YAESU FTM-400DE - Radiotelefon przewoźny
C4FM FDMA / FM 144/430 MHz DUAL BAND TRANSCEIVER
 
The FTM-400DE is the first Mobile transceiver to be introduced that is fully compatible with Yaesu’s SystemFusion digital transmission system. The FTM-400DE 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 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.
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.
