I have noticed since about 15 November 2006, for sure
since 25 November my loopback frequency measurement
values on FO-29 have changed and are more variable. 
Normally my loopback frequencies on FO-29 are stable
at the several hundreds of Hz but lately they are
variable with a peak range of 1.5-kHz--so far.  Now I
know why lately I am getting these loopback frequency
changes from pass-to-pass and day-to-day.  When the
passband is saturated the frequency translation is
non-linear.  Additionally, distortion becomes a
problem for all users when the passband is saturated.
