Two notch filters with an attenuation of 70 dB can be inserted and positioned in order to suppress interference, this manual action is added to the auto-notch function. The final selectivity is instead determined by the digital IF filter characterized by an excellent form factor, of course the bandwidth can be adapted continuously according to the needs.

There are five filters in the first IF (roofing filters) that depending on the operating mode can be selected between the values of 3, 5, 15, 50 and 240 kHz. The positioning function on the peak signal is also available. The possibility of adjusting the excursion limits or centering it on the reception frequency has also been provided. In the panoramic form, on the other hand, the radio-propagation situation can be determined as well as the evolution in a wide band. In normal form the excursion can be set in the range between ± 2.5 kHz and ± 5 MHz, this allows to observe in detail the signal even if close to stronger emissions. The LCD display offers indeed a selectable view in two modes. It incorporates two 32-bit processors (DSP), one employed in the receiver circuit and the other for the spectrum analyzer function. The ICOM IC-R9500 is an wide-band receiver in conventional technology with regard to the frequency conversion structure while it is digital in the last IF for filtering, demodulation and signal processing. For specific band segments in 30~3335 MHz.This parameter, not in official data, was obtained with direct tests.Bandwidth free-defined for CW / SSB / FSK modes.For P25 mode the optional UT-122 unit is request.± 0.05ppm with temperature from 0☌ to +50☌ after 5' warm-up Reference market : professional / amateur-radioĬW / LSB / USB / AM / AM-S / FSK / FM / WFM / P25 Ideated in Japan, year of introduction 2006.
