Why re-invent the wheel when all you have to do is read this web page from the Electrostatic Discharge Association to know what is old hat to most competent engineers? http://www.esda.org/basics/part1.cfm -- 73, Cecil http://www.qsl.net/w5dxp |

Do you perform experiments to prove or disprove matters to your satisfaction on everything before accepting it? That takes a very special person to be ultimately skeptical.

I don't see why I should believe what Cecil makes up in his head just because he makes it up in his head. "I can't believe _that_!" said Alice. "Can't you?" the Queen said in a pitying tone. "Try again: draw a long breath, and shut your eyes." Alice laughed. "There's no use trying," she said: "one can't believe impossible things." "I daresay you haven't had much practice," said the Queen. "When I was your age, I always did it for half-an-hour a day. Why, sometimes I've believed as many as six impossible things before breakfast. There goes the shawl again!" Cecil and the White Queen would get along well together. 73, Tom Donaly, KA6RUH |

Not many do. I'm not sure that anyone here believes Cecil just because he is Cecil. I don't. Some times I see him posting his way into some very deep holes... "I can't believe _that_!" said Alice. "Can't you?" the Queen said in a pitying tone. "Try again: draw a long breath, and shut your eyes." Alice laughed. "There's no use trying," she said: "one can't believe impossible things."

Why, sometimes I've believed as many as six impossible things before breakfast. There goes the shawl again!" Cecil and the White Queen would get along well together. 73, Tom Donaly, KA6RUH I am corrected. You both determine everything experimentally and enjoy busting on Cecil. I assumed an "And" situation, while it was actually an "OR" situation.. 8^) - 73 de Mike KB3EIA - |

I don't. Some times I see him posting his way into some very deep holes... that's what i see. he says something controversial, gets challenged, and then scrambles for references. the problem is that many of the references do not directly confirm what he's saying, and a bit of calculation is required. i did some googling, and certainly there are others with Cecil's position.

Rather than rationalize and walk through disagreements step-by-step Cecil prefers to distort and bully. His posting ratio averages 3.3:1, and sometimes reaches over 6:1. |

It is the wannabe gurus who need to discover something original so badly that they are willing to go against the accepted laws of physics. -- 73, Cecil http://www.qsl.net/w5dxp |
