This unit induces Negative Peak Cilpping in the transmitted and received signal. It appears to be a fault in the "Threshold Setting" of one of the Analog to Digital Converters. The only way to overcome the problem is to use your "Analog Signal", that you wish to transmit, and use it to modulate a Subcarrier. On the receive end you then use a Subcarrier Demodulator to recover your Analog Signal.
