Isolating Input and Output Failures
If all RF diagnostic tests pass, there could still be a problem with the input and
output paths (including reverse-power and overpower protection). Run the
Miscellaneous Diagnostics test titled RF Input Output Test. A failure indicates
that the input section or front-panel connection is faulty.
