In searching for an article on QRSS, I encountered a phrase that may or may not comprise the words for which the QRSS scheme the article describes constitute an acronym: quasi-random signal source. As far as I can tell, the article does not say that the QRSS technique it describes stands for quasi-random signal source. (I searched the article for the text strings "quasi-randon" and "quasi random" and came up with no matches.) However the modulation scheme described in the article (which I'm pretty sure IS the QRSS we are interested in) is related to picking signals out of random noise by using a very slow data rate and very narrow-band filtering. So this appears to be a case of somebody making a VERY unfortunate choice of acronym! (And BTW, if I've figured it out correctly, the QRSS of interest to this group is not, strictly speaking, an acronym--because the letters QRSS are not the first letters in the words of a phrase that is the "longhand" name of the technique.) Apparently the QRSS of interest to this group is ham-speak for "slow your transmission speed (word rate) WAY down." -- Dan Strassberg, [EMAIL PROTECTED] eFax 707-215-6367 _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
