Does such a receiver used as a computer clock really win over using the 60Hz line frequency ? Although for any short period of time, if the receiver picks up WWV, its time keeping should be more accurate than using the 60Hz, it is my understanding that the power companies strive to make the long-range accuracy of the 60Hz signal very good. Whereas with the WWV receiver, there would be no mechanism to insure that time losses would be balanced by time gains. My current experience is that digital clocks operating off the 60Hz are more accurate on a month by month or year by year basis than most crystal-controlled watches. Cheers, Dan Ts'o ...cmcl2!rna!dan
