You are now the owner of the Yaesu VL-1000 Linear Amplifier, which brings you leading-edge technology for the ultimate in operating convenience and reliability. We appreci- ate your investment in Yaesu equipment, and wish you many years of satisfying operation using your new amplifier! The VL-1000 is an all-solid-state linear amplifier operating on the 160 through 6 meter amateur bands (USA version: 160-15 meters) at a power output level of 1000 Watts on CW and SSB (500 Watts on continuous data modes such as RTTY). The VL-1000 includes a built-in antenna tuner with 240 memories for tuning data, and microprocessor control of the tuning circuitry. The VL-1000 features input jacks for two different exciters, as well as four antenna jacks for connection of antennas for different bands. Extensive self-test, system monitoring, and protection circuits are provided, with status and tuning information being displayed on a huge Liquid Crystal Display panel. The separate VP-1000 Power Supply Unit provides the +48 Volts required by the PA transis- tors, as well as all required control voltages for the amplifier. The VL-1000 normally is powered via 220 Volt AC mains, although it can be operated, at the 500 Watt level, from 117 Volt AC power. We encourage you to read this manual thoroughly before beginning installation and operation of your VL-1000 Linear Amplifier. The details regarding proper installation and operating advice contained in these pages will help you derive maximum satisfaction from your new Yaesu equip- ment. Be certain to observe all due safety precautions when using this high-power device!

Caution! Lethal AC and RF voltages are present within the cabinets of the VL-1000 Lin- ear Amplifier and VP-1000 Power Sup- ply. Use extreme caution when open- ing the cabinet(s) to perform any alignment or adjustment steps, and take particular care to inspect inter- connection cables frequently to en- sure that they are in good condition. It is assumed that you possess tech- nical knowledge and experience con- sistent with your possession of an amateur radio license; this knowledge and experience are important tools which will aid in the successful instal- lation of this apparatus. Should you have any questions about the safe in- stallation of this equipment, consult your Yaesu dealer or seek the assis- tance of a professional installer. AC Power Connections (using VP-1000 Power Supply) The VL-1000 is usually operated from 220 Volt (nominal) AC power. With 220 Volt input to the VP-1000 Power Supply, full (1000 W) power output will be obtained from the VL- 1000, while 117 Volt input to the VP-1000 is possible at the 500 Watt power output level. The advanced switching-regulator power supply used in the matching VP-1000 Power Supply does not require any transformer re- wiring, nor any changing of a switch position; the power supply will operate from either 220 or 117 Volt line voltages without configuration changes. However, the AC power cable/plug configu- ration will be somewhat different, depending on the country in which you purchased your amplifier. In some countries, the VP-1000 is shipped with the standard 220 Volt connector appropriate for your location. In those areas where there are multiple 220 Volt connectors in common use, the VP-1000 is shipped with- out the power connector; one may be obtained at a local hardware or electrical supply store. Pictorial diagrams of the common 220 and 117 Volt AC connectors in use are shown be- low. When wiring your own connector, be ab- solutely certain to observe the proper polarity on the pin connections. Consult with an elec- trician if you have any doubts about your wir- ing! Be sure that your house wiring is capable of sufficient current capacity on the 220 Volt circuit to be used, especially if this circuit is shared with household appliances. It always is preferable to operate the VL-1000 from a dedicated 220 Volt circuit with its own circuit breaker. Transceiver or Exciter Interconnections The interface wiring to the transceiver or trans- mitter which drives the VL-1000 consists of: (A) A 50 coaxial cable for carrying RF drive power from each exciter to the amplifier; (B) A 2-conductor transmit/receive control cable which provides a closure to ground signal from the transceiver to the amplifier during transmission; (C) A (supplied) 2-conductor ALC (Automatic Level Control) line, used to limit the drive level from the exciter to the amplifier; and (D) When using a compatible Yaesu trans- UK PlugAustralian Plug European Plug USA Plug (viewed from plug prong side) VP-1000 AC Cable wiring (European version) (U.S.A version) Page 3VL-1000 Operating Manual Installation FT-920/VL-1000 FT-1000MP/FT-650/VL-1000 nected to the INPUT 1/PTT 1/ALC 1 jacks, and that all cables from exciter #2 are connected to the INPUT 2/PTT 2/ALC 2 jacks. When us- ing a BAND DATA cable for interconnection, you do not need the PTT cable for the correspond- ing exciter, as the T/R control signal will be made via the BAND DATA cable. ceiver, a BAND DATA cable may be con- nected which provides automatic band change and T/R control (thus eliminating the need for cable (B) above), and +48 V DC supply voltage On/Off control (if the REMOTE switch on the rear panel of the VL-1000 is set to the ON position). Typical installation diagrams are shown below. When two exciters are utilized, be cer- tain that all the cables from exciter #1 are con- Page 4VL-1000 Operating Manual connections labeled TX GND on the rear panel of the transceiver; do not, however, use the transceivers PTT jack, as it was designed for PTT input (via a footswitch, etc.), not for am- plifier control. Automatic Amplifier Tune-Up If you connect the supplied control cable be- tween the transceivers PTT or REMOTE jack and the VL-1000s BAND-DATA 2 jack, the trans- ceiver will automatically transmit when you press the amplifiers front panel F SET key (make sure that the MODE switch of the trans- ceiver is set to CW, RTTY, or some other con- tinuous mode, and set the DRIVE or RF PWR control fully clockwise, if you want to perform antenna tuning). To accomplish this function, pin 11 of the BAND-DATA 2 jack closes the transceivers PTT or REMOTE jack to ground, thus placing the transceiver in the transmit condi- tion. Automatic Amplifier Tune-Up using FT-1000MP Transceiver When using the VL-1000 in conjunction with the FT-1000MP transceiver, the front panel F SET key may be used to initiate an automatic tuning procedure for the amplifier. In order to accomplish this, Menu Item 7-9 on the FT- 1000MP must be set to “KEYER ” (which is its default value), and a control cable must be con- nected between the FT-1000MPs REMOTE jack and the VL-1000s BAND-DATA 2 jack. The required wiring for this cable is shown below. Installation Antenna Connections As many as four HF or 50 MHz antennas may be connected to the rear panel Antenna jacks, labeled ANT 1 ANT 4. The antenna to be used on a particular band will be memo- rized once you make the selection manually via the front panel ANT switch. See the “Op- eration” section of this manual for more de- tails. ALC Connections The VL-1000 provides negative-going ALC, which provides a negative voltage to the ex- citer which begins to appear when sufficient drive power from the exciter is being received; the voltage becomes of greater (negative) magnitude if the drive is increased, so as to prevent overdrive of the amplifier. The voltage range provided from the VL-1000 is 0 to 10 Volts DC, and this is compatible with all Yaesu transceivers as well as many exciters of other manufacture. At 1000 Watts of output power, the typical voltage generated for use with Yaesu transceivers is about 4 V DC. The ALC cable must be connected between the transceiver and VL-1000 to prevent over- drive of the amplifier, and especially to facili- tate the proper operation of the protection cir- cuitry if sudden antenna system problems should cause the SWR to rise to dangerous levels. PTT Connections These jacks, labeled PTT 1 and PTT 2, ac- cept T/R control signals from your exciter. Grounding the center pin of one of these PTT jacks will cause the amplifier to be placed in the “Transmit” mode. These jacks utilize a positive voltage (5V DC) at very low current (10 mA maximum), so they are compatible with most open-collector NPN transistor amplifier control circuits in mod- ern transceivers. Mechanical relays may also be used, so long as they are “floating” con- tacts that do not apply a voltage to the VL- 1000s PTT jacks. On Yaesu transceivers, use either the transistor or relay (Normally Open) Page 5VL-1000 Operating Manual Plug Pinout as viewed from rear panelas viewed from rear panel as viewed from rear panel as viewed from rear panel BAND-DATA 1CONTROL BAND-DATA 2DC48V IN +13.5 V TX GND GND BAND DATA A BAND DATA B BAND DATA C BAND DATA D TX INH NC GND REMOTE PS ALARM LOW POWER GND -12V INPUT +12V INPUT +48V INPUT +48V INPUT +48V INPUT +48V INPUT GND GND GND GND +13.5 V TX GND GND BAND DATA A BAND DATA B BAND DATA C BAND DATA D TX INH F SET COMMON F SET 1 F SET 2 NC NC NC GND RCA Plug GND or (-) SIGNAL or (+) Page 6VL-1000 Operating Manual 4. LOW Switch This switch selects the RF output power. When in the LOW position, the RF output power will be reduced to (approximately) 500 watts PEP, and “LOWLOWLOWLOWLOW” will appear on the dis- play. Note: This switch should be set to the LOW position when operating from a 100 117 VAC power source. 5. INPUT Switch Press this switch to toggle between the ex- citers connected to the INPUT 1 and INPUT 2 connectors on the rear panel. The indicator “INPUT 1INPUT 1INPUT 1INPUT 1INPUT 1” or “INPUT 2INPUT 2INPUT 2INPUT 2INPUT 2” will appear on the dis- play to indicate which exciter is in use. 6. ATT Switch This switch activates a 3 dB input RF power attenuator, to reduce excessive input power from the exciter. It should be on if exciter out- put exceeds 100 watts PEP, as is the case when using the FT-1000/D. The “ATTATTATTATTATT” indica- tor will appear on the display when this switch is on. Front Panel Controls and Switches 1. POWER Switch This switch turns the VL-1000 on and off. When the amplifier is turned off, the INPUT 1 jack is connected directly to the ANT 1 jack. If using a Yaesu transceiver with a BAND DATA cable, the VL-1000 AC power will be remotely controlled by the transceivers power switch when the REMOTE switch on the rear panel of the VL-1000 is set to ON. 2. OPERATE Switch Pressing this switch activates the power am- plifier section of the VL-1000. When the power amplifier is activated, “OPERATEOPERATEOPERATEOPERATEOPERATE” will appear on the display. Press this switch again to turn off the power amplifier section. 3. DIM Switch This switch selects the brightness level of the LCD display. In low-light situations, acti- vating the Dimmer may reduce excess bright- ness in the display. For normal room lighting, however, the Dimmer should be set to OFF for best visibility. Page 7VL-1000 Operating Manual When using the Grapfical SWR Meter dis- play, press and hold this switch for second to change the frequency span of the meter. 11. TUNER Switch Pressing this switch places the antenna tuner in the transmit signal path. When the antenna tuner is activated, the “TUNERTUNERTUNERTUNERTUNER” indi- cator appears on the display. Press this switch again to turn off the antenna tuner. 12. TUNE Switch This switch activates the auto-tune system manually. Normally, when the operating band is changed, the tuner will automatically adjust itself for the same antenna selection and matching impedance which was set the last time that band was used. Press this switch to retune if you are on a different part of the band, or if the SWR is still too high after automatic tuning. Manual-restart with this switch can be used to “force” rematching of the impedance presented by the antenna system at any time. 13. F SET Switch Press this switch to activate the exciter and tune up the VL-1000 automatically when us- ing the FT-1000MP (with the cable shown on page 4 connected between the BAND DATA 2 jack on the VL-1000 and REMOTE jack on the FT-1000MP). 14. CONTRAST Knob This knob used to adjust the LCD contrast. 15.
