[App_rpt-users] Use of ntpd in ACID

[kk6ecm]

Using ntpdate at the command line returned this response

 

29 Mar 11:30:35 ntpdate[3376]: no servers can be used, exiting

 

does that mean it did not update?

 

Thanks,

Bob

I have no problem running ntpd in my ACID servers that only have RTCMs
interfacing with radios.  But when I use usb sound interfaces (URI or usb
sound fob) then I find that ntpd causes anomalies in the audio.  Many people
don't notice it but I do and anyone with a good ear will notice it and
comment about the audio sounding strange and blame it on using a computer in
the audio path.  

 

Turn ntpd off and just use ntpdate once per hour and the strange audio
sounds go away.

I have seen this in various systems and while it is worse in slower single
core systems, it is still slightly present even in high end quad core
systems.
But it is not present at all when using only RTCMs.
