Hi Skipp,   > And we've seen some sloppy engineering in the > design of the audio and limiter circuits. What you're saying here Bob... is that you've owned at least one Icom IC-230 at some time in the past.  :-)   While the mobiles probably suffer from the same kind of engineering shortcuts, I was referring to the 'exciter wars' investigation..  :-)   The GE FM exciter showed distortion from a "soft" diode clipping circuit, and the PM exciter's "blob" showed interaction between filters because a high impedance stage drove a low impedance one. Also, the PM's response rolled off due to an RC decoupling circuit that should have been a choke instead.   Speaking of exciter wars, we're still looking for a schematic of a PL19A130605G4 channel element that shows component values. Can anyone help?   Thanks, Bob Yahoo!
