[App_rpt-users] Use of ntpd in ACID

[Jeff Carrier]

Chuck,

I notice an issue with all my URIx's where the TX CTCSS gets out of phase
or something and the radios stop decoding it which makes RX audio kinda
hiccup.  Is this what your speaking of?  I do have the machines pointed at
ntp servers for time syncing.
