Icom: IC-R75

The IC-R75 covers a frequency range that’s wider than
other HF receivers; 0.03–60.000000 MHz*.
This wide frequency coverage allows you to listen to a variety of
communications including marine communications, amateur radio, short wave
radio broadcasts and more.
*Guaranteed 0.1–29.99 MHz and 50–54 MHz only
Icom’s latest wide band technology provides highly stable receive sensitivity over the entire receive frequency range. The IC-R75 makes it easy to catch communications world wide.
A wide dynamic range of more than 100 dB*1,
104.5 dB*2 for 14 MHz band,
102.5 dB*2 for 50 MHz band, and a well-designed triple conversion system help
minimize image and spurious responses for better signal fidelity.
*1 Not guaranteed.
*2 Not guaranteed; When PREAMP OFF; CW narrow 500 Hz bandwidth; 100
kHz channel spacing
The PBT (pass band tuning) function narrows and moves the IF pass band at two stages to efficiently eliminate interfering signals.
DSP (Digital Signal Processor) filtering in the AF stage is
available with the optional UT- 106 DSP UNIT*.
The DSP provides the following functions:
* Already installed with some versions
Pulls desired AF signals from noise. Outstanding S/N ratio is achieved, providing clean audio in SSB, AM and FM. Pull weak signals right out of the noise.
This automatically minimizes beat signals and protects the receive signal. Also, the notch frequency is automatically adjusted to follow interfering beat signals—reducing interference from RTTY signals during SSB operation for example.
Unlike many other HF/50 MHz receivers there is no need to install an additional unit for FM mode reception on the 29 and 50 MHz bands.
Up to two optional filters*
can be installed, providing flexible band width selection and filter
combinations.
*One each for 9 MHz and 455 kHz IF stage.
The function display has an alphanumeric readout that indicates up to 8-character memory names for easy recognition.
The RF gain and/or squelch control can be set to the [SQL] control in set mode to match your operating preference.
