Note
The DC-to-daylight R9500 was introduced in 2007 as the successor to the R9000. It represents a significant technological leap, transitioning from the analog-heavy architecture of the 9000 series to a dual-DSP (Digital Signal Processing) system.
In enthusiast circles, the R9500 is often praised for its "flywheel" VFO feel and professional build quality, including a heavy aluminum chassis. However, it is also noted for having a power supply that runs quite hot and is somewhat prone to failure if not well-ventilated—a common discussion point for those maintaining these units today.
Features
– Frequency Coverage: It covers a continuous range from 5 kHz to 3335 MHz (3.3 GHz), extending significantly beyond the 2 GHz limit of the R9000 series.
– Dynamic Range & IP3: The receiver achieves a +40 dBm 3rd-order intercept point (IP3) and a 109 dB dynamic range at 14.1 MHz.
– Dual DSP Units: It utilizes two independent 32-bit floating-point DSPs—one dedicated to the receiver functions and another specifically for the high-speed spectrum scope.
– Frequency Stability: It uses an Oven Controlled Crystal Oscillator (OCXO) providing ±0.05 ppm stability.
– 7-inch Color TFT Display: Replaces the CRT (R9000) or smaller LCD (R9000L). It supports multiple spectrum scope modes (normal/wide and center/fixed) and can display a waterfall indicator.
– Five Roofing Filters: Features independent roofing filters at 240, 50, 15, 6, and 3 kHz to provide superior selectivity in crowded RF environments.
– Digital Recorder: Includes a built-in digital voice recorder that can save audio in WAV format to an internal Compact Flash (CF) card or an external USB drive.
– Reception Modes: Supports SSB, CW, FSK, AM, FM, WFM, and optional APCO P25 (with the UT-122 digital unit).
– Connectivity: Modernized for its era with a USB port (for keyboard and storage), an Ethernet port for remote control, and a VGA output for an external monitor.
