Extend D-STAR coverage

The new Terminal mode and Access point mode enable you to make D-STAR calls through the Internet, even from areas where no D-STAR repeater is accessible.
  • Terminal mode - Connect the ID-51A PLUS2 to the Internet through a PC or Android® device, and send your voice and/or data through the Internet gateway to a destination repeater.
  • Access point mode - Use an ID-51A PLUS2 radio connected to the Internet through a PC or Android® device, as an Access point. You can use another D-STAR radio to send your voice and/or data through the Access point radio, and communicate with D-STAR stations all over the world.

RS-MS1A, Free Download Android™ Application

The RS-MS1A allows you to connect your Android™ device to the ID-51A*. You can see the location of repeater sites on a map application and set them to the ID-51A. Text messages and pictures can be sent and received with your Android™ device.

*The OPC-2350LU data cable is required to connect to an Android™ device.

RS-MS1A Features

  • Send and receive pictures
  • Send and receive text messaging
  • Set transceiver’s DR functions from the RS-MS1A or a map application
  • See the location of repeater sites or other D-PRS stations on a map application
  • View and export received history of the transceiver
  • View detailed data in the transceiver’s Repeater list
  • Import and export the Repeater list and the Callsign list from/to the transceiver

DV Fast Data Mode*

By using data in place of voice frames, the ID-51A transfers data 3.5 times faster (3480 bps) than in the conventional DV mode (with voice). Pictures taken by an Android™ device can be quickly transmitted in the DV Fast Data mode.
*The DV Fast Data mode is not compatible with the DV mode low-speed data communication.

DV and FM Repeater Search Function

The repeater search function searches for nearby analog FM repeaters as well as DV repeaters using the repeater memories and the integrated GPS*.
*To use the repeater search function, the position data of the repeater is required.
