HF TRANSCEIVER
IC-78
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.
*depending 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.
