IMPORTANT
READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operate the linear amplifier.
SAVE THIS INSTRUCTION MANUAL. This instruction manual contains important safety and operating instructions for the IC-PW1.
PRECAUTIONS
RWARNING HIGH VOLTAGE! NEVER attach
an antenna or internal antenna connector during transmission. 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 amplifier may result in an electrical shock.
RNEVER apply AC voltage that exceeds the suggested 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.
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 output power to less than 100 W, otherwise, the IC-PW1
will be damaged.
During maritime mobile operation, keep the linear amplifier, 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
RNEVER expose the linear amplifier or remote con-

INSTALLATION AND CONNECTIONS
■ Unpacking
■ AC power cable connection
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
A suitable AC power plug must be connected to the AC
power cable end. See the diagram below for connection procedures. AC input voltage is automatically selected.
For a description and a diagram of accessory equipment 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.
* Europe version: 230 V AC only
■ Selecting a location
Select a location for the linear amplifier that allows adequate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna elements, radios and other electro-magnetic sources.
Attach and position
the cable clips to
the AC cable as
illustrated.
Ferrite core
AC cable
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 transmission.
Cut the cable clips
so that enough
length remains to
secure the ferrite
core in place.
■ OPC-853 AC cable with line filter
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 foundation since it is very heavy.
The IC-PW1 Europe version must be used with the
OPC-853 AC cable to satisfy European EMC requirements.
•AC power cable connection (Except Europe version)
(1) Single-phase 3-wire line (200–240 V AC)
q The green wire from the AC power cable must be
connected to the protective earth.
w The black and white wires from the AC power
cable can be connected to either terminal.

INSTALLATION AND CONNECTIONS

■ Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other problems, 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 between 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 importance, along with output power and sensitivity. Select 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 recommended for a desired band. Of course, the transmission line should be a coaxial cable.
When using 1 antenna, use the [ANT1] connector.
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 linear 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.
CAUTION: Protect your linear amplifier from lightning by using a lightning arrestor.

INSTALLATION AND CONNECTIONS
■ 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 synchronized for each exciter.

■ Programming the CI-V address
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:
w Rotate the Icom exciter’s tuning dial until the
[INPUT z] light continuously lights.
e Push [POWER] to turn the IC-PW1 power OFF
and complete the setting.
For non-Icom exciters, the IC-PW1 cannot be controlled using the CI-V function, so this setting is not
necessary.
D When using 2 exciter’s
For transceivers which have multiple antenna connectors for specified bands (e.g. IC-726, IC-729,
etc.), set the same as for 2 Icom exciters.
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.

OPERATION

■ Antenna tuner operation
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 circuit condition is memorized as a preset point for each
frequency range (100 kHz steps, 70 ranges). Therefore, when you change the frequency range, the tuning circuit is automatically preset to the memorized
point.
This antenna tuner is also used when the linear amplifier 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.
■ Protection circuit
This linear amplifier has various protection circuits.
D ALC circuit
The ALC (Automatic Level Control) circuit automatically limits RF output power by controlling the input
level of the exciter. This prevents transmission of distorted signals when the input signal level exceeds the
allowable level.
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 circuit is activated.
- Push [AMP/PROTECT] to cancel the protection circuit.
