Is that a typo: 100-200 us? Check out: http://www.realhamradio.com/GPS_websites_list.htm
10 us to 1 us or even sub-us is ok. But if it's really over 100 us something for sure is not working right. Send me a some plots and we can work it out. Antenna type; feed cable, obstructed sky view, signal level, number of sats in view, surveyed position, etc. /tvb ----- Original Message ----- From: "Magnus Danielson" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Monday, August 01, 2005 14:48 Subject: [time-nuts] Z3801A predicted holdover phase drift convergence > Hi! > > I have been monitoring my Z3801A and noticed that the predicted hold over > time/phase drift (i.e. frequency error) is fluctuating in the 100-200 us per > day range.
