More importantly (to me, at least) is Spread Spectrum the most effective or efficient way of using a given amount of bandwidth to deliver a given data rate, from a weak signal point of view? IOW, would ROS work better than, let's say, MT-63, WINMOR, or Olivia if those three modes were adjusted to use the same bandwidth and data rate as ROS? If it were open source, I would have included Pactor-3 in that list, too.
If not, then using SS is counter-productive as well as legally problematic. (I'm not implying that ROS is SS, BTW.) -- Dave Sparks AF6AS -------------------------------------------------- From: "Trevor ." <m5...@yahoo.co.uk> Sent: Wednesday, June 02, 2010 2:29 PM To: <digitalradio@yahoogroups.com> Subject: Re: [digitalradio] What is here Spread Spectrum and why and what is not? > --- On Wed, 2/6/10, KH6TY <kh...@comcast.net> wrote: >> The FCC engineers have performed the same spectral analysis and >> informed the ARRL that the mode is truly spread spectrum. > > That's interesting, the FCC have said they they did not give judgments on > individual data modes, it's up to the operator to decide. > > Who were the FCC engineers you mention, where is their report and who in > ARRL HQ did they communicate with. > > 73 Trevor M5AKA > > > > > > > > ------------------------------------ > > http://www.obriensweb.com/digispotter.html > Chat, Skeds, and "Spots" all in one (resize to suit) > > Facebook= http://www.facebook.com/pages/digitalradio/123270301037522 > > Yahoo!
