VHF/UHF DIGITAL TRANSCEIVER MULTI-PROTOCOL DIGITAL AND ANALOG MOBILE RADIOS

Model: NX-3720HG/3820HG

This adaptable mobile radio supports both NXDN and DMR digital protocols as well as mixed digital   FM analog operation, enabling it to serve with distinction in a wide range of enterprise- and operation-critical applications. 


The NX-3000 Series offers unsurpassed interoperability for a wide variety of users as it supports muluti digital CAIs — NXDN and DMR — plus FM analog in a single radio. Best of all, a desired CAI can be selected at will, giving you the freedom to migrate at your own pace — whether you are intent on going fully digital, undecided about which digital system to pick, or just wanting to maintain both digital and analog for a while. An NX-3000 radio can simultaneously support two digital protocols plus analog, offering the following combinations: FM/NXDN and FM/DMR.
