I think the intercept point is independent of the signal spacing, at least up
to
the bandwidth of the filter between the antenna and first active devices or
mixer. Dynamic range is definitely a function of signal spacing. Emphasis
on
"I THINK" by the way! :-)
Anyone know for sure?
In any case, the Omni VI is no slouch in this department! That along with
the very quiet synthesizer make it a desirable rig.
