IC-756PRO 特點

最新款設計: 32-bit 浮點運算器的 DSP.  這款更新的 DSP 提供更佳的雜訊削除及自動 notch, 加上如下的特點

　

• AGC 自動增益迴圈運作 - IF 濾波器及 notch 迴路包含於 DSP 迴圈, 這將允許更寬廣的動態範圍

• 數位中頻 IF 濾波器 - 51 個可選擇的頻寬. 在於供給 PSK-31 及其它的數位模式, 這使得頻寬在 SSB 下的濾波器為 50Hz.

• 低失真, RF 方式壓縮器 - 發射頻寬是可選擇的: 2.0kHz, 2.6kHz, 及 2.9kHz.

• 內建 RTTY 解調器 demodulator / dual peak APF. -  內建 RTTY (baudot) 編解碼線路. 經由設定偏移寬度可選擇 2 個峰值頻率. 而無需外接 TNC 即可以抄收的字元顯示在顯示器之上.

• 麥克風等化器 - 一組總共  121 AF 特性可以選擇

• 手動 notch 功能 - 衰減: 70 dB

• 雜訊削除功能 - 可變動的階層設定

• TFT 5 inch color LCD - A first in HF transceivers! Provides a wider viewing angle and increased display of information. The following items are displayed on the LCD:

  • Dual frequency display

  • Memory frequency and memory name

  • IF filter bandwidth

  • RTTY tuning indicator / received character

  • Real-time spectrum scope

  • Voice memory / CW memory keyer contents

• 8 channel digital voice memory function - up to 15 seconds, 4 channels for transmit and 4 channels for receive

• Digital twin pass band tuning (PBT) - digitally narrows the passband width at the DSP to efficiently eliminate interfering signals. Operating the PBT at the DSP allows sharper, superior passband width characteristics for removal of unwanted signals.

• Real-time spectrum scope - selectable sweep range: ±12.5 kHz, ±25kHz, ±50kHz, ±100kHz

• Dual watch - the IC-756PRO can receive 2 signals on the same frequency band simultaneously. Conveniently monitor a DX station while operating on another frequency.

• Triple band stacking register

• Built-in memory keyer

• Built-in automatic antenna tuner - covers 50MHz

• Built-in Electronic keyer
