FTM-400DE/XDE C4FM Dual Band 50W Digital/FM Mobile Transceiver
C4FM FDMA / FM 144/430 MHz DUAL BAND TRANSCEIVER
The FTM-400DE/XDE is the first Mobile transceiver to be introduced that is fully compatible with Yaesu's SystemFusion digital transmission system. The FTM-400DE/XDE has a large 3.5" touch sentivity colour screen. An advanced menu system provides easy access to over 100 seperate menu settings.
The FTM-400DE/XDE 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 diigital modulation schemes. C4FM is the standard method for professional communication devices in FDMA, and is therefore considered to be the main stream digital communication mode in the future.  Download our "Digital Communications Guide for Amateur Radio Operators" available on our web site that explains more about this efficient and reliable digital mode.
The three Digital and one Analogue modes are:
V/D Mode   (Voice/Data simultaneous communication mode)
The digital voice signal is transmitted in one half of the band width. Simultaneously the other half of the 12.5 kHz band width 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 mode
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.
FEATURES

Digital and Analog FM Capability
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.

Cross-band Capable
The FTM-400DE can operate Cross Band when in Analog mode; a very useful feature for emergency situations, etc.
GPS Included
Built-in GPS receiver and antenna provides location, time, direction and APRS® information. A GPS Logging Function is included. External GPS devices can be connected.
Hands-free Operation
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 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 which 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 back track 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 for each call sign on the screen. This useful function not only enables you to see which friends are within communication range, 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 valuable feature for public service group activites, Search & Rescue operations, and any number of other uses limited only by your imagination!
Smart Navigation Function
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.
Backtrack Function
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 valuable feature for RAYNET® Search & Rescue type operations as well as casual hiking and camping.
