Hi all: This past Sunday I noticed I was getting 4 time signal stations on my radio: 15, 10, 5, 3.33 MHz. When I timed the time signals I found about a 1 sec spread, unusually large I thought. Anyway, no 2 signals were exactly the same. Does this have some affect on the non-GPS timing for observers that rely on radio time signals? In the evening, I usually can only hear the station at 3.333 MHz. PeterG. Yes.. Has to do with the distance the signal has to travel from the broadcast station to you.. Here is a link to a great circle calculator.. http://williams.best.vwh.net/gccalc.htm A correction to the time has to be made to account for this. It is a small change, but for accuracy...
