D-STAR (Digital Smart Technologies for Amateur Radio) configuration types.
D-STAR is a digital voice and data protocol for amateur radio developed by JARL (Japan Amateur Radio League). The TH-D75 supports DV (Digital Voice) mode with features including reflector linking, callsign routing, gateway access, and DR (D-STAR Repeater) mode for simplified operation.
§Callsign registration (per Operating Tips §4.1.1)
Before using D-STAR gateway/reflector functions, the operator’s callsign must be registered at https://regist.dstargateway.org.
§My Callsign (per Operating Tips §4.1.2)
A valid MY callsign is required for any DV or DR mode transmission. Menu No. 610 allows registration of up to 6 callsigns; the active one is selected for transmission.
§DR mode (per Operating Tips §4.2)
DR (Digital Repeater) mode simplifies D-STAR operation by combining repeater and destination selection into a single interface. The operator selects an access repeater from the repeater list and a destination (another repeater, callsign, or reflector), and the radio automatically configures RPT1, RPT2, and UR callsign fields.
§Reflector Terminal Mode (per Operating Tips §4.4)
The TH-D75 supports Reflector Terminal Mode, which connects to D-STAR
reflectors without a physical hotspot. On Android, use BlueDV Connect
via Bluetooth; on Windows, use BlueDV via Bluetooth or USB.
§Simultaneous reception
The TH-D75 can receive D-STAR DV signals on both Band A and Band B simultaneously.
§Repeater and Hotspot lists (per Operating Tips §4.3)
The radio stores up to 1500 repeater list entries and 30 hotspot list entries. These are managed via the MCP-D75 software or SD card import.
These types model every D-STAR setting accessible through the TH-D75’s menu system (Chapter 16 of the user manual) and MCP programming memory (pages 0x02A1+ in the memory map, plus system settings at 0x03F0).
