One might presume so, incorrectly. It was common convention to use kilocycles (KC) and megacycles (MC), excluding any reference to "per second." Here's an ARC-5 transmitter, showing same: http://hug-a-bug.com/arc5b.jpg This convention also carried over into more formal texts: http://www.nj7p.org/manuals/arc-5/arc-5.html#_Toc460591310 Hertz himself, although occasionally making reference to "times per second", more often used "period of oscillation" and usually used wavelength, which makes sense, since this was much easier to measure at the time. Here's a brief portion of "Electrical Waves": http://historical.library.cornell.edu/gifcache/cdl/cdl334/00134.TIF6.gif _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
