RCU-8310 RCU
Sunair RCU-8310 Remote Control Unit The Sunair RCU-8310 is a full-function remote control unit, now capable of operating up to eight (8) transceivers, transmitters, or receivers from the 8400 series. The next-generation RCU is equipped with a larger 7-inch TFT display, which is now touchscreen, along with keyboard entry. Its front panel is physically identical to the front panel of the unit it controls. This ensures operational simplicity. The RCU offers a full set of operating modes, including AME, NB-FM, USB, CW, Data, as well as remote control of Automatic Link Establishment (ALE) functions when the RT-8400 is equipped with the internal ALE option. These capabilities match the operating modes available on the radio itself. The RCU-8310 also allows remote operation of Sunair peripheral equipment including the F-9810 PreSelector/Post-Selector, the LPA-8210/8220 Power Amplifiers, and the CU-9125/CU-9150 Antenna Couplers. It is possible to connect the RCU-8310 to the remote radio using RS-232/RS-422 for short distances, Ethernet for longer distances, or leased lines (requires the optional internal FSK modem). Advanced built-in-test (BITE) capability provides feedback to the lowest replaceable unit (LRU) level for both the local RCU as well as the companion 8400 series radio. The remote control’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. ● Remote Control via Serial and Ethernet ● Controls Multiple Radios ● Comprehensive BITE to LRU ● Identical to Radio Front Panel ● Analog or VoIP Audio Interface ● Secure Digital Voice (MELPe S4591)
T-10000 HP Wideband 10kW Transmitter
Sunair T-10000 HP 10kW HF Transmitter The Sunair T-10000 HP 10kW Military HF Transmitter is the hallmark solution for mission critical communications applications requiring reliable coverage. The transmitter system combines solidstate radio and RF power amplification and control technology to produce a fail-safe high power solution that operates in a frequency range of 1.5 MHz to 30 MHz. Maximum power output is 10 kW at 100% duty cycle to facilitate long- range hemispheric communications when coupled with the appropriate antenna. Power is reducible in less than 1 dB steps down to 500 W level. Standard operating voltage is three phase 338 – 458 Vac, 47 to 63 Hz with a modest power requirement of ≤ 35 kVA. The Sunair T-10000 HP is supplied as an integrated system equipped with the Sunair T-8400 Software-Defined Next Generation HF SSB/ISB Transmitter. As part of this system, the amplifier architecture consists of eight IPA- 8210 intermediate power amplifier subsystems that are combined to produce final power output and managed by the Sunair HPAC High Power Amplifier Controller. The HPAC actively monitors system balance and performance, and provides power control and safety shutdown in the event of internal module failure such as power supplies, system failures such as air flow or over temperature or external failures such as high antenna VSWR and short or open circuit. Advanced built-in-test (BITE) capability reports the status of the T-10000 HP down to the Lowest Replaceable Module (LRM) level providing English messages on the HPAC and the T-8400 front panel displays, and then to a remote site when configured. Individual LRM fault indication and the system’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. These highperforming niche products are in daily service as integral components of critical strategic communications solutions for leading defense, peacekeeping, and aviation agencies around the world.
