Rockwell-Collins Model: KWM-380 HF-380 HF帯 ゼネラルカバレッジ トランシーバー: 1979 年 9 月発表: Scope: KWM-380 HF-380: 回路はオールソリッドステート化。受信部は、高周波増幅回路が無く、直接 DBM で周波数変換、第一中間周波数 39.145MHz, 第二中間周波数は 455KHz、局発( 6.71MHz +- 2.85KHz ) との間で 6.25MHz を得て、可変 PassBand Tuning をしている。当時としては画期的な Up-Coversion method を採用。 ファイナルは Motorola 社の MRF421 をプッシュプルで採用、出力 100 watts を得ている。局発は PLL 回路方式採用、バンド 切替スイッチは無く、 MHz - KHz - 100Hz - 10Hz の四つのスイッチで選択して周波数を設定。 主な仕様: 受信周波数: 500KHz - 30MHz 送信周波数: 1.6MHz - 30MHz (= KWM-380 はハムバンドのみ) < 10Hz step > < 500KHz - 1.4MHz は受信感度 30dB attenuated > 寸法: 394mm (W) x 165mm (H) x 457mm (D) 重量: 21.8 Kgs (48lbs) 電源: 105 - 115 - 125 - 210 - 220- 230 - 240 - 250V AC or 12 - 15V DC 受信モード: USB LSB AM and CW 送信モード: USB LSB CW 感度: 0.5μV or better for 10dB (s+n) for 2.0MHz - 30.0MHz 感度: 1.0μV or better for 10dB (s+n) for 1.8 - 2.0MHz 選択度: 3-dB minimum: 8KHz 2.1KHz Optional Filters: 6KHz AM (特に昨今のノイズの多い時代、快適な BCL を保証)。 3KHz SSB (表示は 2.8KHz) 素晴らしい音です ! 1.7KHz RTTY 500Hz CW 360Hz CW 200Hz CW 140Hz CW IF and Image Rejection: Greater than 60dB 送信出力: 100 watts pep, nominal. 不要輻射: Carrier: -50dB or better. 不要サイドバンド: 1KHz ref. -55dB 高調波: -40dB or better. 第三次歪: 25dB below. デジタルシンセサイザー精度: Plus or Minus 5Hz 以内。 (通電後 10 分) その他主な Options: 冷却ブロアーキット。 Speech Processor。 Noise Blanker。 Kiron Memory Board。 |
