EMRFD Chapter 1 Errata.
p1.3, left col, very top: replace "Reactance
is little consequence..." with "Reactance is of little
consequence..." (9Dec03)
p1.5, left col, 0.7 inches down from top of text: change
"viable" to "important" (26Mar03)
p1.7,
right col, 1.8 inches down from top of text: change
"know" to "known" (24Feb03)
p1.8, right
col, 5.6 inches down from top of text: change "a an
inductor" to "an inductor" (24Feb03)
p1.11, middle col, 0.8 inch down
from text top. replace "indictor" with "indicator"
(9Dec03)
p1.11, Fig. 1.16.
In figure, fix spelling. "Course" becomes "Coarse."
New figure shown below: (11June03)
Fig. 1.16.
p1,14, left col, 2.2 inches down
from text top. The 7812 has a max I of 1
A and not 0.5 A. (16June03)
p1.17, Fig 1.31. There is
a missing ground symbol in the figure. It should
be:
(5Dec03)
p1.18, column 3, 3.6 inches down from text
top. Replace the sentence "We measured
L1 and set the value that desired." with "The
L-network design (see section 3.6) produced values of 1.97
uH and 197 pF. We wound an inductor on a toroid and then
measured inductance,
spreading or compressing turns slightly to produce the desired
value." (19Aug03)
p1.18, modify Fig 1.33 to emphasize
R1 discussed in text. Shown below
Fig 1.33. (same
caption)

p1.19, left col, 1.8 inches
up from bottom of text, should read "...increase power by about
10 dB to ..." (26Mar03)
p1.19 and 1.21, Fig 1.35 and Fig 1.39. Change
Q5 from the discontinued 2N5321 to a MJE181. Mount transistor
with an insulated spacer so circuit board serves as a heat sink. (Note:
The board alone was not an adequate heat sink and the transistor
started to increase in temperature. It was good enough for testing.
A small heat sink would be useful. Efficiency is worse with
the MJE181 than it was with the 2N5321.) (25Jan05)(29Jan06)
p1.21, Fig 1.40. Pin 6 of the 555
IC should be connected to pin 2. Hence,

p1.23, Ref. 1. Roger
was honored, but it's W. Hayward and D. DeMaw. (24Feb03)
