HF TRANSCEIVER
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.
*9716(W)334(H)91332(D) in.
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.
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
is installed, it allows up to
0.5 ppm of extremely high stable operation.
CRYSTAL UNIT
Flexible filter selection
Superior basic performance
Simple operation
The IC-78 is equipped with a large easy-toread LCD. A minimum number of switches
and controls allow for superior feature selectability. Keys access functions directly
theres no secondary function key. You can
enter your operating frequency*, or memory channel number directly from the 10key pad.
*depending on version
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 double-conversion 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 4element system mixer and new PLL circuit
allows superior basic performance.
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
Cloning capability
Data communications
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!
Programmed data cloning capability
between transceivers is available,
so that an identical transceiver setting can be made immediately.
*depending on version
*depending on version
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
SQL/RF gain controller
Other features
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.
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.

Pre-amp. and attenuator
A pre-amplifier and an RF attenuator are adopted for more pleasant
reception. Convenient when weak
signals or extremely strong signals
are received, to present better quality readability.
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.
