List of errors found after the final typesetting round (updated 2019-11-24):
You proofread and you proofread and your friends proofread, umpteen times. Still you miss a word here, a comma there, a typo here and there. It is amazing what can escape your gaze. Then you do a last minute addition and another thing slips through.
The best proofread by far was making the Finnish translation: when you have to take your text one sentence at a time and turn it into a meaningful sentence in another language, you really need to read through it. Unfortunately at this point the original English version was already in print. Special mention must also be given to Miles Jiang, who found several errors and misprints during his translation effort for the Chinese edition.
Here are some of the most noteworthy issues found. My apologies for not catching them sooner.
Page 7: Missing word "almost" before "forty years". Thirty-six years is the precise number.
Page 9: Several sources state that Marconi's Wireless Telegraph Company name change happened already in 1900.
Page 12: "Tesla" became an official unit in 1954, not in 1956 as stated.
Page 20: Marconi's experiments over the English Channel were done in 1899, not 1897.
Page 29: Omitted mentioning Hedy Lamarr in the discussion about frequency hopping. Fixed in this blog entry.

Page 33: Fessenden worked at the Western University of Pennsylvania.
Page 45: "HD radio" is accidentally referred to as "HD audio". Twice.
Pages 49 and 96: Word "employer" used instead of the right one, "employee".
Page 74: Typos: "EPIRB" referred to as "EPIB" (twice), and "PLB" as "PAB".
Page 76: I cut corners and did not get into details of Sidereal Day. The orbit time for a geostationary orbit is actually 23 hours, 56 minutes and 4.0905 seconds, but why this is different from the "expected" 24-hour day would break the flow of the base story. My apologies to the more scientifically-minded readers. More info in this blog entry.
Page 82: Kosmos-Iridium collision happened in 2009, not in 2001.
Page 87: The Improved Mobile Telephone Service (IMTS) was introduced already a year earlier (1964).
Page 96: Typo: The text refers to "DPA" instead of the correct "PDA".
Page 97: Typo: missing apostrophe in "Microsoft Windows' C++ development environment".
Page 100: The most embarrassing of them all, for a Finn: misspelled "Linus Torvalds" due to a last minute change. For someone who's actively been using Linux for almost two decades, this was bad. I'm sorry.
Page 100: Typo: "Microsoft Phone" should naturally be "Windows Phone".
Page 130: Naturally the discussion is about electromagnetic fields, not magnetic fields in sentence "...a strong magnetic field..."
Page 132: The official name for the 802.11 Wireless LAN Working Committee is 802.11 Working Group.

Chapter "Home Sweet Home": Not an error per se, the world just took a different turn while the book printing process was still going on. Details in this blog entry.
Page 163: The Arecibo message was sent in 1974, not 1973.
Page 176: The Soviet Bloc FM band starts from 65.8 MHz, not 65.9 MHz.
