YAESU FL 7000

  • Yaesu FL-7000 HF Linear Amplifier,The FL-7000 is a microprocessor-controlled, all solid state linear amplifier with built in power supply and automatic antenna tuner, providing up to 1.2 kilowatts RF input power on the 160- through 10- metre HF ham radio bands, including the WARC bands. Super fast T/R turnaround timing allows the FL-7000 to be used for QSK CW, HF packet radio and even AMTOR with an exciter so designed. Requiring only 70 watts of excitation for full output, four transistors with 300W collector dissipation each are combined in a full y protected push-pull parallel wideband ?no-tune? amplifier circuit, powered by a heavy duty regulated 47V, 25A DC power supply and cooled by a bottom mounted fan through Yaesu?s own ?DVC? (Direct Vertical Cooling) heat sinking system. A high-power, low-loss automatic internal antenna automatically rematches the antenna whenever SWR exceeds 2:1.
