I hear a burbling sound on some
stations.
• DAB like other digital media is good at
producing quality audio from a low level signal,
however if this signal, level is too low a
“burbling” sound can sometimes be heard.
• To reduce this try repositioning your antenna
to gain maximum signal strength, alternatively
available to the TU-1800DAB.
