The first integrated SDR transceiver with 500W power debuts at Hamvention 2025 in Dayton
Austin, Texas - May 16, 2025:
Company FlexRadio Systems, líder vo vysokovýkonných riešeniach softvérovo definovaného rádia (SDR), s hrdosťou oznamuje rad Aurora™ - a brand new HF/6m transceiver family that brings the first truly integrated 500W SDR transmitter in the world. The Aurora series creates a new category in amateur radio, removing the traditional boundaries between the transceiver, the amplifier, the tuner and the power supply.
Designed for modern operators, the Aurora series offers exceptional RF performance in an extremely compact design - utilizing cutting-edge technology with high efficiency that produces more power with less weight, lower temperature, and significantly reduced power requirements.
Efficiency like you've never experienced: 500W in one box
Srdcom Aurory je revolučný 500W vysielací modul s účinnosťou až 90 % – čo je výrazný pokrok oproti konvenčným MOSFET a LDMOS designs, which typically only achieve 40-60%. The result is less heat dissipation, a smaller heatsink, and a much lighter radio. The entire 500W transmitter fits in the same size as traditional 100W PA systems and runs cool enough to use the same heatsink design as the FLEX-8000 model.
This level of integration means that operators no longer need external amplifiers, tuners, or heavy AC/DC power supplies.
The Aurora series includes everything needed in one case - power supply, automatic antenna tuner, and 500W transmitter - with a standard IEC AC connector for voltage 80–264V.
Platform, not just a radio
Rad Aurora je exkluzívna platforma spoločnosti FlexRadio - its 500W transmitter is not an external amplifier and nedá sa kombinovať s inými transceivermi. Namiesto toho je úzko integrovaný s architektúrou SmartSDR, čo umožňuje precíznu kontrolu, inteligentné zvládanie záťaže a bezproblémový užívateľský zážitok.
Všetky modely Aurory poskytujú 500W na HF pásmach (200W na 6m) and include an integrated ATU. Versions are available M a bez-M:
- AU-510 / AU-510M - models with one SCU
- AU-520 / AU-520M - models with two SCU
Innovation for every operator - FlexRadio Aurora
The Aurora series was designed with an emphasis on flexibility, making it ideal for various types of operators:
- Domáce stanice will appreciate fewer cables and a cleaner layout.
- Portabloví operátori získajú jednoboxové riešenie with significantly reduced size and weight - a 500W radio that you can carry.
- DX expedície can minimize logistics, fuel, and generator requirements.
- Remote operátori will simplify station and infrastructure control thanks to all-in-one solutions.
Significant specifications and comparisons
Compared to a traditional 500W station with external components:
- Hmotnosť: Aurora váži len 8 kg oproti 21 kg with equivalent setups.
- Napájanie: Vyžaduje menej ako polovicu of AC power consumption.
- Teplo: Vytvára len 125W odpadového tepla – čo je o 84 % menej than conventional systems.
Rad Aurora pretvára význam „QRO“ - for experienced DXers as well as new portable operators.
