I found I needed to adjust the input to the distribution amp with an

I tuned the channel to the worst channel (five in my case) and then
ran femon.  The number of corrected errors is a very sensitive measure
of how good your signal is (signal strength is a bit random I find).
I adjusted the attenuator for minimum errors.

My worst Mux is Mux A which had channel 5 on it.  I get about 0x900 ==
2300 corrected bit errors per second on it.  It only rarely gets an
uncorrectable error.
