[Features] The RS-MS3I is an iPhone or iPad application designed to expand the DV mode capability of a D-STAR transceiver using a Terminal or an Access Point mode. These modes enable D-STAR operations by sending signals from the D-STAR transceiver over the Internet, even when that transceiver is out of the range of a D-STAR repeater. The transceiver sends your voice signals using an Internet, LTE, or 5G network, through an iPhone or iPad. 1. Terminal mode By operating the D-STAR transceiver through the iPhone or iPad, you can contact other D-STAR transceivers. In the Terminal mode, the transceiver will not transmit an RF signal, even if [PTT] is held down, because the microphone audio signal is transmitted through an Internet, LTE, or 5G network. 2. Access Point mode In this mode, the D-STAR transceiver functions as a Wireless LAN access point. The D-STAR transceiver repeats the received signal from the iPhone or iPad, to other D-STAR transceivers. Refer to the instruction manual (PDF) for setting details. The instruction manual can be downloaded from the ICOM website.
