Hi everybody, I'm Dennis Tillman I've had a fascination with time for 40+ years but until recently I couldn't afford to do much about that. The highlights:
* Back in 1970 I designed and built my own digital clock out of TTL gates and incandescent(!) seven segment readouts . It ran off a 100KHz Xtal. It still works! * Two years ago I bult my own GPS frequency standard based on the design by James Miller but it has been a big disappointment. I started to suspect it was not reliable so I wrote a LabView program to compare it to the reference outputs of two ArgoSystems AS210 systems I found on eBay and restored. The LabView program confirmed my suspicions that the GPS receiver was briefly loosing its stability for brief periods several times a week. The AS210s tracked each other reliably and extremely closely. I have not gotten to the bottom of the problem with the GPS receiver yet. * About a year ago I got my Spectracomm 8163/8150/8212 WWVB receiver system working. In addition to Precision Time and Frequency measurements my other passion is Tektronix 7000 oscilloscopes. I live in Bellevue, WA nearby to John Miles and Tom Van Baak who have, for better or worse, rekindled my interest in Time.
