WiNRADiO G39DDC

WiNRADiO G39DDC HF/VHF/UHF RX

The WiNRADiO WR-G39DDCi 'EXCELSIOR' is a high-performance HF/VHF/UHF/SHF software-defined receiver with a frequency range from 9 kHz to 3500 MHz, with two independent channels of 4&3 MHz wide instantaneous bandwidth available for recording and further digital processing, plus a 16 MHz wide real-time spectrum analyzer.

These receivers offer a flexible SDR architecture, respectable dynamic range, high sensitivity and scanning speed, fulfilling multiple roles of monitoring, surveillance, fast-search and measuring receivers, with many operational and instrumentation features not usually found on receivers of any price category.

  • High sensitivity
  • Audio and DDC recorder
  • Networking version of application software available
  • USB 2.0 interface
  • No attenuator on VHF/UHF (I had to add an FM-BC and DAB filter to my setup)
  • go2signals support
