welle.io

This repository contains the implementation of a simple DAB/DAB+ receiver. It is fork from dab-rpi and sdr-j-dab which is now qt-dab https://github.com/JvanKatwijk/qt-dab.

The receiver supports terrestrial DAB and DAB+ reception with as input the sample stream from a airspy, a rtl_sdr, a rtl_tcp server or a I/Q RAW file (for developers).

For a user oriented documentation please see the project site https://www.welle.io.

Usage

The command line parameter are:

Parameter	Description
h	Show help
v	Show version
D	Input device. Possible is: auto (default), airspy, rtl_tcp, rtl_sdr, rawfile
M	DAB mode. Possible is: 1,2,3 or 4, Default: 1
I	rtl_tcp server IP address. Only valid for input rtl_tcp
P	rtl_tcp server IP port. Only valid for input rtl_tcp
F	I/Q RAW file. Only valid for input rawfile.
B	I/Q RAW format. Possible is: u8 (unsigned int 8 bit, qt-dab RAW files), s16le (signed int 16 bit little endian, qt-dab SDR files), default: u8. Only valid for input rawfile.
