Errata, Chapter 12, EMRFD
 (5May11)

p12.8, text 1.2 inch down from top of text.   Replace "see Chapter 4" with "see Chapter 6."    (5May11)

p12.32, Fig 12.43.   This is a parts layout for the receiver system of Fig 12.40.   Q4 should be rotated by 180 degrees.    The correct layout can be seen in the photo of the board in the upper right corner of the page.  (13March08)
p12.32, Fig 12.43.   Rotate Q1, Q2, and Q3, as well as Q4.   Q5 and Q6 are OK.  This impacts the figure, but not the layout, for the parts were symmetrical.  (22Aug9)    

p12.43, Fig 12.73.   A new schematic was drafted that should be easier to read.
