The\u00a0Sunair 8220WB 1 kW HF Transmitter, Wideband operates continuously (100% duty)<\/a>\u00a0<\/strong>and consists of the Sunair RT-8500WB Software-Defined Wideband Next Generation HF SSB\/ISB Transceiver, the F-9810 Post-selector, and the LPA-8220 1-kW Power Amplifier, all mounted on a pre-wired custom cabinet for ease of installation and maintenance.
\nThe RT-8500WB transceiver uses software-defined digital signal processing (DSP) technology, which supports the latest developments in high-speed waveform processing. This technology enhances the functionality of the CPU as well as the Synthesizer, Digital Audio, and Digital IF stages. It operates in USB, LSB, ISB, AMe, FMn, CW, and 48-kHz WBHF. The audio interface supports analog or VoIP connections, while the CPU allows for remote control and programming via Ethernet or serial port.
\nThe RT-8500WB transceiver incorporates a next generation 48-kHz Wideband capable HF Modem and ALE controller. This provides a purpose-built standalone hardware platform for strategic and maritime WBHF Beyond Line-of-Sight (BLOS) and Line-of-Sight (LOS) radio communications. The Wideband Automatic Link Establishment (WALE) or Fourth Generation (4G ALE) controller compliant with MIL-STD-188-141D Appendix G is used in setting up and managing WBHF links. The WALE controller provides fast and robust link setups by dynamically adapting the bandwidth and frequency
\noffset of wideband channels to avoid interference and optimize throughput. The WALE link setup controller also provides inter-operation with second generation ALE (2G ALE) and third generation ALE (3G ALE\/FLSU). WALE supports (as 3G ALE) both synchronous and asynchronous modes.
\nAdvanced built-in-test (BITE) capability reports the status of the\u00a0Sunair 8220WB 1 kW HF Transmitter, Wideband<\/a><\/strong> down to the Lowest Replaceable Unit (LRU) level providing English messages on the display of the radio, and then to a remote site when configured. Individual LRU fault indication and the system\u2019s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. These high-performing niche products are in daily service as integral components of critical strategic communications solutions for leading defense, peacekeeping, and aviation agencies around the world.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
