[ntp:questions] Two time sources with offset => fails to synchronize

[Thierry MARTIN]

Hi all,

I am running ntp 4.2.0 on FC5.
Two time sources:
	- embedded GPS board(Meinberg board)
	- remote Radio clock synchronized ntp server (stratum 1)

It seems that the Radio clock has 50ms offset compared to the GPS 
source, which leads a failure in synchronisation.

I am looking for some documentation that explain why it fails.
Which parameter(s) in the configuration triggers that behaviour?

I used the "prefer" keyword in the GPS configuration line, with the same 
result. Is there a way to make it work better?

Thanks for you help
