looking at the trace it has the deflections from wwvb in 1 hour segments and at dawn and dusk the shift appears as it should. after days of charting the average trend is close to a straight line and if turned off for weeks it comes back up with the same drift rate . the standard has been on for over a year and seems to be stable. using it as a reference to a sdr-1000 digital radio and on the 25cycle filter all wwv freqs come up on the peak as it should. i guess that means it is pretty close or close as i want it for my use. no it isnt a straight line continous , was using the average reading with a ruler on the graph. hope that cleans up my mistake. think that puts it in a better than low class........ tom w0kgw
