Yaesu FTM-400XDR 2M/70CM C4FM FDMA / FM Transceiver
Yaesu FTM-400XDR 2M/70CM C4FM FDMA / FM Transceiver
The FTM-400DR is the first mobile introduced to be a fully compatable radio partner for use on the YAESU System Fusion Dual Mode system. Compared to other digital modulation schemes within FDMA, C4FM has excellent communication quality (BER: Bit Error Rate characteristics). 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 FTM-400DR operates in three (3) Digital modes and an (1) Analog mode 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.
• 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.

Digital and Analog FM Capable
The FTM-400DR performs flawlessly using both Analog FM and C4FM Digital. So there will be no loss of communications among friends who have not yet chosen to transition to Digital. Compact PackagingCase Size: Enjoy the easy of operation that
comes from the FTM-400 big 3.5-inch full color and its touch panel operation. The icon symbols, multi-function key
display and pop-up messages are all displayed in high-resolution color thanks to the full-color, high luminance TFT
liquid crystal screen. The settings and status of the wireless devices are displayed in an easy-to-understand
format. You can perform various operations simply and easily by gently touching the screen. Transmitter RF Power Output: 50 W / 20 W / 5 W. Modulation Type: F1D, F2D, F3E: Variable Reactance Modulation, F7W: 4FSK (C4FM) High Audio Output PowerLoud 3 Watt Audio Outputs with the internal speaker. 8 Watt output using Optional External Speaker (MLS-200-M10) Frequency Range
Receive 1200/9600bps APRS® (Automatic Packet Reporting System) Data communication capability included. Cross-band CapableThe FTM-400DR is cross-band capable when in Analog mode; a very important feature for emergency situations, etc. GPS IncludedBuilt-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 OperationLaw abiding (where required) 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.
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. 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. Optional Voice Guide Unit (FVS-2) announces your current operating frequency, band change and APRS® messages. You can record up to 5 minutes of received signals, or continuously record the last 30 seconds of received audio. Other Useful Features
- Real-time Band Scope with uninterrupted RX audio
