YAESU FTM-400DE / XDE C4FM Dual Band 50W Digital/FM Mobile 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.
