Digital Twin PBT
Only Icom brings you Twin Passband tuning! Tailor your IF passband with the Twin
PBT by electronically shifting the upper and lower IF passbands. Depending on the
use of the concentric knobs, you can either narrow the IF passband, or shift the
entire passband to eliminate interfering signals.
Interference management is not a problem with the Manual Notch filter. With it’s
incredible 70dB attenuation, the manual notch can eliminate a wide variety of QRM.
The Automatic Notch Filter can track two or more interfering signals like Heterodynes
and “Key uppers”!
Digital Noise Reduction
By digitally manipulating the incoming signal, the DSP is able to reduce various
types of noise and enhances the receive signal components. Providing an outstanding
signal to noise ratio to give clean, clear audio.
AGC Loop Management
Another first in this class of transceiver, the IC-746PRO incorporates a multiple
AGC loop management system, which uses the DSP filtering to remove unwanted signals
from the AGC control. This means, if an unwanted signal is removed using the DSP,
the AGC will not be affected. In other words, “No more pumping of the AGC!”
Also, the AGC is independently controllable for mode and the time settings. (Off,
0.1-6.0 or 8.0 sec.)
Bring Hi-Fidelity to the amateur airwaves. The Microphone Equalizer will change
your RST from “59” to “Great Audio” and “Nice Signal”.
Adjust your audio for Bass and Treble characteristics to total 121 levels for all
voice operation. The transmit filter width in SSB mode is selectable from 2.8/2.4/2.2kHz.The
Rx tone control is also an equalizer for the received audio. As with the transmit
audio, select the amount of Bass and Treble you need for the audio clarity you want.
Digital RF Speech Compression
Need more punch in your signal; the Icom Digital RF Speech Compression gives you
all you need without fuss and noise. Great for breaking through QRM
HF + 50MHz + 144MHz All Band Coverage
Covering all HF bands as well as 50MHz and 144MHz, the IC-746PRO all mode transceiver
also includes a general coverage receiver from 0.03–60MHz and 108-174MHz* with full IF DSP capability.
* Specifications guaranteed 0.5–29.99, 50–54 and
Continuous Duty at 100W
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
variable speed cooling fan enables the IC-746PRO to transmit full power all the
time*; the perfect companion for those digital
* On a 50Ω load at room temperature.
The large multi-function LCD displays frequency, 9-character channel name, channel
number, multi functional meter (includes S-meter, RF output, SWR and ALC level)
and other operating status. The dot-matrix portion of the LCD shows the following
- Channel name
- Function key assignment
- Band Scope
- RTTY decoder screen
- Memory keyer contents
- Graphical SWR scale
RTTY Demodulator and Decoder
The built-in RTTY demodulator and decoder reads baudot RTTY signals on the screen
without turning on your PC or other gear. The RTTY tuning indicator helps critical
tuning. The Twin Peak filter removes interfering QRM giving you a more accurate
Ample CW Functions
Multi function electronic keyer, variable dot/dash ratio (2.8:1 to 4.5:1) and key
speed (6-60 WPM), paddle polarity, bug key etc. CW pitch is adjustable (300 to 900Hz).
Full break-in capability. Double key jacks – one each for front and rear panel.
4 channel memory keyer stores up to 50 characters with serial contest number auto-counter,
morse cut number and auto repeat function. In addition, a user supplied external
keypad* controls the memory keyer from your finger tips.
* Not supplied by Icom.
Built-in Antenna Tuner
The internal antenna tuner matches the HF and 50MHz bands automatically. After operating
on a band for the first time, the tuner memorizes the selected antenna and preset
point providing for very high speed tuning. 2 antenna connectors for HF and 50MHz
bands and 1 for 144MHz band is equipped on the IC-746PRO.
SSB/CW Synchronous Tuning
You no longer have to worry about losing a CW signal while tuning with SSB mode.
With the SSB/CW synchronous tuning, the frequency automatically shifts when you
