Update

After being contacted by Icom America and being asked to remove certain content on this site, I have removed the software, firmware, and service manual downloads from the site. Icom is treating this information as proprietary, and I respect their position.

NXDN Information

This site is a source of information about the Icom and Kenwood digital voice technology branded as NXDN.

Due to my familiarity of Icom products, this site contains predominantly Icom information.

Please be aware that virtually everything here is the property of Icom, Kenwood, or both of them. This site is in no way affiliated with Icom Corporation or Kenwood Corporation.
