Different transmit and receive frequencies are being used. The levels between the transceiver and the TNC/MCP are incorrect. Your transmitted signal or the incoming receive signal is too weak. The TX delay time parameter in your TNC/MCP was incorrectly set. 1 Re-check all connections using this manual, your TNC/MCP manual, and your computer hardware manual as references. 2 Confirm that the RIT and XIT functions are switched OFF.
