The FTM-400XDE is the first Mobile transceiver to be introduced that is fully compatible with Yaesu System Fusion digital transmission system. The FTM-400XDE has a large 3.5" touch-sensitive color screen. An advanced menu system provides easy access to over 100 separate menu settings.
The FTM-400XDE operates in three Digital modes ( Voice and Data, Voice Full Rate, and Data Full Rate) and in one Analog mode (NBFM) to suit your needs. This feature-packed radio is our first Digital Mobile equipped with our new Automatic Mode Select (AMS) function that instantly detects the received signal mode. The AMS function enables stress-free operation and eliminates the need to manually switch between communication modes. The FTM-400XDE is identical to the FTM-400DE except for an updated internal GPS unit. C4FM has an excellent communication quality with lower BER characteristics compared to other FDMA digital modulation schemes. C4FM is the standard method for professional communication devices in FDMA and is therefore considered to be the mainstream digital communication mode in the future. Download our "Digital Communications Guide for Amateur Radio Operators" available on our website that explains more about this efficient and reliable digital mode.
The three Digital and one Analogue mode are: V/D Mode (Voice/Data simultaneous communication mode)
The digital voice signal is transmitted in one-half of the bandwidth. Simultaneously the other half of the 12.5 kHz bandwidth channel is used for error correction of the voice signal and other data. By incorporating powerful error correction technology developed for professional communication devices, effective error correction codes provide the advantage of fewer interruptions to conversations. The Clear Voice technology developed for the C4FM FDMA Digital mode provides the ideal balance of error correction and sound quality. Voice FR mode (Voice Full Rate Mode)
This mode uses the full 12.5 kHz bandwidth to transmit digital voice data. The increased amount of voice data permits high-quality voice communication, providing superb sound quality for a “rag chew” with friends.
Data FR mode (High-Speed Data Communication Mode)
This high-speed data communication mode uses the full 12.5 kHz bandwidth for data communication. The transceiver automatically switches to Data FR mode when transmitting snapshot pictures, and can be used to transmit large quantities of data at high speed. Analog FM is effective when weak signal strength causes audio drop out in the digital mode and enables communication up to the borderline of the noise level. Also, the use of established Yaesu low power circuit designs provides greater efficiency than the digital modes. This is the typical FM mode used by most typical non-digital handhelds and VHF/UHF mobiles.
There is no loss of communications with other hams who have not yet chosen to add Digital Communications to their stations. The FTM-400DE performs perfectly well using both Analog FM and C4FM Digital.

The FTM-400DE can operate Cross Band when in Analog mode; a very useful feature for emergency situations, etc.
The built-in GPS receiver and antenna provide the location, time, direction, and APRS® information. A GPS Logging Function is included. External GPS devices can be connected.
Hands-free operation is available by using the optional wireless Bluetooth® unit and headset. Optional Bluetooth® unit (BU-2) and Headset (BH-2A) are required.
Snapshot Function (Image Data Transmission)
Simply connect an MH-85A11U (option) microphone with a camera. Press the microphone shutter button to take snapshots, and then the image data can be displayed on the screen, and easily sent to other C4FM FDMA digital transceivers.
Image data that was sent from a group member is displayed on the full-color screen. This image data also retains a time record and the GPS location data of the snapshot. It is easy to navigate to that pictured location by using the backtrack function. In addition, you can observe on the screen, whether or not transmitted data was successfully received by the member station. The snapshot image or received data is stored in a high-capacity micro SD card. You can recall and send that image data from the SD card anytime. The pictures and data files may be easily viewed and edited by using a personal computer.
* Micro SD card (not included) is required for the Snapshot function
Digital Group Monitor (GM) Function
The digital GM function automatically checks whether members registered to a group are within the communication range, and displays information such as the distance and orientation of each call sign on the screen. This useful function not only enables you to see which friends are within communication range, but it also permits you to see at a glance where all group members are located. Additionally, this function can be used to send messages and image data between group members. The Digital Group Monitor applies to direct communications between members; it is not applicable through a repeater.
This is a valuable feature for public service group activities, Search & Rescue operations, and any number of other uses limited only by your imagination!
Smart Navigation Function
The real-time navigation function enables location checking at any time. In digital V/D mode, information such as position data is transmitted together with voice signals so the distance and direction to the other stations can be displayed in real-time while communicating with them.
The Backtrack Function enables navigation to a registered location at the touch of a button. When hiking or camping, simply register your starting point or campsite before departure, and the distance and orientation from the current location are displayed on the screen.
This is a valuable feature for RAYNET® Search & Rescue type operations as well as casual hiking and camping.
Voice Guide and Recording Function
