HF/50 MHz. All Mode Transceiver
Nothing else comes close. |

ICOM IC-7800 |
| |
|
ICOM has been the world pioneer
in amateur radio for 40 years.
The first to bring transistor technlogy, digital PLL
technology and the latest DSP technology to name a few
achievements. It is therefore fitting that ICOM brings
you the most advanced amateur radio ever in the IC-7800!Starting with the 32-bit DSP
processor and 24-bit AD/DA converter, ICOM enables the
ham radio operator to create the listening environment
that best suites the current band and operating
conditions.
No less than four 32-bit
floating point DSP chips, two completely independent
receivers, 7-inch wide TFT display, RTTY/PSK31 encoder
and decoder and compact flash technology are but a few
of the amazing features this mighty rig offers. Simply
the best, simply the ultimate in amateur radio is now a
reality for you to enjoy first hand. |
| |
|
Four 32-bit floating point
DSP units.
Four independent DSP units are
used. One for the transmitter, one for each receiver,
and the final one for the spectrum scope. The IC-7800
builds on the phenomenal performance of the 32-bit DSP
that ICOM introduced to the amateur world. With the
24-bit AD/DA converter, this powerful combination
supports many DSP features exclusive to the IC-7800. |

|
+40dBm ultra high intercept
point.
By sparing no expense
throughout the signal chain, ICOM has developed an
amateur rig that challenges the performance of any
“Military Grade” transceiver. You’ll enjoy a +40dBm* 3rd
order intercept point and ultra wide dynamic range that
is amateur radio’s highest. The IC-7800 is the new bench
mark for HF transceivers. Examples include the use of
mechanical relays
instead of traditional semi-conductor and
highperformance DMOS mixers with a high-drive Local
Oscillator. Using only two IF stages and ICOM’s new
image rejection technology, enables the IC-7800 to
clearly reproduce very weak signals as well as very
strong signals without distortion. * HF bands, pre-amp
off. |
| |
|
Automatic tracking
pre-selector.
As your first line of defense
against interfering signals, the pre-selector rejects
unwanted out of band interference from multi-multi
operation or strong broadcast stations. The 7800’s
pre-selector automatically tracks the intended signal,
keeping the pre-selector’s bandwidth centered on the
operating frequency. |
| |
|
Two completely independent
receiver circuits.
As the same “Military Grade”
receiver is duplicated for the second receiver, the
IC-7800 is like having two rigs in one box. Thus the
ultimate in dual receiver performance is at your
control; the receivers are completely independent all
the way from the 4 antenna jacks, through the
pre-selector, DSP, signal detectors, front panel
control, right into the stereo headphone! In addition
to the separate receivers, the audio amplifiers and
control circuits are duplicated for either headphones or
external speakers. The true dual receiver takes your
band hopping and contesting experience to the next
level. |
| |
|
200W output power at full
duty.
Newly designed push-pull
MOS-FET amplifiers work with 48V DC, providing a
powerful 200W of output power at full duty cycle with
low IMD in all bands. A low noise switching power supply
is built in. |
| |
|
Ultra high frequency
stability.
Your IC-7800 will be the
reference on the band with a standard stability of ±
0.05 ppm! Even on 6m band, that is less than 3Hz error
from the Oven Controlled Crystal Oscillator! Also, a 10
MHz reference frequency can be be input/output for
external equipment
|
| |
|
7-inch wide color TFT LCD.
The large 7-inch wide (800x480
pixels) color display has to be seen to bee believed!
High linearity needle S-meters, multi function spectrum
scope and RTTY/PSK31 messages are displayed in vivid
color. In addition, the IC-7800 has a VGA connector
allowing you to connect an external monitor |
| |
|
Multi function spectrum
scope.
With the dedicated DSP unit,
the spectrum scope offers linearity, accuracy and
resolution. By adjusting the scope selectivity
(resolution band width), the spectrum scope allowsyou to
find those weak signalsright next to strong ones! With
this ground breaking scope, you can even monitor the
distortion or width of the received signals. In
addition, the scope range can be set independently from
the receiving frequncy. You can monitor the band
condition between the
selected sweep edges, as well as dweep a selected band
width centered on the receiving frequency in the scope
screen. |
| |
|
RTTY/PSK31 operation without
PC connection.
The IC-7800 has a modulator
and demodulator for the 2 major HF Amateur digital
modes. It is possible to encode and decode PSK31 as well
as baudot RTTY signals by simply connecting a USB
keyboard to the IC-7800. You no longer need to connect a
PC for RTTY/PSK31 operation. In addition, transmitted
and received messages can be stored to the CF card
memory and transfered to your PC. |
| |
|
IF notch filter with
adjustable notch filter characteristics.
The bipolar 2SC2694’s are used
to provide a clean 100 watts of output power for SSB,
CW, RTTY and FM modes. ( 40W in AM). The die-case
aluminum chassis and the riable speed cooling fan
enables the IC-7400 to transmit full power all the
time*; the perfect companion for those digital mode
contests. * On a 50Ω load at room temperature. |
| |
|
Professional 6m receiver.
While most HF/50MHz
transceiver share the preamp between the HF bands and
50MHz band, the IC-7800 uses an exclusive preamp and
mixer especially for 50MHz. This preamp and mixer are
tuned to the 50MHz band and improve cross modulation
characteristics, particularly important when picking up
a very weak signal near a strong station. |
|
|
|
Digital Voice Recorder.
The Digital Voice Recorder
(DVR) is a convenient function for contests, DX
peditions, field day and even normal operation. |
|
|
|
CF (Compact Flash) memory
card.
An IC-7800 has a CF card slot
and aCF card will be supplied with the IC-7800. You can
store your various settings such as filter, display, mic
equalizer, etc. on your card. When sharing the IC-7800
with multi users such as on a DX pedition, in a contest
or as a club rig, the CF card allows you to restore your
personal settings instantly. |
