ICOM IC-R75 USB/LSB/CW/RTTY/AM/FM 0.03-60Mhz Desktop Radio Receiver

Product code: ICOM IC-R75

The Icom IC-R75 receiver continues the proud tradition of the earlier R70 and R71A models. With full coverage from 30 kHz to 60 MHz; all longwave, medium wave and shortwave frequencies are supported plus extended coverage to include the 6 meter amateur band. Some of innovative features of the R75 include: FM Mode Detection (but not the FM broadcast band), Twin Passband Tuning, Two Level Preamp, 99 Alphanumeric Memories, four Scan Modes, Noise Blanker, Selectable AGC (FAST/SLOW/OFF), Clock-Timer, Squelch, Attenuator and backlit LCD display. Tuning may be selected at 1 Hz or 10 Hz steps plus there is a 1 MHz quick tuning step plus tuning Lock. The R75 exhibits very impressive and very linear sensitivity throughout shortwave. Superior dynamic range insures the handling of both weak and strong signals. The front-firing speaker provides solid, clear audio. The back panel includes a Record Output jack and Tape Recorder Activation jack (both 3.5mm mini). There are both Hi-Z and Lo-Z antenna inputs.

The IC-R75 comes with:

HF/50MHz coverage and innovative features...

High sensitivity receiver circuit

Receive sensitivity characteristics example

Icom’s wide-band technology provides a consistent receiver sensitivity over the entire receive frequency range: 0.03–60MHz*1. The IC-R75 makes it easy to receive communications world wide.

*1 Guaranteed 0.1-29.99MHz and 50-54MHz only ; Some versions have restricted coverage.

Superior dynamic range

Dynamic range characterisutics example

A wide dynamic range of over 100dB, and a well-designed triple conversion system help minimize image and spurious responses for better signal fidelity.

Twin PBT capability

The twin PBT (Passband Tuning) function electronically narrows or moves the IF passband widths at two stages to avoid or remove interfering signals.

Flexible filter selection

Filter Construction

Up to two optional filters*2 can be installed, providing flexible bandwidth selection.

*2 One each for 9MHz and 455kHz IF stage.

DSP capability

With the optional UT-106 DSP unit installed,* you can activate a noise reduction function that improves the S/N ratio. And the automatic notch filter automatically cuts interference from carriers. These digital functions pull desired signals out of noise, and provide superior receive quality.

* Already installed with some versions.

Front mounted loud speaker

The IC-R75 has the speaker mounted on the front panel. With the speaker facing the operator, audio is heard clearly and directly while operating.

Simple operation

The function display has a large alphanumeric readout that indicates up to 8-character memory names for easy recognition. Oftenused keys such as mode switches, filter and tuning step have been placed above the tuning dial for easy access.
