The KENWOOD TH-D75A is a feature-rich 144/220/430 MHz triband transceiver that brings advanced APRS® and D-STAR® digital voice capabilities together in one powerful handheld.
Designed for amateur operators who want more ways to connect, it supports real-time GPS tracking, messaging, and wideband reception across multiple modes, from FM and D-STAR to SSB and CW. With its rugged design, built-in GPS, Bluetooth® connectivity, and seamless PC integration, the TH-D75A delivers unmatched versatility for local contacts, satellite communications, or global QSOs, all with KENWOOD’s legendary audio clarity and intuitive operation.
Compatible with the APRS communication protocol, which allows real-time two-way data transmission by using packet communications. Various types of communication are possible, such as GPS positional information sharing, text messaging, and communicating via the ISS and other satellites. In addition, full-fledged APRS operation is made possible through a unique standalone digipeater function that sets APRS-veteran KENWOOD apart.
The TH-D75A is capable with a relative direction display that enables you to see at a glance real-time GPS information or pre-set information for your own station, and the distance/direction/heading/speed of other stations. It is now easier to recognize any position and heading relationships with your own station. Weather station information can be displayed in color for rainfall, temperature, wind direction/speed, barometric pressure, and humidity data.
A maximum of 100 stations can be stored, including mobile stations, base stations, weather stations and objects. You can also limit and sort the types of stations you receive. Local information can also be transmitted as an "object."
FM or D-STAR voice channels can be set according to frequencies or D-STAR repeater information embedded in beacons from APRS stations, enabling fast QSY.
Real-time messaging between stations running APRS is possible. Messages to be sent can be input using the keys or selected from a number of templates.
The TH-D75A is capable of operating as a standalone digipeater station. It can be configured as a temporary relay station in a variety of scenarios, such as outdoors, enabling for support data communications from locations such as basins surrounded by mountains.
The built-in KISS mode TNC for APRS enables APRS operation via PC after connection via USB or Bluetooth.
The TH-D75A is also compatible with a variety of features that expand its scope of operation, including SmartBeaconing, decay algorithm, proportional pathing and APRS voice.
Supports D-STAR, the amateur radio digital communications protocol, which provides both voice and data modes. From local to overseas QSOs can be enjoyed in a variety of modes, including simplex, single repeater, and gateway communications over a network of repeaters. Newly supported Reflector Terminal mode and simultaneous reception of two digital voice signals provide additional flexibility to D-STAR operations.
The TH-D75A is compatible with the D-STAR amateur radio digital communication protocol promoted by the Japan Amateur Radio League (JARL). Users can enjoy easy voice and data communication locally or with the world.
The TH-D75A features a DV fast data mode that accelerates communication throughput by sending data on unused voice frames for more comfortable data communication.
A maximum of 100 stations can be stored, including mobile stations, base stations, weather stations and objects. You can also limit and sort the types of stations you receive. Local information can also be transmitted as an "object."
The unit employs a separate menu for D-STAR and its many modes, such as switching between simplex (DV) and repeater (DR), or voice and data, enabling operation switching with a single touch.
Built-in MMDVM serial commands offer easy access to D-STAR reflectors via a Windows PC or Android device with a third-party application through USB or Bluetooth, with no need for a mini-RF device such as a Hotspot.
Simultaneous reception of any two channels in D-STAR (DV/DR) and Reflector Terminal mode is possible. This enables operating in DR while watching a call channel in DV. Furthermore, the range for digital mode use is greatly expanded and includes options such as watching a D-STAR repeater while operating in Reflector Terminal mode.and data, enabling operation switching with a single touch.
The latest repeater list can be downloaded from the KENWOOD website. Updates to the latest information can be made from a PC via USB cable, Bluetooth, or microSD card.
The high-performance GPS module with patch antenna provides positional information for APRS/D-STAR operation, along with GPS tracklog and automatic time correction.
The unit features a USB Type-CTM port for data communication with PCs. And also for charging its genuine lithium-ion battery. Bluetooth (HSP, SPP) and microSD/SDHC memory cards are also supported.
The 770+ audio prompts inform you of operating status, such as menus, parameters, frequency or memory channel contents displayed on the screen, including support for reading callsigns with phonetic codes. Voice guidance speed can be set to one of 4 levels.
Wideband reception is possible on Band B. In addition to DV/DV fast data/FM/NFM/WFM/AM on the 0.1~524MHz band, SSB/CW reception is also possible. The TH-D75A has a fine mode that achieves zeroing-in with a minimum step frequency of 20Hz*1, and is equipped with a bar antenna*2 for 0.1~10MHz reception. A built-in IF receiving filter reduces neighboring interference signals during SSB or CW reception, realizing low-interference and unprecedented comfortable reception. It also is equipped with two-wave simultaneous receive functionality for VxV, UxU and VxU.
*1: Only for SSB, CW and AM modes
*2: Selectable with SMA antenna connector
An IF signal with a central frequency of 12kHz and a bandwidth of 15kHz can be output via the USB port. Smart operation via a PC is possible, such as by using the PC's band scope* to check the status of nearby frequencies while monitoring received SSB, CW, and AM sound.
KENWOOD'S custom tuning, which has a reputation for sound quality, makes for clear voice communications that are easy to hear. The TH-D75A also comes equipped with a DSP-based audio equalizer that enables the setting of each of a 5-band reception EQ (0.4~6.4kHz) and 4-band transmission EQ (0.4~3.2kHz), making sound quality adjustable to your preference.
