11.3 BER(Bit Error Rate) is high



There are co-channel signal interference nearby, please be away from interference sources or modify frequency and
channel to avoid interference;



Poor power supply may cause messy code. Make sure that the power supply is reliable.



The extension line and feeder quality are poor or too long, so the bit error rate is high;
