Icom IC-R9500 Base Station Communications Receiver (discontinued)

Further details of Icom IC-R9500 Base Station Communications Receiver

• 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.
• 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).
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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).
• 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 the 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.
• 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.
• 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.
• The IC-R9500 has built-in FSK demodulator and decoder.
• 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.
• 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.
• 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.
• 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.
• The built-in synthesizer announces the receiving frequency, mode and signal strength in English.
• The IC-R9500 has a USB connector for connecting external USB memory or other USB devices. Received audio and the receiver configuration files can be imported and exported to a PC. Firmware upgrades are also possible via USB memory.
