Enjoy D-STAR Communication More Actively and More Comfortably

Terminal Mode and Access Point Mode Expand Communication Coverage and Fun

Terminal and Access Point modes* enable you to enjoy long-distance D-STAR (Digital Smart Technology for Amateur Radio) communication through the Internet. You can access the D-STAR repeater network through the Internet, regardless of locations and conditions of nearby repeaters.

* An optional free download software, RS-MS3W is required to be installed in the PC. An optional free download application, RS-MS3A is required to be installed, in the Android™ device.

DR (D-STAR Repeater) Function

The DR function makes D-STAR communications simple. By simply selecting a destination call sign in "To", and your access repeater in "From", you can talk with other D-STAR users. In addition, using the reflector function, you can talk through several repeaters at once.

Easy-to-Read Full Dot-Matrix Display

To increase the amount of display information, a full dot-matrix display is used in the ID-4100A. For example, Repeater list or GPS position information are clearly arranged and easy to read.

DV/FM Near Repeater Search Function

The DV/FM near repeater search function assists you in accessing nearby repeaters, even in areas you are visiting for the first time. The function searches for nearby repeaters using the repeater memories with the GPS position information.

* To use the near repeater search function, the position data of the repeater is required. The ID-4100A will be shipped with the D-STAR repeater memories preprogrammed, but the position data of some D-STAR repeaters may not be entered or exact.

Applications for iOS™ and Android™ devices*

The RS-MS1I (for iOS™ devices) and RS-MS1A (for Android™ devices) enable you to wirelessly connect to the ID-4100A and remotely set the DR functions, link with a map application and send/receive messages over the DV mode. In addition, pictures taken by a smart device can be transmitted via the DV Fast Data mode or DV mode.

* The optional UT-137 Bluetooth® unit must be installed in the ID-4100A. Some functions may not work properly, depending on smart devices used.
