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)
F-9810B PRE-SELECTOR
Sunair F-9810B Pre/Postselector The Sunair F-9810B Pre/Postselector permits operating collocated (co-site) Sunair radios, whether the RT-8500WB Transceiver or any radio of the 9000E Series, on frequencies with as small as a 10% separation. The Sunair F-9810B is controlled by the Sunair radio it serves. As a pre-selector, the F-9810B provides an additional front-end selectivity stage, thus reducing the receiver desensitization and overload that normally occurs in the presence of strong adjacent RF transmissions. As a post-selector, the F-9810B rejects spurious outputs and broadband noise in the transmit signal before it reaches the Sunair LPA power amplifiers, thereby limiting interference to collocated receivers. In transmit mode, the F-9810B operates as postselector on the radio’s low output power path. Because of this, the F-9810B is fully operational as postselector with an RT- 8500WB regardless of whether the transceiver is driving the LPA-8200 at 100 mW or operating at its full 125-W output. A separate transmit antenna port provides the flexibility of using either a single antenna for transmission and reception or separate transmit and receive antennas. In addition, the keyline over coax feature prevents damage to the unit from high power RF transmission by reducing the control time delay of transmit-to-receive switching. The F-9810B offers a selectivity of 35 dB minimum (±10%), 40 dB typical, from the nominal tune frequency, with an ultimate rejection of 70 dB minimum. The unit tunes in 10 Hz increments, and tuning time is 10 ms maximum, making the F-9810B suitable for ALE applications. Furthermore, the F-9810B offers two levels of gain. The Pre/Postselector’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. F-9810B • Improved co-site performance • 40 dB typical, 70 dB maximum attenuation • Selectable gain • Individual transmit and receive antenna ports • Automatic tracking 10 ms tuning • Automatic RF overload protection • Automatic by-pass

In this setting, it also supports Automatic Link Establishment (ALE) as an external option in accordance with MIL-STD-188-141 A/B/C, FS1045A, and S4538 as well as STANAG 4444. The radio’s advanced built-in-test (BITE) capability provides feedback to the lowest replaceable unit (LRU) level by means of test result messages in English on the display as well as LED indications. The R-8400 can operate from both ac and dc voltage sources with automatic changeover if one of them fails. Its internal power supply provides energy to the internal modules as well as to external accessories. The R-8400’s intuitive modular design allows for ease of maintenance, expansion, and upgrade throughout the equipment life cycle at minimal expense. Its construction minimizes undesirable RFI and EMC effects by using multiple layers of shielding as well as filtering and protection on the individual control lines.

Wideband 1kW HF transmitters

Wideband 1kW HF transmitters in 2026 are primarily solid-state, software-defined systems designed for high-speed data and mission-critical communications. These systems prioritize high data throughput, modularity, and compliance with military wideband standards like MIL-STD-188-110D

Key Technological Trends:
  • Modular Redundancy: Multiple internal amplifier modules ensure “graceful degradation,” allowing the transmitter to remain on-air at reduced power (typically 500W) during a partial failure.
  • Digital Pre-Distortion (DPD): Modern exciters use DPD to improve linearity and reduce intermodulation distortion, critical for wideband data waveforms.
  • IP Integration: Support for VoIP (ED137B/C) and remote SNMP monitoring allows these transmitters to be integrated into modern digital command centers.
