Beschreibung: HF ALL BAND ALL SOLID STATE TRANSCEIVER
Informationen:
                                    ALL BAND, ALL MODE, ALL SOLID STATE
The IC-701 covers all the Amateur HF frequencies from 1.8MHz
to 29.999.9MHz plus 15MHz WWV. It offers not only SSB, but
also CW and RTTY. All of the circuits in the IC-701,
including the driver and final power stages are completely
solid state, and provide about 100 Watts output.
COMPUTER COMPATIBLE TUNING SYSTEM
The local oscillator circuit (VFO) employs a C-MOS LSI for
the PLL that has been custom-made on the basis of ICOM's
advanced digital technology. The VFO circuit is a digital
PLL circuit that controls frequency determination by pulses
produced by the tuning control. Unlike conventional PLLs, it
controls the VCO by combining and dividing crystal
oscillator frequencies. Therefore, its stability is much
higher than conventional VFOs. In addition, the pulse
control system makes it possible to set and change
frequencies with external digital signals.
With a computer programmed and connected to the rear
accessory socket, you can easily control frequencies, change
bands, scan, on the IC-701. This system will give you the
maximum of performance and versatility.
DUAL DIGITAL VFO'S
The IC-701 contains two built-in digital VFO's located in
ICOM's custom LSI, providing the ultimate in versitility.
DIGITAL READOUT AND FULL METERING
The frequency is presented in bright easy to read LEDs, with
no backlash or waiting time. The mulit-function meter shows
you relative signal strength in receive, power output, ALC,
SWR, compression level, final transistor voltage and
current. All the important information you need to know.
PASS BAND TUNING AND SPEECH PROCESSOR
The IC-701 has a built-in Pass Band Tuning system developed
by ICOM that allows you to continuously adjust the pass band
of the IF. By turning the control, you can eliminate
interference from a nearby signal, thus providing clear
reception. It can also be used as a tone control. During
transmit, the Pass Band Tuning circuit can be used as a
Speech Processor providing increased “talk power" for
outstanding DXing.
OUTSTANDING PERFORMANCE
The RF amplifier circuit using MOS FETs, the Schottky
barrier diode balanced mixer and other circuits provide
excellent Cross Modulation and Two-Signal Selectivity
characteristics. The IC-701 has excellent sensitivity
demanded especially for mobile operation, high stability,
and with two Crystal Filters having high shape factors,
exceptional selectivity.
The Same Schottky diode mixer is used in the transmitter,
and, with the band pass filter and high performance
K-Constant two stage low-pass filter, ensures transmission
of pure signals with very low spurious emission.
ADDITIONAL CIRCUITS
The IC-701 has a built-in Noise Blanker, VOX, an Auto Dimmer
for control of the readout and meter illumination, CW
Monitor, APC, SWR detector, and many other circuits for your
convenience.
The IC-701 has everything you need to really enjoy HF
operation, in an extremely compact, rugged transceiver.
