The ERX 3003 / RX 3003 are the new core units of the well-known and proven HF Radio Series 3000 from Hagenuk Marinekommunikation. The ERX 3003 is designed for semi-duplex voice and data transmission/reception and contains the complete exciter/receiver unit. It reserves space for e.g. multifunction data modem and configurations modules. The RX 3003 uses only the receiver part and is equipped with an additional built-in power supply.
With its outstanding and new RF direct sampling technology, this new radio boosts transceivers / receivers into the new generation of software defined radios (SDR) with 24 kHz wideband capabilities.
Being compliant to air traffic management protocol ED 137 for HF, the radio can easily be integrated into air traffic control systems.
The modular concept of the ERX 3003 allows incremental upgrades. The unit provides facilities for various radio communication applications. Different hardware- and software-based options are available. The equipment is designed to service various kinds of interfaces and hence simplifies integration into complex systems.
Furthermore, the new ERX 3003 is fully compatible with its predecessor ERX 3000. Thus, the TRX 3xxx series is upgradable to HF wideband transceivers.
With the ERX 3003, HMK remains faithful to the logistic concept of minimizing the provision of device-specific spare parts. The construction as well as the internal modules of the ERX 3003 are the same for all 150 W to 10 kW transmitters / transceivers. The stand-alone receiver RX 3003 also features identical modules, however, the transmit function is disabled by its software configuration.
