八重洲無線 FTDX3000 の概要です。
US版カタログ(web)から抜粋。
主な特徴
1.8～54MHz 100W機
9MHzの1st IFにクリスタルルーフィングフィルタを採用してFTDX5000並みの受信性能。
2nd IFは30KHz(24KHzFM/AM)
3.5inch wideサイズ カラーLCD display採用
スペクトラムスコープ内蔵
9MHz IF-OUT （→ SDRとか繋げますね！)
RTTY/PSKエンコーダー/デコーダー(オプション)でディスプレイに表示可能
（DMU-2000にアップデートでこの機能は付かないの？)
50MHz用受信アンプ内蔵
USBインターフェース
カタログ表記でもフロントパネル写真を見ても、サブ受信機は内蔵していないようですが？
FTDX----なのに100W機。
サイズは365x115x312mm(10kg)ということでかなりコンパクトに収まっているようです。
