the problem was in the syinthesizer board A1 , the xtal oscillator
12.63 was to much aging and was at the limit of pll , now I fixed this
board , now the 12.63 signal is clear and loocked , before was very noisy .
But seeme there are more problem , the signal now is very close to
5MHZ but there are some difference from my rubidium and my Z3805a
The 5 MHZ now is near 5 x 10-10 .
Now I need to ascertain , if there are more fault , or because I have an
high performance tube , I need a degausser ??????
I will continue to study .
all suggestion will be appreciated
