IC-746PRO
HF/50MHZ/VHF ALL MODE
TRANSCEIVER

32-BIT DSP ON ALL BANDS
IC-746PRO incorporates the 32-bit DSP features to create some of the most flexible signal enhancing, and interference reduction ever offered in this type of radio. This enables the operator to create the listening environment that best suites the current band and conditions.

All Mode Digital Modulation and Demodulation
For signal purity and clarity, an all mode digital PSN (Phase Shift Network) system has been incorporated into the DSP system. The PSN separates the signal from noise by phasing out noise and other unwanted signals.

IF Filter Shapes
You will never have to purchase optional filters, with over 51 different filter widths, just dial in the width you want. Then select weather you want a sharp or soft filter shape for SSB and CW modes. For the digital operators, your filters are separate from the SSB filters.

Digital Twin PBT
Twin PBT allows electronically shift the upper and lower IF passbands, or shift the entire passband to eliminate interfering signal.

Digital RF Speech Compression
ICOM's Digital Speech Processor adds more punch to your signal to break through QRM.

Digital Noise Reduction
The DSP is able to reduce various types of noise and enhances the receive signal components. This provides an outstanding audio and signal to noise ratio which creats clean audio.

Microphone equalizer
The Microphone equalizer allows you to adjust bass and treble characteristics to toal 121 levels for all voice operations. The transmit filter width in SSB mode is selectable from 2.8/2.4/2.2 KHz. The RX tone control is also an equalizer for the received audio. As with transmit audio, select the amount of Bass and Treble you need for the audio clarity you want.

HF + 50 MHz + VHF All band coverage
Covering all HF bands as well as 50 MHz and 144 MHz, the IC-746PRO all mode transceiver also includes a genearl coverage receiver from 0.03-60 MHz and 108-174 MHz(*) with full IF DSP capability.
*) Specification guaranteed 0.5-29.99, 50-54 and 144-148 MHz only.

Continuous duty at 100W
The bipolar 2SC2694's are used to provide clean 100 watts of output power on SSB, CW, RTTY and FM modes (40W in AM). The die-cast aluminum chassis and the variable speed cooling fan enables the IC-746PRO to transmit full power all the time (on 50 OHm load at the room temperature).

Large, multi-function LCD
The large, multi-function LCD displays frequency, 9-character channel name, channel number, multi-functional meter (S-meter, RF output, SWR and ALC level) and other operating status. The dot-matrix portion of the LCD shows the following items:
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 decoded message.

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 change modes.

Ample CW functions
Multi-function electronic keyer, variable dot/dash ratio (2.8:1 to 4.5:1) and key speed (6-60WPM), paddle polarity, bug key etc. CW pitch is adjustable (300 to 900Hz). Full break-in capabilty. Double key jacks - one each for front and rear panel.

Memory keyer
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 (not supplied by ICOM) controls the memory keyer from your finger tips.
