Got it. Thanks. I never saw on my uBitx
the numbers you reported, but I don't think it is a serious
problem for a barefoot uBitx, which is the main point I was trying
to make. It seemed like the group was spending a lot of energy on
something that is like driving 60 MPH in a 55 zone.

Howard,
The mixer where the spur is generated is the mixer formed by T2/T3
that is about?
28db (after allowing for filter losses and all)? later in the
stream and if that mixer
is overloaded you get the spur.? The driving modulator is then
underdriven.
Work it backward.? If that mixer is overloaded at -7 oir -10DBM
what got to be
happening well before that?? ?And that mixer can easily be driven
to its 1DB
compression or worse without hurting the audio to the ear.
