I just finished reading a book, CRYSTAL CLEAR, by Richard J. Thompson Jr. The book presents the fascinating history of the World-War-II effort to provide crystal frequency control for military radios. This was critically important, because radios without crystal control drifted badly, which made net operation difficult and also made it impossible to assign closely-spaced radio channels.
The book was announced in the New Book section of the June 2006 QST. The book's author had written a nice summary article on the same topic that appeared in the January 2004 QST. I make mention of the book here because I know that many members of the Elecraft list have long memories and share my fascination with radio's technical history. (Like Ron, AC7AC, I too remember Edward R. Murrow's reports from London during the Blitz.) I do not know Professor Thompson, and I have no vested interest in the sale of his book. 73, John, no8v _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
