H10 - FT-897D Desktop Allmode Transceiver HF/VHF/UHF Yaesu
FT- 897D on vastupidav , uuenduslik, mitme lainealaga , mitmerežiimne kaasaskantav raadiosaatja amatöörraadio MF/ HF /VHF /UHF lainealadele. Pakkudes katvust 160-10 meetri sagedusalades pluss 6 m , 2 m ja 70 cm sagedusalades FT -897 võimaldab töötamist SSB , CW, AM , FM ja digitaalsed režiimid , ja see on võimeline 20 W kaasaskantavaks kasutamiseks sisemise akuga või kuni 100 W , kui kasutatakse välise 13,8 volti alalisvoolu toiteallikat. The
new FT-897D version includes the 0.5 ppm TCXO Unit, at no additional
charge!
Põhiomadused Battery-Powered Field Operation The
bottom side of the FT-897 contains a “power source tray” which
can accommodate up to two of the optional 13.2 Volt, 4500 mAh FNB-78
Ni-MH Battery Packs, for completely portable operation without any
external power source. Maximum power output is 20 Watts (all bands)
during battery operation, and with two FNB-78s you may expect up to
eight hours of operating time (TX 5%, RX 5%, standby 90%). What’s
more, you can charge one of the FNB-78 Battery Packs while operating
the FT-897 off the other pack—ideal for situations where solar or
other power sources are available. The optional CD-24 Charge Adapter
provides the necessary voltage for charging, and it may be used in
conjunction with an external 13.8 Volt source, or the optional PA-26
AC Adapter may be used to power the CD-24. DC
13.8V Mobile Operation Mobile
operation, using the FT-897 as the cornerstone, is pure joy! The
combination of the FT-897 and the ATAS-120 Auto-Tune Antenna System
provides automated operation from HF through the UHF spectrum! Using
an external 13.8 Volt power source, you get a full 100 Watts of power
output on HF and six meters (144 MHz: 50 W, 430 MHz: 20 W). Base
Station Operation The
FT-897’s outstanding fundamental performance invites expansion into
a full-featured base station. The optional FP-30 Internal Power
Supply provides operation from AC sources, and the clamp-on FC-30
Automatic Antenna Tuner option expands the impedance range of the
transceiver. Round out your station with the MD-200A8X Deluxe Desk
Microphone and the VL-1000 Quadra System Linear Amplifier for
world-class performance at home! The power source tray of the FT-897
is designed to accommodate the optional CE approved FP-30 Internal
Power Supply, allowing full-power operation from 200-240 V AC power
source. The quiet switching-regulator design of the FP-30 is tolerant
of AC input voltage variations, making it ideal for DX-pedition use!
And to extend the impedance bandwidth of your antenna system, the
innovative FC-30 Automatic Antenna Tuner option clamps onto the left
side of the FT-897 in seconds!Rugged,
High-Output Power Amplifier Achieving
100 Watts of power output from such a compact package is a difficult
mechanical and electrical engineering task. On HF, push-pull 2SC5125
Bipolar transistors driven by push-pull 2SK2975s provide the 100-Watt
power capability, while on VHF maximum efficiency during battery
operation is yielded by 2SC3102 bipolar PA transistors. The rugged
aluminum die-cast chassis provides a solid foundation for the heat
sink for the power amplifier, with a total of almost 40 cubic inches
of heat sink surface area available. With its
thermostatically-controlled twin cooling fans, the FT-897 will stand
up to the rigors of DX-pedition or home contest use, with dissipation
capability to spare! Built-in
Digital Signal Processing The
FT-897 includes a wide array of analog and DSP filters to help you
dig out those weak DX signals on a crowded band! One-touch activation
of the DSP filters, plus a convenient “DSP” LED on the front
panel, enhance the ease of using the DSP. DSP Bandpass Filters, Noise
Reduction,a nd Auto-Notch Filter circuits are included. Outstanding
Features for the CW Expert A
wide array of features are tailored to the CW enthusiast operating
from home or on an expedition! Included are a CW Tuning indicator, CW
Pitch control, Electronic Keyer with three memories and Weight
Control, and selection of Full QSK or “Semi-break-in” operation.
For DX-pedition use, a unique “Beacon” mode allows you to send a
repetitive message on, for example, six meters, to help others spot
propagation to your location. And if you’re looking to upgrade your
license class, the CW Trainer feature will send five-character
letters and/or numbers via the speaker, so you can practice CW
reception when the bands are dead!
