Re: GPS reference frequency standard?



Allen,
Several of us in the San Diego Microwave group have assembled the N1JEZ 
board and Jupter GPS. Results here are great, it compares favorablly with 
the H/P 3801 except it will come up and lock in less that 20 minutes. The 
Jupter  GPS has a 10 KHz output instead of the 1 PPS output. This system is 
portable and gets down to a few parts in 10 to the -10 in less than a 1/2 
hour. Assembly is not difficult if you are famillar with Surface moun 
techniques.

Art,
KC6UQH
