Thanks Paul. I remember when I joined this group a few weeks(?) ago I was just looking for some cheap way to improve the accuracy of my counter. So I decided to build a cheap, entry level GSPDO. And I bought a 3456A because I didn't understand my code had a positive feedback loop.. And I got a 5335A. And I spent many many hours turning Bert's FLL into a PLL. And now I'm getting a Rb standard as a check for the code I'm "perfecting" for my GPSDO. You guys were right. This time stuff is more addictive than crack. I just tell everyone I'm building a time machine. =)
