kit GPS QLG1 #gps

F1BFU - Fr - 79

Hello all
Following the setbacks encountered with my first two QLG1 GPS kits (no pps signal), I have just finished the kit for my third QLG1 and I am having the same problem.
No pps sign on my U3S.
Can you tell me if this problem has already been encountered and what is the source of the problem in order to remedy it.
 have never seen the green LED on once.
4 satellites are tracked.
