reception frequencies are
being used.
3 The levels between the
transceiver and the TNC/
MCP are incorrect.
4 Your transmitted signal or
the incoming receive signal
is too weak.
5 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 Confi rm that the RIT and XIT functions are
switched OFF. Confi rm that you are not
