Digicom from Eartec is a new full duplex wireless that provides simultaneous talk communications. To operate the system simply turn the units “on” and talk through the headsets just like on a telephone. The digital transceivers are not voice-activated, and there are no buttons to push. A full line of headsets are available. No FCC license is required.Eartec Co., Narragansett, RI. www.eartec.com
