Verify that the 3-stage switch and its
jumpers are properly and firmly installed.
Verify that any unused RF ports are
properly terminated.
Use a spectrum analyzer to look at the
reverse RF input signal spectral quality at
each reverse input test point and compare
it to the reverse
RF output signal spectral quality.

Reverse RF signal still low or degraded.
If degradation is generated in the reverse
amplifier, replace the reverse amplifier.
If degradation is generated by the
downstream amplifier reverse RF signal,
troubleshoot the RF amplifier feeding this
station.
Replace the reverse amplifier module.
