A possible suggestion

I know nothing about this topic, but don't you think that for all the idiots like me the first paragraph should be somewhat rewritten? A quick suggestion is:

A coherer is a type of radio detector, popular in the earliest days of radio development, beginning around 1890. Coherers, in conjunction with spark-gap transmitters, were the first devices to make radio communication practical. Its defining characteristic is a "light-contact" segment, that is normally a poor electrical conductor, but which undergoes a sudden change in conductivity — usually a marked increase — in response to the increased voltage induced by a received radio signal.

This way, at least by the end of the second sentence, we have an idea of why this is an important concept.... Hayford Peirce 13:52, 12 June 2007 (CDT)

I have reorganized the opening sentences so the first one covers "what it is" and the second reviews "how it works". Please let me know if there are any other parts that need further work to make them understandable for a general audience.Thomas H. White 06:08, 17 June 2007 (CDT)

Tesla

I have heard that Nikola Tesla was in fact the first to introduce both a rotating "coherer" and tuneable circuits; versions of both are incorporated into his patent for a robotic boat which I think well predates Marconi. I know the issue was in the past the subject of controversy; would it it worth mentioning here?

Also, I am very glad to have someone with knowledge of early radio here! If your interest includes early (pre-WWII) televsion systems such as those of Baird and Farnsworth, I'd love to have your input into entries such as John Logie Baird and History of television -- your technical know-how would be a real asset.
