  • Channels: 1 (left)
  • Sample rate: 48 kHz
  • Sample format: 16 bit signed

For example, on an android phone, you can use termux

Record audio

nc -l -u 7355 > sound.raw

Where “7355” is the port specified in the MagicSDR application. After recording, convert the raw data to a wav audio file:

sox -t raw -r 48000 -b 16 -c 1 -L -e signed-integer sound.raw sound.wav

To access the android file system from termux, run:


Decode Morse CW

The multimon-ng utility is used.

nc -l -u 7355 | sox -t raw -esigned-integer -b16 -r 48000 - -esigned-integer -b16 -r 22050 -t raw - | multimon-ng -t raw -a MORSE_CW -
