iPW1
HF/50 MHz ALL BAND
1 kW LINEAR AMPLIFIER
RWARNING HIGH VOLTAGE! NEVER attach
an antenna or internal antenna connector during trans-
mission. This may result in an electrical shock or burn.
RWARNING! NEVER carry the linear amplifier by
yourself. At least two persons must carry the linear
amplifier since it weights approx. 25 kg (55 lb).
RWARNING! NEVER apply AC voltage until the
linear amplifier is grounded. Touching the linear ampli-
fier may result in an electrical shock.
RNEVER apply AC voltage that exceeds the sug-
gested voltage. This could cause a fire or ruin the
IC-PW1.
RNEVER use an extension cord with the AC power
cable. Extension cords may cause fire or electrical
shock.
RNEVER let metal, wire or other objects touch any
internal part or connectors on the panel of the linear
amplifier. This will cause electric shock.
RNEVER expose the linear amplifier or remote con-
troller to rain, snow or any liquids.
NEVER allow children to play with the linear ampli-
fier or remote controller.
DO NOT operate the IC-PW1 before adjusting the
[ALC adj1] and [ALC adj2] pots properly on the rear
panel of the linear amplifier.
AVOID using or placing the linear amplifier or remote
controller in areas with temperatures below –10°C
(+14°F) or above +40°C (+104°F).
AVOID placing the linear amplifier or remote controller
in excessively dusty environments or in direct sunlight.
AVOID placing the linear amplifier against walls or
putting anything on top of the linear amplifier. This will
obstruct heat dissipation.
BE CAREFUL! The linear amplifier will become hot
when operating if continuously for long periods.
BE CAREFUL! Set the transceiver’s (exciter’s) RF out-
put power to less than 100 W, otherwise, the IC-PW1
will be damaged.
During maritime mobile operation, keep the linear am-
plifier, remote controller and microphone as far away
as possible from the magnetic navigation compass to
prevent erroneous indications.
The IC-PW1 cannot be used with the AH-2 HF AUTO-
MATIC ANTENNA TUNER.
For U.S.A. only
CAUTION: Changes or modifications to this device,
not expressly approved by Icom Inc., could void your
authority to operate this device under FCC regulations.
READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operate the lin-
ear amplifier.

•AC power cable connection (Except Europe version)
■ Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equip-
ment included with the IC-PW1, see UNPACKING on
p. ii of this manual.
■ Ferrite core installation
The supplied ferrite core and cable clips (o and !0 in
UNPACKING) should be attached to the AC cable of
the IC-PW1 as illustrated below. This will help prevent
interference such as TVI, etc.
■
OPC-853 AC cable with line filter
The IC-PW1 Europe version must be used with the
OPC-853 AC cable to satisfy European EMC require-
ments.
■ AC power cable connection
A suitable AC power plug must be connected to the AC
power cable end. See the diagram below for connec-
tion procedures. AC input voltage is automatically se-
lected.
The IC-PW1 can accept either 100–120 V AC or
200–240 V AC power.* However, we recommend using
200–240 V AC rather than 100–120 V AC for better
power supply efficiency and longer periods of trans-
mission.
*Europe version: 230 V AC only
■ Selecting a location
Select a location for the linear amplifier that allows ad-
equate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna ele-
ments, radios and other electro-magnetic sources.
The linear amplifier and remote controller sections of
the IC-PW1 can be separated. The remote controller
can be placed near the operator for easy monitoring of
linear amplifier conditions at any time. See p. 10 for
separation instructions.
The linear amplifier must be placed on a solid founda-
tion since it is very heavy.
Attach and position
the cable clips to
the AC cable as
illustrated.
AC cable
Ferrite core
Cut the cable clips
so that enough
length remains to
secure the ferrite
core in place.
■ Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the linear amplifier through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance be-
tween the GROUND terminal and ground as short as
possible.
R WARNING: NEVER connect the
GROUND terminal to a gas or electric pipe, since
the connection could cause an explosion or electric
shock.
■ Antenna
For radio communications, the antenna is of critical im-
portance, along with output power and sensitivity. Se-
lect antenna(s), such as a well-matched 50 Ω antenna
with more than 2 kW power rating, and feedline. 1.5:1
of Voltage Standing Wave Ratio (VSWR) is recom-
mended for a desired band. Of course, the transmis-
sion line should be a coaxial cable.
When using 1 antenna, use the [ANT1] connector.
CAUTION: Protect your linear amplifier from light-
ning by using a lightning arrestor.

e Slide the connector body on and solder it.
r Screw the coupling ring onto the connector body.
Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the lin-
ear amplifier’s power drops to protect the final FET.
In this case, an antenna tuner is useful to match the
linear amplifier and antenna. Low SWR allows full
power for transmitting even when using the antenna
tuner. The IC-PW1 has an SWR meter to monitor the
antenna SWR continuously.

■ System interconnections
1 or 2 Icom 100 W HF transceivers can be connected
as exciters to the IC-PW1. Non-Icom transceivers can
be used, however, band selection will not be synchro-
nized for each exciter.
See the following diagrams for making connections be-
tween the IC-PW1 and an exciter (transceiver). See p.

•Using non-Icom exciters
(transceivers) when the
IC-PW1’s power is OFF
To use the antenna selector of the
IC-PW1 when the IC-PW1 power
is OFF, follow 1 of 2 methods.
(1) Supply the antenna selector
power to the ACC-1 socket
Supply the 13.8 V DC, 0.5 A to pin
7 of the [ACC-1]/[ACC-2] socket.
- Use [ACC-1] when the exciter is con-
nected to [INPUT1].
- Use [ACC-2] when the exciter is con-
nected to [INPUT2].
(2) Use the auxiliary power
supply
Set the jumper to ‘2’ to use the
auxiliary power supply as shown at
right.
-The antenna selector functions even
when the IC-PW1 power is OFF
In addition set the jumper on the
IC-PW1 controller to ‘2’ to turn the
controller’s LEDs OFF as shown at
right.
When the jumper is set to ‘2,’
the CI-V control does not func-
tion even if an Icom exciter is
connected.
These diagrams show the factory de-
faults.

OPERATION
The IC-PW1 uses CI-V frequency data for automatic
selection of the operating band. Program the exciter’s
address to use this capability as follows:
For non-Icom exciters, the IC-PW1 cannot be con-
trolled using the CI-V function, so this setting is not
necessary.
For transceivers which have multiple antenna con-
nectors for specified bands (e.g. IC-726, IC-729,
etc.), set the same as for 2 Icom exciters.
D Setting the Icom exciters
When connecting 2 or more CI-V devices:
DO NOT use the “AUTO” baud rate for CI-V de-
vices. We recommend that all CI-V devices are set
to 9600 bps.
•When using the same baud rate, the exciters’ fre-
quencies are synchronized.
•When using different baud rates (i.e. 4800 and
9600 bps, etc.), the exciters’ frequencies are not
synchronized.
q Confirm that the exciter’s CI-V transceive function
is ON.
- Refer to the instruction manual for details.
w When connecting 2 exciters, connect the 1st and
2nd exciter to [INPUT1] and [INPUT2], respec-
tively.
e When connecting 2 Icom exciters, set [EXCITER]
to the [1&2] position.
r When connecting 2 or more CI-V devices, DO
NOT set to “AUTO” baud rate.
- Refer to the instruction manual for details.
- When using the same baud rate, the exciters’ frequen-
cies are synchronized.
- When using different baud rates (i.e. 4800 and 9600
bps, etc.), the exciters’ frequencies are not synchro-
nized. [INPUTz] and [INPUTx] selection is automat-
ically selected using the exciter’s baud rate.
D When using 1 Icom exciter
q While pushing [INPUT], push [POWER] to enter
the CI-V address programming mode.
- [INPUTz] blinks.
w Rotate the Icom exciter’s tuning dial until the
[INPUTz] light continuously lights.
e Push [POWER] to turn the IC-PW1 power OFF
and complete the setting.
D When using 2 exciter’s
q When using 2 Icom exciters, be sure that
[EXCITER] is set to the [1&2] position.
w While pushing [INPUT], push [POWER] to enter
the CI-V address programming mode.
- [INPUTz] blinks.
e Push [DOWN].
- The band indicators, [1.8]–[50], light continuously.
r Rotate the 1st Icom exciter’s tuning dial until the
[INPUTz] light continuously lights.
t When 1 Icom exciter and 1 non-Icom exciter are
connected, turn the power OFF to complete the
setting. When 2 Icom exciters are connected, push
[INPUT].
- [INPUTx] blinks when [INPUT] is pushed.
y Rotate the 2nd Icom exciter’s tuning dial until the
[INPUTx] light continuously lights.
u Push [POWER] to complete the setting.
D Setting the IC-PW1’s CI-V address
It is not necessary to change the IC-PW1’s default
CI-V address of 54H. However, if desired, the address
can be changed using the internal address switch il-
lustrated below.

OPERATION
CAUTION:
DO NOT operate the IC-PW1 before adjusting the
ALC levels properly with the [ALC adj1] and
[ALC adj2] pots. (p. 11)
It takes 15 sec. for CI-V line initial settings when
several CI-V devices (more than 5) are connected
to a CI-V line.
For IC-781 users with other Icom CI-V transceivers:
Turn the IC-781 power ON before turning the
IC-PW1 and other transceiver power ON and keep
the IC-781 power ON during operation.
q Push [POWER] to turn the linear amplifier ON then
turn the exciter’s power ON.
w Select the input/output antenna with [INPUT] and
[ANT].
e Set the exciter to CW or RTTY mode with minimum
output power.
r Select the temperature and SWR meters with
[METER-1] and [METER-2].
- The [TEMP] and [SWR] indicators light.
t Push [TUNER] and [AMP/PROTECT] to turn the
automatic antenna tuner and linear amplifier circuit
ON.
y Push [UP]/[DOWN] to select [AUTO] for automatic
band selection when a CI-V Icom exciter is used;
or push [UP]/[DOWN] to select the desired band
for manual band selection.
u Use the exciter’s antenna tuner to tune the line be-
tween the IC-PW1 and exciter, if you have an an-
tenna tuner connected to the exciter.
i Transmit with the exciter and adjust the exciter’s
output power to 50 W with the RF output power
control on the exciter.
- [TRANSMIT] indicator lights.
- See the exciter’s instruction manual for transmitting.
o The built-in antenna tuner automatically tunes the
antenna.
- SWR reading on meter-2 should be less than 1.2:1.
- Push [TUNER] for 2 sec. to tune the antenna manually.
- The [TUNER] indicator blinks while tuning.
- The [TUNER] indicator lights while the tuner is acti-
vated.
NOTE: The band information is not updated while
scanning. Turn the antenna tuner OFF and use the
manual band selection while scanning.
During split operation:
When changing the frequency more than 100 kHz,
the IC-PW1’s antenna tuner presets the tuner to
the new frequency. Use manual tuning during split
operation.
!0 When operating for long periods, select the tem-
perature meter with [METER-1] to monitor the lin-
ear amplifier’s temperature.
- If the temperature meter reading is in the red “HOT”
zone, the exciter should be returned to receive, other-
wise, the protection circuit may be activated and the lin-
ear amplifier may be turned OFF.
D Band memory
The IC-PW1 stores ON/OFF settings for the antenna
tuner and linear amplifier according to the operating
band when at least 1 Icom exciter is connected to the
[INPUT1] connector.
The set conditions may not be stored when the lin-
ear amplifier is turned OFF immediately after set-
ting the antenna tuner and linear amplifier.
■ Operation

OPERATION
14
This linear amplifier has various protection circuits.
D ALC circuit
The ALC (Automatic Level Control) circuit automati-
cally limits RF output power by controlling the input
level of the exciter. This prevents transmission of dis-
torted signals when the input signal level exceeds the
allowable level.
The ALC activates under the following conditions:
- Output power of the linear amplifier exceeds 1 kW
- Antenna SWR becomes 2:1 or more
- Output power of the exciter exceeds 100 W
D Cooling fans
•The power supply cooling fans activate when the lin-
ear amplifier is activated and while transmitting.
•The antenna tuner cooling fans activate when the
antenna tuner is activated and while transmitting.
•All cooling fans activate when the heatsink tempera-
ture of the final FETs reaches 50 °C (122 °F) or
more.
D Circuit breaker
If the circuit breaker activates or the linear amplifier
stops functioning, try to find the source of the prob-
lem, then push the circuit breaker button to fill the
white parts.
- Circuit breaker capacity: 20 A (U.S.A. version)
15 A (Europe version)
D Linear amplifier protection circuit
When a protection circuit is activated, a band indicator
blinks to show a problem as described below.
➥ [AMP/PROTECT] lights red when a protection cir-
cuit is activated.
- Push [AMP/PROTECT] to cancel the protection circuit.
The built-in automatic antenna tuner can match the
antenna feed line impedance to 50 Ω when the feed
line impedance is within 16.7 to 150 Ω for HF bands
(VSWR 3:1) or within 20 to 125 Ω for 50 MHz bands
(VSWR 2.5:1).
Once the tuner matches an antenna, the tuning cir-
cuit condition is memorized as a preset point for each
frequency range (100 kHz steps, 70 ranges). There-
fore, when you change the frequency range, the tun-
ing circuit is automatically preset to the memorized
point.
This antenna tuner is also used when the linear am-
plifier is turned OFF.
➥ Push [TUNER] for 2 sec. to start manual antenna
tuning.
•When the tuner cannot tune the antenna (SWR 1.5:1 or
greater), the tuning circuit is bypassed automatically
after 20 sec.
While operating in the 50 MHz band, the antenna
tuner does not start automatically. Push [TUNER]
for 2 sec. to tune the antenna manually.
