1、For a bold, clean signal from Top Band through the Magic Band, the VL-1000/VP-1000 QUADRA SYSTEM belongs in your station! Innovative Ouadra Push-Pull RF Design for 1 kW of MOSFET Power! Yaesus engineers have conquered the challenging task of providing high power output from 160 through 6 meters!* Ya

2、esus exclusive Quadra Push-Pull design utilises 8 rugged MRF-150 MOS FETs for years of reliable operation. Special attention to system grounding and RF bypassing ensures very low spurious emissions, even at maximum power output. Powerful 16-bit Control CPU Provides High- Speed Antenna Tuning with Ex

3、tensive Memory and Multi-Band Memory Data Backup! The heart of the control circuitry of the VL-1000 is a 16-bit microprocessor, driven by a Yaesu-exclusive tuning algorithm in software. The on-board return- loss bridge analyses the antenna system performance, instantly sending tuning instructions to

The huge 190 x 43 mm dot-matrix LCD provides a wealth of amplifier-status information, including peak power output, average power output, voltage, current, and SWR data. Anothe

5、r Yaesu World First feature is the Panoramic SWR Monitor, which displays before tuning and after tuning SWR information for points across a band, providing you with instant data regarding antenna system performance. Active Safety Protection Assures Reliability and Quick Diagnosis of System Anomalies

6、! High power devices like the Quadra System need Direct Air Flow Cooling System Provides I Efficient Dissipation of Heat! Twin high-speed fans, thermostatically controlled, quietly direct cooling air across the 76 vanes of the heat sink, efficiently transferring heat out of the amplifier compartment

7、. Both the VL-1000 Amplifier and VP-1000 Power Supply have their own fan systems with independent thermostats. Automatic Band Change for Quick QSY! When operating with most modern Yaesu transceivers band data information can be transferred between transceiver and amplifier, allowing automatic amplif

8、ier band change when you change bands on the transceiver (Band Data Cable for FT-1000D/FT- 1000MP/FT-920 supplied)* The VL-1000 also provides Automatic Band Change via a frequency sensing circuit which instantly changes band when RF drive is first applied, for use with other exciters. Two Input and

9、Four Output Antenna Jacks for Versatile Integration Opportunities in Your Station! The two input jacks allow, for example, connection of an HF transceiver to INPUT 1 and a 6-meter transceiver to INPUT 2, while the four output jacks may be connected to your stations many antenna systems. Automated an

10、tenna selection is provided for the exciter connected to the INPUT 1 jack, eliminating the need for multiple antenna-selection keystrokes. High-Performance Switching Relays with Automatic Maintenance Mode! The VL-1000s high performance switching relays have been specified to provide years of fault-f
