A mpliFier

o perATion

Before operating, please check the following items: r Confirm whether wiring does not have a miss wiring again.

r Confirm that the AC power plug connect to 220 Volt AC power directly. The VL-2000 requires 220 Volt AC power for

1.5 kW operation r Confirm that the ATT switch is set to “on” position, when connect the exciter having exceed 100 watts PEP.

r Confirm that the antenna SWR is less than 1.5:1.

1. Turn the VP-2000 POWER switch “on”, then turn the VL-2000 POWER switch “on”.

2. Turn the transceiver’s POWER switch “on”.

If using a Yaesu transceiver with a BAND DATA Cable, and the REMOTE switch on the rear panel of the

VL-2000 is set to “on”, the VP-2000 AC power will be remotely controlled by the transceiver’s POWER switch.

3. Set the INPUT switch to the position which is connected to the exciter.

4. Select the amateur band of the transceiver you wish to operate on.

If using a Yaesu transceiver with a BAND DATA

Cable, band selection will occur automatically whenever you change bands on the transceiver. Otherwise, select the amateur band of the VL-2000 to same as the transceiver.

5. Select the operating mode of the transceiver you wish to operate on.

6. Set the OPERATE switch to “on”. The “OPERATE”

LED will glow red.

7. Press and hold the TUNE button for 1/2 second to begin automatic tuning. The transmitter will be engaged, and the red TUNE LED will blink while tuning is in progress. When the optimum tuning point has been reached, the transceiver (and VL-2000 ) will return to receive, and the TUNE LED will glow red steadily (instead of blinking).

8. For SSB and CW operation , make sure to adjust the

Microphone Gain and/or Drive control on the transceiver for proper ALC indication on the transceiver

ALC meter, as described in the transceiver manual.

Generally, for SSB, the ALC meter indication should not deflect beyond a certain ALC limit (the “ALC” zone on the transceiver’s meter) on voice peaks; on

CW, the ALC indication should be just enough to cause slight meter deflection. Higher ALC levels may produce distortion or key clicks, without producing any additional power output.

In the CW mode, the VL-2000 allows you to full break-in operation. However, the full break-in operation may give the stress to the T/R switching relays.

For FM, SSTV, RTTY, or Packet operation , You may enable 1.5 kW operations, if the following condition is satisfied.

r Normal Temperature: +41 °F to +95 °F

(+5 °C to +35 °C) r Normal humidity (45 % to 85 %) r Side Clearance: 10 inches (25 cm) r Rear Clearance: 12 inches (30 cm).

Otherwise, press the LOW switch to select the LOW power condition to prevent the overheating during continuous operation.

For AM operation , adjust the Drive or RF Power control on the transceiver so that the METER-1 (“PO” meter) on the VL-2000 does not exceed 375 watts (on

1.5 kW operation) or 125 watts (on 500 watt operation) when transmitting a carrier.

o perATinG

p recAuTionS

Summarized below are some precautions to adhere to in order to ensure long life and trouble-free operation with the VL-2000 .

r Do not turning the POWER switch “on” or “off” while transmitting.

r When changing bands, always make certain that the VL-2000 is set for the same band as the transceiver before transmitting, and that the proper antenna is connected.

Remember that, when the VL-2000 is switched “off” the INPUT-1 jack is automatically connected to the ANT

1 jack and the INPUT-2 jack is automatically connected to the ANT DIRECT jack.

r Reduce the drive power (set the ATT switch to “on”), if the exciter output which you connected exceeds 100 watts PEP.

o perATion

The Automatic Antenna Tuner built into the VL-2000 is crafted to ensure a 50-Ohm load for the final amplifier stage of the linear amplifier. We recommend the Automatic Antenna Tuner be used whenever you operate the VL-2000 .

A dvice

: r The VL-2000 Automatic Antenna Tuner, being located inside the station, only adjusts the impedance presented to the transmitter at the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feedpoint itself.

When designing and building your antenna system, we recommend that every effort be made to ensure a low SWR at the antenna feedpoint.

r The VL-2000 Automatic Antenna Tuner includes 470 memories for tuning data. These memory allocation is described in the bottom chart.

r The VL-2000 Automatic Antenna Tuner is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, corresponding to an SWR of 3:1 or less on the HF amateur bands (6 meter amateur band: 25 Ohms to 100 Ohms, corresponding to an SWR of 2:1 or less). Accordingly, simple non-resonant whip antennas, along with random-length wires and the “G5RV” antenna (on most bands) may not be within the impedance matching range of the Automatic Antenna

Tuner.

r The VL-2000 Automatic Antenna Tuner is located between the final amplifier and the rear-panel antenna jack; reception is not affected by the Automatic Antenna Tuner.

1. Confirm the operating band of the VL-2000 is same as the exciter.

2. Press the TUNE button briefly to place the Automatic

Antenna Tuner in the transmit line. The TUNE LED will glow red.

3. Press and hold the TUNE button for 1/2 second to begin automatic tuning. The transmitter will be engaged, and the red TUNE LED will blink while tuning is in progress. When the optimum tuning point has been reached, the transceiver (and VL-2000 ) will return to receive, and the TUNE LED will glow red steadily (instead of blinking).

4. To disconnect the Automatic Antenna Tuner from the transmit line, press the TUNE button briefly.

The TUNE LED will turn off, confirming that the

Automatic Antenna Tuner has been turned off. In the

“off” mode, the transceiver will be directly connected to the coaxial cable connected to your antenna, and it will operate based on whatever impedance is present at the station end of the coax.

The VL-2000 Automatic Antenna Tuner makes a note of the positions of the tuning capacitors and the selected inductors when the tuning result is better than SWR 1.5:1. This eliminates the need to re-tune every time you return to a frequency on which you already have completed the tuning process.

n oTe

The VL-2000 Automatic Antenna Tuner does not tuning in the following situations: r The exciter (transceiver) is not transmitted.

r No carrier.

r Low injection level.

r Antenna SWR is more than 3.0: 1.

(short-circuit or open-circuit) r Tuning result is more than 3.0: 1.

So2r F eATure

The SO2R (Single Operator Two Radios) feature allows you to receive the two signals by the two transceivers simultaneously, when connects the two radios to the VL-

2000 . Furthermore, you to operate the VL-2000 without changing the INPUT switch. The VL-2000 switches the input to the transceiver side which transmitted automatically, regardless the INPUT switch setting.

To activate the SO2R feature, turn “on” the SO2R switch on the rear panel of the VL-2000 .

n oTe r The VL-2000 Automatic Antenna Tuner works only to the transceiver which connected to the

INPUT jack that is determined by the INPUT switch.

r Cannot select the same antenna in INPUT 1 and INPUT 2 while SO2R feature is activated.

A dvice

Even if the SO2R switch is “off”, you can connect the two transceivers deservedly. However, you must switch the INPUT switch to the position which is the transceiver that is transmitted manually and you can not receive the signal with the other transceiver while the transceiver is transmitted.

Operation

AnTennA direcT F eATure

The ANTENNA DIRECT feature outputs the INPUT

2 signal to the ANT DIRECT jack directly after having passed the Linear Amplifier and the Automatic Antenna

Tuner. As a result, the transmit signal does not pass a complicated antenna change circuit, to keep the loss at the minimum.

To activate the ANTENNA DIRECT feature, turn “on” the DIRECT switch on the rear panel of the VL-2000 .

When activates the ANTENNA DIRECT feature, the all ANT LED ( ANT 1 ~ ANT 4 ) turns “off”, confirming that the ANTENNA DIRECT feature has been activated.
