Downconverter 455KHz - 12KHz.
Down-converter for DRM signals reception. To be used with popular HF receivers. The HF receiver’s IF out is connected with the down-converter and the output of down-converter is connected with the P.C. sound card. Thanks to a freeware software voice, texts and data are made available on the P.C. The board is compatible with DREAM DRM software available in Internet (the software is not included with the board).
