Superb receiver performance
The IC-R9500 achieves amazing performance by using a D-MOS FET array in the 1st mixer (below 30MHz) and an excellent IMD roofing filter. The IC-R9500 has +40dBm IP3 and 109dB dynamic range at 14.1MHz. IP3 performance is +9.8dBm at 50MHz and +6.2dBm at 620MHz (+5dBm (typical) from 30MHz to 3335MHz).

Five roofing filters
The IC-R9500 has 5 independent roofing filters (240, 50, 15, 6 and 3kHz) for improved selectivity. In congested RF spectrum conditions, it is extremely important to protect against strong in-band signals. The 3kHz roofing filter provides a 130dB (approx.)* blocking dynamic range.
* At 15MHz reception, with 5kHz separation signals.
The IC-R9500 incorporates two independent, 32-bit floating point DSP units, a dedicated DSP unit for receiver functions and another for the spectrum scope. By using the power of two independent DSP units, the radio can respond to operator changes in an instant.
±0.05ppm high frequency stability
The IC-R9500 uses an OCXO (Oven Control Crystal Oscillator) unit which provides ±0.05ppm frequency stability from 0°C to 50°C. The 10MHz reference frequency can either be supplied to or input from external equipment.
Digital IF filter
The digital IF filter* allows the operator to adjust the filter shape (sharp or soft), filter bandwidth, and centre frequency characteristics. The digital twin PBT narrows and shifts the IF passband to efficiently eliminate undesired signals.
* For FM, WFM and P25 mode, the passband
b>Multi function spectrum scope
Using a dedicated DSP unit improves the dynamic range of the spectrum scope. The IC-R9500 has four different spectrum modes such as normal/wide and centre/fixed width. The normal spectrum scope covers a range from ±2.5kHz to ±5MHz, while the wide band spectrum scope* observes up to ±500MHz (±10MHz, ±25MHz, ±50MHz, ±100MHz ±250MHz and ±500MHz selectable). When using the normal spectrum scope, the digital scope’s filter width can vary from 200Hz to 20kHz with a variable sweep speed.
The spectrum scope can also be set to use specific scope edges or to centre the span on the receiving frequency.
The peak search function automatically moves the display marker to the strongest signal on the scope screen. In addition to these features, the scope has 3 levels of attenuation (10dB, 20dB, 30dB).
- Fixed mode: The scope screen does not shift when you change the receiving frequency.
- Centre mode: the scope screen shifts as the receiving frequency moves. The receiving frequency is always centred on the scope screen.
- Wide band scope: Receives up to ±500MHz
- Peak hold function
- Sweep speed/span/filter width setting
- Peak search function
- Mini scope function
* While using the wide band scope function, AF output is muted.
7-inch wide Colour TFT LCD
The large 7-inch wide (800 x 480 pixels) active matrix display delivers quick response time, high resolution and has a wide viewing angle. The multi-function spectrum scope is displayed in vivid colour. The background colour is selectable from black or blue for your preference. In addition, the IC-R9500 has a VGA connector allowing you to connect an external monitor.
S-meter, dBì, dBì(emf) and dBm meter types are selectable in the IC-R9500. The dBì, dBì(emf) and dBm meter have ±3dB of accuracy (10 to 70dBì signal from 100kHz to 3335MHz at 25°C).
The IC-R9500 has a DSP controlled noise blanker that significantly reduces pulse type noise and improves the S/N ratio by removing interfering noise. The noise blanker has two channels with adjustable width and depth parameters. You can use these to target specific noise interference.
The noise reduction function separates signal components from random noise through Digital Signal Processing (DSP) and enhances the signals buried in noise for improved signal readability.
Two-point manual notch filter
The digital manual notch filter has a depth of more than 70dB at two points with adjustable filter width (wide, middle, narrow). This means that two strong beat signals can be eliminated at once even while using the auto notch filter.
Synchronous AM detection
The synchronous AM (S-AM) detection provides less distorted audio than normal diode detection. This mode is useful when fading occurs or signal level is low. The IC-R9500 can recreate the carrier signal exactly by using the DSP. In addition, upper or lower sideband demodulation for S-AM is selectable for eliminating interference from adjacent strong signals.
FSK modulator & decoder
The IC-R9500 has built-in FSK demodulator and decoder.
- Twin peak filter
- Water-fall indicator
- FSK-R mode
- FSK tone and shift frequencies programmable
The IC-R9500 has 10 VFO channels for tuning and storing operating frequencies, mode, filter width and other settings. You can quickly change the operating bands with the 10- keypad. When the VFO is changed, the settings are automatically stored in that VFO channel.
A total of 1220 memory channels
The IC-R9500 has a total of 1220 memory channels. Store frequencies, modes, filter width and tuning steps. Memory channels are grouped into 10 memory banks. By connecting to a USB keyboard, you can edit memory contents directly.
- 1000ch regular memory channels
- 20ch scan edge channels
- 100 auto memory write channels
- 100 memory scan skip channels
Numerous scanning functions (are available) to search for desired stations to make operation easier. The IC-R9500 scans 40 channels per second in memory scan mode.

- Program scan
- Fine program scan
- Priority scan
- Selected mode memory scan

The built-in synthesizer announces the receiving frequency, mode and signal strength in English.
Digital voice recorder
The IC-R9500 has two types of digital voice recorders. One is the regular recorder, recording for long periods in “WAV” format into the built-in CF memory or an external USB memory. The sampling rate is variable from 8kHz (SQ1) to 48kHz (SHQ). In SQ1 mode, up to 130 minutes (approx.) of recorded audio can be stored into the CF memory. The other recorder is the short voice recorder, which saves the previous 15 seconds of radio audio into RAM, allowing you to play back the audio instantly.
The IC-R9500 has a USB connector for connecting an external USB memory or other USB devices. Received audio and configuration files can be imported and exported to a PC. Firmware upgrade is also possible via USB memory.
