Receiver

High Performance Receiver

A measurable improvement in the newly designed 4-element system for the IC-756PROII, delivers a well respected 3rd order intercept point. ICOM engineers made improvements in the input filter, buffer amplifier, and other electronic components from the RF stage to the mixer stage. The result is less distortion from strong signals.

Receiver Basics

A perfect balance of analog and digital brings one of the most exciting receivers to life. With controls over the sensitivity of the receiver from the 2- level pre-amplifier and 3-level attenuator, virtually any signal can be added to your log.

Level Adjustable Noise Blanker

A fully adjustable ( 101 steps)noise blanker reduce annoying QRN and other QRM.

Dual Watch

The dual watch fuction allows you to receive 2 signals on the same band simultaneously.

CW Carrier Point Selectable

Until now the carrier point of the CW mode was LSB only. Now, the carrier point of the normal ( defoult) CW mode is selectable from USB and LSB.

SSB/CW Synchronous Tuning

No longer worry about losing a CW signal while tuning through the bands. With the SSB/CW Synchronous Tuning, the frequency automatically shifts when you change modes.

Transmitter

Highly Stable Transmitter

The IC-756PROII utilizes two 2SC5125 transistors in the PA Unit for 100W full duty cycle operation. For perfect audio a Digital Phase Shift Network ( DPSN) is used in the SSB modulator, providing clear and high quality transmit audio for voice and data mode operations.

Microphone Equalizer

The built-in audio equalizer, with a separate bass and treble adjustment, has a total of 121 combinations. You can get the warm, full audio you want. The transmit bandwith is selectable from 2.2, 2.4, and 2.8 kHz to suit operating band conditions.

Digital RF Speech Compressor

The IC-756PROII utilizes the 32-bit DSP for the RF speech compressor providing the maximum punch without the fuzzy sound.

High Stability Crystal Unit

The IC-756PROII incorporates a POC type crystal oscillator, providing ±0.5ppm (-10º C to + 50º C). A must for digital or MARS ( Military Affiliate Radio System) operation.

Related Features

• Hear your Tx audio with the Tx monitor fuction, perfect for headphone operation.

• 50 frequency tone encoder for 10m and 6m repeater operation with Tone scan.

• Hands free operation with the VOX function.

• Complete control of output RF power with the variable RF control.

• Quick split function with split lock capability.

Build Your Own Filter

The PROII takes the 756PRO's built-in IF filters to the next level. Now, you can adjust the shape of the filter to best suit your operation style ore band conditions.

32-Bit Floating Point DSP Unit & 24-Bit AD/DA Converter

The IC-756PROII continues the phenomenal performance of the 32-bit floating point DSP from the IC-756PRO. The 24-bit AD/DA converter makes it possible to provide ultra-wide dynamic range of signal management.. This poweful combination supports many DSP features exclusive to the IC-756PROII.

Sharp and Soft Filter Shapes are Selectable Each for SSB and CW Mode

Select an appropriate filter shape, depending on your operating style or band conditions. Independent SSB and CW Filters give you the flexibility you want while listening to the signal.

Digital Twin PBT

By moving the IF pass band, the digital twin Pass Band Tuning (PBT), allows the flexibility of both IF shift and narrowing of the IF passband. With the digital IF filters, the PBT performance allows you to cut away all the interference and noise to hear the actual signal.

Manual Notch Function

An incredible 70 dB of attenuation is at your command with the manual notchEliminate strong adjacent signals or beat tone noise, without reducing the performance of the AGC gain.

Automatic Notch Function

Eliminate those annoying AM carriers, amplifier or radio tune up interference with a push of a button. The automatic notch locks will eliminate 2 or more interfering signals simultaneously without signal loss or distortion. Very helpful on 160 and 80 meters.

Noise Reduction

The 32-bit DSP processing power of the IC-756PROII produces real results by separating a signal component from the noise with the variable Noise Reduction. By suppressing the noise components, an outstanding signal to noise ratio is achieved, providing clean,clear audio in all modes without distortion of the target signal.

AGC Loop Management

The AGC system is incredibly impressive with the rejection of unwanted signals or noise. The AGC in the IC-756PROII will be able to copy weak signals without the pumping of the AGC from stronger adjacent signals.

Visualize Your Possibilities

More than just a pretty face, the multifunction 5-inch TFT color display allows you to see signals, settings and many other operating functions at a glace.

RTTY Demodulator and Decoder

The IC-756PROII has a built-in RTTY demodulator and decoder that reads baudot RTTY signals on the screen.

Twin Peak Audio Filter

The 32-bit DSP improves RTTY reception with the Twin Peak audio filter by automatically peaking the areas of the mark and space frequenties. This function removes interfering QRM giving you a more error free decoded message.

50 Hz passband width for PSK31 mode

The PSK31 uses only 31Hz of passband width. The IC-756PROII makes it possible to narrow a passband to 50Hz in SSB mode, sothat only intended signals can be heard clearly. In addition, a POC type crystal unit delivers superior frequency stability, with 1Hz step tuning, that is ideal for delicate digital mode operation.

Data Communication

The IC-756PROII offers Data operation on SSB,AM and FM modes. Special filters, Band Pass Filters (BPF), are automatically selected when the IF filter passband is reduced to 500Hz or less in SSB mode. The BPF automatically sharpens for better rejection of interfering signals. Perfect for PSK31, SSTV or other AFSK modes.

5-inch TFT color LCD

Enjoy the full 5-inch TFT color display. The IC-756PROII extends its functionabilty with more disply adjusments, color types and improved contrast. In fact, 8 colors of display settings and 7 types of font settings are available. Various information is indicated on the color LCD, separated into an upper and lower screen. The lower screen can spread vertically to increase the information viewing area.

Operation

Digital Voice Recorder

The Digital Voice Recorder ( DVR) in the IC-756PROII is a very convenient function for contests, DX' peditions, field day and normal operation. Record your callsign, CQ, or other station information into four memory locations. A total of 90 seconds is available for the four memories.

External Control Capability for Voice Memory and Memory Keyer

For more convenient control of the DVR and CW memory keyer, the IC-756PROII allows external control via the Microphone connector.

Triple Band Stacking Register

Hop around the band with ICOM's exclusive triple-band stacking registers. Each band remembers the last 3 frequencies, mode and other settings used.

Complete CW features

High performance memory keyer

A newly designed memory keyer gives your CW an edge. 4 memory channels are provided and can hold up to 55 characters each. Contents of the memory keyer channels are viewable on the LCD for easy storage and editing. Also, auto-repeat and contest number auto-countup functions are available.

From automatic antenna selection to the high-speed auto- antenna tuner, changing bands and antennas is as simple as pushing one button. The ATU remembers the last tuning combination used in the selected band, allowing quick band hopping from 160-6 meters. The IC-756PROII has an antenna switch for up to 3 RX and 2 TX antennas. This antenna management systems included a separate RX antenna connector for receive only antennas like your favorite wire or beverage antenna.
