Ic-746 pro manual
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. Manual Notch Filter Interference management is not a problem with the Manual Notch filter. With it’s incredible 70d B 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-746 PRO 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, or 8.0 sec.) Microphone Equalizer 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 /2.2k Hz. 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.
Features | Specifications | Accessories | LCD | Rear Panel | Larger Image Following on the success of the Icom IC-746, the Icom IC-746 Pro covers 160-10 meters plus 6 and 2 meters all mode. 100 Watts of output is available on all bands - HF, 50 MHz and 144 MHz, making the IC-746 Pro a practical choice for all-around base station use. The die-cast aluminum chassis and a large cooling fan help to stabilize the PA circuit, providing 100% full duty cycle operation. The new Pro version features 32 bit floating point DSP and 24-bit AD/ DA converter. This combination dramatically improves receiver performance providing ultra wide dynamic range and good third order intercept point. An there are NO more expensive optional filters to buy. The digital IF filter allows your to select 51 filter bandwidths. There are three user selectable filter memories per mode. Soft and sharp filter shapes can be selected in both SSB and CW modes independently. You can also change the settings on the fly and compare! For repeater operation theres is a built-in tone encoder and decoder with 50 CTCSS and 108 DTCS based tones. There is even a built-in Baudot RTTY demodulator. It has 100 alphanumeric memories, digital RF speech compression, spectrum display, Manual and Automatic Notch, digital Twin PBT, Noise Blanker, CTCSS encode/decode, APF, two stage preamp, automatic antenna tuner and electronic keyer. A built-in automatic antenna tuner operates on the HF bands plus 6 meters. The 746 Pro requires 12 VDC at 23 Amps. The IC-746 Pro comes with HM-36 hand mic, spare fuses, OPC-025 DC power cable and key plug. 11.3 x 4.8 x 12.5 inches. 20 lbs. See the May 2002 issue of QST for a great review of this radio.
