with 30 dB gain set on both Tx and Rx. I was getting cluttered overflows and packet received during that time are in error.. Like I'm receiving about a 1000 packet without error and then then system runs into overflow and about then quite a large number of packets are received in error.

Any idea how to avoid these overflows???
