The Inrad audio mod and 2.8Khz filters can only improve the Omni6+ to
a limited degree, because the Omni's receive audio is always routed through dsp
and notch filter ic's even when those functions are not engaged. I
proved this point to myself by tapping the product detector audio
directly at U3-6 as an experiment and couldn't believe my ears.
