Basic PerformanceWideband coverage

The IC-R9500 covers 0.005-3335MHz in SSB, AM, FM (WFM), CW, FSK and P25* modes.
It is suitable for a wide variety of radio monitoring and listening
activities.
* Optional UT-122 digital unit is required.
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 very crowded 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.

[image: Dual DSP Units]
Dual DSP

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 center 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 width is fixed.

Spectrum ScopeMulti 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 center/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 center 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).
* While using the wide band scope function, AF output is muted.

   - Fixed mode ... the scope screen does not shift when you change the
   receiving frequency.
   - Center mode ... the scope screen shifts as the receiving frequency
   moves. The receiving frequency is always centered on the scope screen.
   - Wide band scope receives up to ±500MHz.
   - Sweep speed/span/ filter width setting
   - Peak search function
   - Peak hold function
   - Attenuator
   - Mini scope function

Functions7-inch wide color TFT LCD

The large 7-inch wide (800 × 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 color. The background
color 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.

Multiple RSSI

S-meter, dBµ, dBµ(emf) and dBm meter types are selectable in the IC-R9500.
The dBµ, dBµ(emf) and dBm meter have ±3dB of accuracy (10 to 70dBµ signal
from 100kHz to 3335MHz at 25°C).

Noise blanker

The IC-R9500 has the 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 the specific noise interference.
Two-point manual notch filter

[image: Manual notch filter characteristics]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 distor ted 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 inter ference 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

10 VFOs

The IC-R9500 has 10 VFO channels for tuning and storing operating
frequencies, mode, filter width and other settings. For example, use VFO-1
for the 7MHz band, VFO-2 for the VHF marine band,VFO-3 for the 1200MHz
band, etc. 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

[image: Memory setting example]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

Digital voice recorder

[image: Voice recorder setting example]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 shor t voice recorder, which saves
the previous 15 seconds of radio audio into RAM, allowing you to play back
the audio instantly.
Multi-scan functions

Numerous scanning functions to search for desired stations are available to
make operation easier. The
IC-R9500 scans 40 channels per second in memory scan mode.

   - Memory scan
   - Program scan
   - Fine program scan
