thx for your suggestions
i`f been playing the hole evening now
In the command i`f changed the following:
the -l 2 an changed the wbfm to am
as you suggested.
Tomorrow the airport wil be open and than i wil hear the sound.
i hope it will sound better. The noise is still there but not so hard anymore.
sudo rtl_fm -M am -f 118.7M -r 22000 -p 50 -l 2 | lame -r -s 22.0 -m m - - | ezstream -c ezstream.xml
Is there a commando to let the scanning and streaming going and exits the command prompt?
