[time-nuts] Practical considerations making a lab standard with an LTE lite

[Bob Camp]

Hi

The Linear LT1764 is a pretty good part. It’s nice and rugged / tough to kill. Bypass the output with a few hundred uF of tantalum caps. Keep at least a volt between input and output.

At this moment, I have good lock on 9 GPS birds and a "3d/gps" fix mode reported by U-center.  Interestingly, there are a few GPS birds that show up as blue, even though they have the same C/N ratio as some green birds.  One of them is at 89 degrees elevation -- no blockage like some to the west -- don't get that.
