LONG
RANGE PROFESSIONAL HF TRANSCEIVER
Icom
IC-78* / IC-718
*
(IC-78 is export model, capable of transmitting/receiving over the entire
HF range).
Not
FCC-certified. Export and government sales only.
Reliable
straight forward HF communications
The IC-78 is a high
performance HF transceiver. Innovative features such as 99 memory channels,
high C/N ratio, direct channel entering, data communication capabilities
and more, offer easy operation for anyone. All these features come in a
compact, rugged package that can be conveniently used in a base station
or in a vehicle, as you prefer.
Durable, powerful construction
The IC-78 delivers a powerful
100 W of output power, providing the talk power you need to reach the most
distant locations. Its one-piece, die-cast aluminum construction combined
with a large heat sink, helps keep internal temperatures down and ensures
that operation is stable at high duty cycles. And its compact size of 240(W)
× 95(H) × 239(D) mm* makes installation
easy.
*9
7/16(W) × 3 3/4(H) × 9 13/32(D) in.
Simple operation
The IC-78 is equipped with
a large easy-to-read LCD. A minimum number of switches and controls allow
for superior feature selectability. Keys access functions directly__there's
no secondary function key. You can enter your operating frequency*,
or
memory channel number directly from the 10-key pad.

on version
Ample 99 channels with
8-digit channel name capability
An affordable 99 duplex
memory channels are available for storing individual transmit and receive
frequencies, operating mode, filter setting, as well as 8-character channel
names. You can enter channel assignments easily from the 10-key pad. In
addition, an extra 1 call memory is available for storing the most often
used, or most important frequency. An independent, one-touch recall switch
is available.
Superior basic performance
A 4-element system is employed
for the 1st receive mixer, providing superior receive IMD, especially from
in-band, nearby interfering signals. A well-designed doubleconversion system
to help minimize image and spurious responses for better signal fidelity,
is also built-in. A newly designed PLL circuit has been adopted to improve
C/N ratio characteristics. The combination of the 4-element system mixer
and new PLL circuit allows superior basic performance.
Front mounted loud speaker
With the speaker facing
the operator, audio sounds can be clearly heard without impediment during
operation. It is no longer necessary to manually increase the volume to
try and capture audio sounds.
High frequency stability
When the optional CR-338
HIGH STABILITY CRYSTAL UNIT is installed, it allows up to ±0.5 ppm
of extremely high stable operation.
Flexible filter selection
An optional IF filter can
be installed into the transceiver, providing 5 passband widths selectable
in SSB, CW or RTTY modes.
VFO mode operation*
For continuous frequency
operation, VFO mode operation* capability
is available. It is convenient when searching for signals, around the programmed
frequencies, such as short wave broadcasts, etc.
*depending
on version
Superior
features support serious communications
Direct channel selection
A 10-key pad has been adopted
on the front panel. A channel number, or an operating frequency*,
can be entered from the keypad directly. Also, memory channel editing is
possible. A large channel selector and up/down keys are available to suit
your operating style for your convenience. Total and simple operation is
provided!
*depending
on version
Cloning capability
Programmed data cloning
capability between transceivers is available, so that an identical transceiver
setting can be made immediately.
Built-in 2-tone alarm*
The 2-tone alarm for an
emergency signal transmission is built-in*. Independent
tone switch is adopted for quick and simple emergency calls.
*depending
on version
Data communications
In addition to the current
voice and key operation, FSK (First Shift Keying) type RTTY mode is available.
By connecting a terminal unit or terminal node controller to the ACC socket
on the rear panel, data acquisition and text-base file transfers and other
data communication can be made. On RTTY, shift width, tone frequencies
and polarization are also selectable.
Noise blanker
To reduce pulse-type noise,
a level adjustable noise blanker is built-in. Various levels of pulse-type
noise, such as from car ignitions, etc., can be reduced.
Pre-amp. and attenuator
A pre-amplifier and an
RF attenuator are adopted for more pleasant reception. Convenient when
weak signals or extremely stong signals are received, to present better
quality readability.
SQL/RF gain controller
In addition to the squelch
control, an RF gain control is available, and the controller is combined
with the squelch control. The RF gain adjusts minimum response receiver
gain, and ignores signals weaker than the pre-set level__providing
pleasant stand-by, or scanning. The SQL/RF GAIN controller action is selectable
from squelch only, RF gain only or combined, in the SET mode according
to your operating style and mode.
