POWER Switch
This switch turns the VL-2000 “on” and “off”.
When the VP-2000 [POWER] switch is set to the
“off” position, this switch will not function.
If using the Yaesu transceiver with a BAND DATA
Cable, the VP-2000 AC power will be remotely controlled by the transceiver’s power switch when the
REMOTE switch on the rear panel of the VL-2000 is
set to “on”.
Caution: Never turn “off” this switch while transmit-
ting.
METER-1 Switch
Press this switch to toggle the METER-1 function be-
tween “PO” meter and “SWR” meter.
METER-1
This is the two functions (PO/SWR) meter which is
determined by the “METER-1” switch selection.
PO: Indicates the RF Power Output, from 0 to 2k
watts on transmit.
SWR: Indicates the antenna system observed stand-
ing wave ratio (SWR), from 1.0 to 5.0.

from 0 to 75 A.
VDD: Indicates the final amplif ier d rain volt age
(nominal value: 48 V).
TX Indicator
This indicator glows red when the VL-2000 is trans-
mitting.
OPERATE Switch

tor, to reduce excessive input power from the exciter.
It should be “on” if exciter output exceeds 100 watt
PEP, as is the case when using the FTDX9000 series
transceiver. The LED will glow red, when this switch
is “on”.
Note: This switch does not effect while transmitting.
INPUT Switch
This switch selects the exciters which connected to
the INPUT1 and INPUT2 jacks on the rear panel.
The “INPUT1” or “INPUT2” LED will glow red to
indicate which exciter is in use.
Note: This switch does not effect while transmitting.

This is the on/off switch for the VL-2000’s Automatic
Antenna Tuner.
Press this button briey, places the antenna tuner in
line between the transmitter final amplifier and the
antenna connector (The LED will glow red, and reception is not affected).
Press and hold this button for 1/2 second, while re-
ceiving in an a mature band, activates the transmitter
for a few seconds while the Automatic Antenna Tuner
rematches the antenna system impedance for minimum SWR. The LED will blink red when the antenna
tuning is processing.
Pressing this button briefly, while the Tuner is en-
gaged, will take the Automatic Antenna Tuner out of
the transmit line.
HI-SWR LED
This LED blinks red when the antenna system is ab-
normally high SWR condition (over 3.0:1) that cannot
be resolved by the Automatic Antenna Tuner.
When this LED blinks, the exciter output delivers to
the antenna connector directly without through a linear amplier.
Note: Check to be sure that you have the correct an-
ten na selected on the current operating band when
this LED blinks red. If so, you will need to check the
condition of the antenna, its coaxial cable and/or the
connectors on the cable so as to locate and correct
fault.
ANT Button
These momentary buttons select the antenna jack on
the rear panel, with the selection indicated by the red
LED in each button.
Note: These buttons does not effect while transmit-
ting.
BAND Button
These momentary buttons select the amateur band for
the operation, with the selection indicated by the LED
in each button.
If using the Yaesu transceiver with a BAND DATA
Cable, the VL-2000 operation band will be remotely
controlled by the transceiver’s BAND switch.
Note: These buttons does not effect while transmit-
ting.

Before operating, please check the following items:
r Conrm whether wiring does not have a miss wiring again.
r Conrm 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 Conrm that the ATT switch is set to “on” position, when connect the exciter having exceed 100 watts PEP.
r Conrm 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 Ca-
ble, 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 con-
nected 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 deection. 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
satised.
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.
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 ANTDIRECT jack.
r Reduce the drive power (set the ATT switch to “on”), if the exciter output which you connected exceeds 100
watts PEP.

AuTomATic AnTennA Tuner operATion
The Automatic Antenna Tuner built into the VL-2000 is crafted to ensure a 50-Ohm load for the nal amplier stage of
the linear amplier. We recommend the Automatic Antenna Tuner be used whenever you operate the VL-2000.
Advice:
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 nal amplier and the rear-panel antenna jack; recep-
tion is not affected by the Automatic Antenna Tuner.
1. Conrm the operating band of the VL-2000 is same
as the exciter.
2. Press the TUNE button briey 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 Anten na Tuner
from the transmit line, press the TUNE button briey.
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.

Advice
The VL-2000 Automatic Antenna Tuner makes a
note of the positions of the tuning capacitors and
the selected inductors when the t uning 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.
noTe
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.
reSeTTinG The AnTennA TuninG dATA
The VL-2000 can be reset so as to clear the antenna tuner tuning data; this will be reset to the
factory default.
To reset the Antenna Tuning Data, press and hold
in the TUNE button while you turn the VL-2000
on.

So2r FeATure
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.
noTe
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 INPUT2 while SO2R feature is activated.
Advice
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.
AnTennA direcT FeATure
The ANTENNA DIR ECT featu re outputs the INPUT
2 signal to the ANTDIRECT jack directly after having
passed the Linear Amplier 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.
imporTAnT noTe
When activates the ANTENNA DIRECT feature,
the all ANT LED (ANT 1 ~ ANT4) turns “off”,
conrming that the ANTENNA DIRECT feature
has been activated.
