Really, to all you guys:
There is sense, and there is non-sense here... Never doubted you ALL had the the sense, just pleased you can enjoy a bit of non-sense... And, yes, the first time I found out I had to increase effective radiated power by a factor of 4 to achieve a factor of 2 on someones S-Meter--I was disapointed--not sure I have fully recoved from the meaning of that to this very day--frankly, I expected more... I expect if I consulted a psychiatrist on all this--he would, most likely, chalk it up to "penis envy"... and that is why I have not... grin Warmest regards, John "Roy Lewallen" wrote in message ... Reg Edwards wrote: A transatlantic coaxial cable, 2000 miles long, has an overall attenuation at 5 MHz of around 4000 decibels. . . Just to get a little context here. . . Years ago when I was a little bored, I determined that the ratio of the light output from a common two cell flashlight to the entire light output of the Sun is a mere 280 dB (10^28). So if you attenuate the Sun by 280 dB you get the light of a flashlight beam. Well now, if you took that flashlight beam and attenuated it again by the same amount, then did that again, and again, 14 times altogether, you still wouldn't quite have totaled 4000 dB. It's a staggering number, incomprehensible except by some pretty abstract thinking. It's real, though. I remember reading a paper long ago about transatlantic cables, and those are the numbers they work with. Roy Lewallen, W7EL |
