This is indeed interesting stuff. First I've heard of the change. But I do have several automatically syncing clocks in the house and have noticed that he syncing isn't as robust and dependable as it was some years ago. For example, switching from standard to daylight savings time and back takes some of them a few days to accomplish, with some of them switching back and forth from day to day before finally getting it right. Don't think that signal strength is the problem. As someone else noted, it sure would be good to know which manufacturers use the new standard! 73 Craig AC0DS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
