20191020 今天傍晚趁著有空的時候,帶著YAESU FT-891及ATAS-120和HK-704跟汽車電池,前往住家附近的山上進行YAESU FT-891的初次操作及CW QSO測試!
FT-891對我來說算是比較新一點的機器,雖然功能蠻多的,但對我來說,YASEU的HF車機我並不陌生,所以很容易就上手!
這部機器是2016年底生產的,但是最近幾年的新機器,出廠後都陸續會有新的FIRMWARE可以更新,經查YAESU網站最新FIRMWARE是2017,
所以她的FIRMWARE必須更新至2017.
FIRMWARE更新部分包括MAIN/DSP/LCD(PANEL)3部分,要使用YFWS032更新軟體及安裝YAESU USB 驅動程式!
詳細更新方式可參考YAESU網站!
FT-891 / HK-704
經過FIRMWARE更新後的FT-891,所有的頻率顯示會多出5MHz選項,經過簡單的CW MODE設定後開始工作,設定過程還算很順利,連接ATAS-120切換到各個不同頻率,7/10/14/18/21/24/28/50MHz,按下"TNR鍵"自動調階都很順利,而且她還可以手動做ATAS-120的微調調階,當選擇頻率的SWR過高時,可以上下頻率做微調調階,真的是很不錯的功能,不會像連接以前的FT-100D,若遇到SWR過高的時候,只會顯示SWR過高,除了重新調階外,無法手動做上下頻率微調調階的動作,不過畢竟FT-100D是20幾年前的產品,是不能與現代新設計的機器相提並論!畢竟以當時的年代,YAESU FT-100D也算是移動車載的一代銘機!
FT-891操作按鍵紐
覺得FT-891的接收系統是非常棒的,當開啟NAR及DNR鎖定頻率的時候,訊號變得非常乾淨,不輸座台機!
CW MODE JA1GZV/MOTO SAN
FT-891搭配ATAS-120也算是移動通訊非常方便的一套設備.
FT-891對ATAS-120除了自動調階控制外,還可以進行手動微調調階,非常不錯的功能!
只開啟NAR未開啟DNR的接收情況,CW MODE HL07NWPF
覺得FT-891的CP值是非常高的一部車機,她的功能相當多不輸座台機,是一部非常不錯的HF/50MHz移動車載機器!
她的功能及配備無法一一介紹,僅能在CW這一部分簡單操作介紹!
給大家參考!

Uncompromising Receiver Circuit Design Ensures Excellent Performance
• Triple conversion with a 1st IF frequency of 69.450 MHz (SSB/CW/AMStable 100 Watt Output The FT-891 provides stable 100 Watts (25W AM) of high power output. High reliability is assured by the transmitters careful circuit design with efficient thermostatically-controlled Dual internal fans and the die cast heat transferring chassis.32-Bit IF DSP Provides effective and optimized QRM rejection The 32 bit high speed floating Point DSP (max 3000 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently frustrating while on the HF bands. The highly optimized AUTO NOTCH (DNF) automatically eliminates dominant beat tones, and the CONTOUR, and the APF, are very effective receiver noise reduction tools during HF band operations.USB Connection A native USB connection supports PC connectivity with a single cable, allowing for full rig control via a virtual serial port connection (VCP).Features for Ease of Operation • Large diameter Main Tuning Dial (1.6” / 41mm) with Torque adjustmentSupport for ATAS (Active Tuning Antenna System) The FT-891 fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System (optional) allowing for plug and play field and mobile operation.Ultra compact design Measuring 6.1” x 2.0” x 8.6” (155 x 52 x 218 mm), The FT-891 is an innovative Multi-band, Multi-mode Mobile/Portable transceiver with an Ultra Compact and rugged case design.Optional FC-50 Antenna Tuner Unit The FC-50 is a microprocessor-controlled antenna tuner that is designed specifically for the FT-891. The FC-50 can be easily coupled with the FT-891 and includes all necessary interconnect cables for operation right out of the box.Specifications Specifications |
