WiNRADiO WR-65DDCe HF-VUHF Receiver

The WiNRADiO WR-G65DDC 'EXCALIBUR Sigma' is a top performance, direct-sampling, software-defined, wide-band, two-in-one HF/VHF receiver with two frequency ranges from 1 kHz to 88 MHz and from 118 MHz to 190 MHz. The receiver has two independent and mutually exclusive inputs, one per each range. It includes a real-time 88 MHz wide spectrum analyzer (72 MHz in VHF range) and up to 64 MHz wide instantaneous bandwidth available for recording, demodulation and further digital processing.

The receiver's superior performance results from its innovative, direct-sampling, digital down-conversion architecture along with the use of leading-edge components and design concepts. These all result in excellent sensitivity, selectivity and dynamic range, highly accurate and stable tuning, and perfect demodulation. These key features create a receiver in a class of its own, with wide application potential, with many operational and instrumentation features not usually found on receivers of any price category.

The entire 64 MHz DDC (digitally down-converted) bandwidth is available for recording and demodulation, and ideal for hopping frequencies analysis. Three demodulators allow the simultaneous reception and decoding of radio signals within the entire band.

The receiver's robust front-end is equipped with an ultra-high-linearity amplifier which results in exceptional strong-signal performance while at the same time offering excellent sensitivity.

The WR-G65DDCe also features optional external reference clock inputs and outputs, coherence clock input, 1PPS pulse input as well as an FPGA interface, ready for phase-coherent system configurations such as in high performance interferometer direction finding applications. In addition, stereo analog output is also possible, as well as wide audio (10 Hz-150 kHz). The special data port offers numerous possibilities which include GPIO (general purpose I/O), HSP (high speed data output), or traditional RS232 interface.

The receiver interfaces to a Windows-compatible PC via USB 3.0, or 1 Gb Ethernet LAN port with PoE (Power over Ethernet functionality according to IEEE 802.3at standard).

The receiver is very well shielded against interference, making it possible to operate in a noisy computer environment. Its modest power requirements are less than 12 watts. While connected via LAN interface, thanks to PoE built-in functionality, the receiver can be operated and powered via a long Ethernet cable connection.
