Take your DXing to the Next Level +30dBm-class Third-order Intercept Point
+30dBm IP3*
Using receiver design techniques introduced
in the IC-7800, Icom’s engineering team
focused on delivering distortion-free, highdynamicrange. To achieve this goal, Icom
used higher-grade omponents in vital receiver
sections of the IC-756PROIII.
Two newly designed preamplifiers
To minimize distortion and maximize dynamicrange, the IC-756PROIII preamplifiers use the same basic circuit design as the IC-7800
preamplifiers. Preamp-1 is a noiseless feedback
design, with push-pull amplifiers.
Preamp-2 uses bipolar transistors for higher
gain. It is ideal for using separate low-efficiency
receiving antennas such as small
loops or Beverages.
Real-time spectrum scope with mini-scope function
The real-time spectrum scope is now an
indispensable tool for top performing HF
radios. The IC-756PROIII’s spectrum scope
adds a mini-scope function. The mini-scope
allows you to monitor the scope screen while
you use other function menus. For example,
you can monitor
the scope screen
even while you are
changing the IF
filter shape and
passband width.
Adjustable SSB transmit BW
With the flexible DSP-based waveform shaping, you can tailor your transmit audio quality to suit your operating style. The SSB transmit bandwidth is selectable from 100, 300 and 500Hz on the low end, and 2500, 2700 and 2900Hz on the high end respectively. 3 sets of high and low ombinations can be stored in memory.
32-bit floating point DSP & 24-bit AD/DA converters
The heart of the IC-756PROIII is the proven combination of the 32-bit floating point DSP and 24-bit AD/DA converters. This powerful combination supports the many digital processing features of the IC-756PROIII.
Sharp and soft filter shapes
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.
AGC loop management
The digital IF filter, manual notch filter etc.
are adopted in the AGC loop, and controlled
by the DSP. This system removes blocking
by extremely strong adjacent signals outside
of filter passbands. Even very weak signals
between crowded strong signals can be
clearly extracted from the noise.
Eight-channel RTTY TX memory
The built-in RTTY demodulator and decoder allow you to check the callsign of the station on the air instantly. The IC-756PROIII has 8 channels of RTTY transmit memory. You can edit and send up to a 62 character message for each memory channel without a PC or other external unit.
