio conversation is sent and received as clearly as possible.
LOUD button
When you need an instant "boost" in the volume, a simple push of the "LOUD" button gives you full volume immediately. In addition, holding the "LOUD" button mutes the audio output.
Noise cancelling microphone
The sub-microphone on the rear panel inverts phase and cancels out ambient noise from the main microphone. As a result, the IC-M36 reduces the affect of background noise (particularly trebly noise) from the transmitted signal and makes it easier to catch voice communication.
Low power consumption
Although the IC-M36 delivers a high 6W RF output and 700mW audio output, its current saving circuit offers a practical 8 hours (approx) of operating time with the supplied 980mAh Lithium-Ion battery pack.
