    Question audio output

    [QUOTE=DD4WH;261776]Hi Rudolf: no, there is no complete schematic / es gibt keinen kompletten Schaltplan. Its the very nature of the project that the Teensy Convolution SDR can cope with every I & Q input from many different frontends and that builders have their own plan of the hardware. But you can find an incomplete suggestion in:

    Hallo Frank,

    and Frohe Ostern !

    I have teensy 3.6 also the Elektor SDR board.
    Do I need to buy audio teensy board, or I can use audio output from elektor sdr?
    Thank you in advance !

    My best 73, de yo2ldk

    You Need additional the teensy audio board, which is use as ADC for the analog I/Q signals from the Elektor SDR.

    ..and from my experience, the Elektor board is not very good, but sufficient for the fist experiments. Just don't expect great results.

    The problem of the Elektor SDR is the noisy op amplifier. An low-noise op as the TS464 or TS974 instead the TS914 gives bettler performance.

    Ich habe den Empfänger zusammengestellt und bin sehr zufrieden. Kompiliert #define HARDWARE_DO7JBH mit den Modulen PCM1808 / PCM5102. Die Lautstärke ändert sich jedoch nicht, wenn der Encoder von 0 bis 100 eingestellt wird. Bitte um Hilfe

    Hallo Frank

    I have put together the receiver and I am very satisfied. Compiles #define HARDWARE_DO7JBH with PCM1808/PCM5102 modules. However, the volume does not change when the encoder is set from 0 to 100. Ask for help
