RTLSDR-Airband or rtl_airband receives analog radio voice channels and produces audio streams which can be routed to various outputs.


Broadcastify Fully Supports RTLSDR-Airband or rtl_airband.

RTLSDR-Airband or rtl_airband - User's Manual:

RTLSDR-Airband or rtl_airband support multiple frequency channel scanning features.

Here is a custom rtl-airband.conf config file for Broadcastify server and local Icecast server if you have it setup in your Raspberry Pi unit.

Else you can set "disable = true;" if you do not need that section profile enabled. Otherwise set "disabled = false;" if you need that section profile to be enabled for active usage.

# The program may exit only due to startup failure (eg. misconfiguration)
# or due to failure of all SDR devices (eg. disconnection). In either case,
# there is no point to restart it, because it would fail once again.
