    Be aware that the code in the bat-detector also uses //try to avoid interrupts as they can (possibly ?) interfere during recording #define ENCODER_DO_NOT_USE_INTERRUPTS

    Thats indeed special, if you try to use the encoder library to do the same does it still work ? THis is the library https://www.pjrc.com/teensy/td_libs_Encoder.html regards Cor

    Nothing special, just use any setting you wish. Recording is ment to save raw data for later analysis. And like stated using 44Khz SR is not at all effective for bats. You should use at least 96Khz (for bats that dont...

    Be aware that recording will switch to heterodyne mode as we cannot heavily process the incoming raw data at the same time. And using SR 44Khz will not record bats as you can guess

    The SD should be from a good type, I think Frank DD4WH has even tested the effect of lesser quality SDcards. I am using a toshiba Exceria 16Gb that works as planned.

    Hi, Good to hear that. If you have all buttons installed you can select the "waterfall" by pressing the LEFT microbutton, that allows you to step through the 3 modes of display (spectrum, waterfall, none).
