6.3 BER(Bit Error Rate) is high

Here 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.
