Nyet Comrade, that's a fact: Perhaps you can get out 40 words per minute with no errors using 2 fingers on your desktop keyboard at work - but you really gotta be fast. 40 WPM is really the low end of the upper speeds seen in regular use. I looked up the world speed record and it's a little over 75 WPM. There are many who cannot type with 10 fingers at that speed.

It is in the tens of millions of miles per watt. But that's a different topic, since modern digital techniques exceed that by nature of their coding gain.

Well, I most certainly disagree with several of your statements, but that one I don't think anyone can dispute. Shannon - a mathematician! - was simply brilliant.

Oh, and to amplify Al's comments: I don't know why he needs so many transistors (three or four! ), I can send code using a battery and some wire, maybe some carbon to simplify things. Not legal any more, because it pollutes the radio spectrum badly, but in a pinch, any electrical source and some conductors will allow me to send a signal several hundred miles.

Oh, and EricH - it is best to write Morse code like it sounds: "Dididit dah dah dah dididit" for SOS - your brain doesn't hear the tones as 'dot' and 'dash' but as dit and dah, writing it like it sounds helps increase understanding. Just a trick I've learned.

PS: FIRSTers, if there's somehting you didn't understand - google it. You might be surprised.
