The digital transmitter could have a GPS based frequency reference.
I am the CE for a local station (WCIV).
We do not use any standard other than what is installed in the transmitter.
I have not verified it, but, I think that the UHF transmitter
frequency is controlled by an OCXO.
I will try and remember to check on this Monday.
I do know that our Analog transmitter used an ovenized crystal for
frequency control. We were on channel 4.
We definitely are not slaved to the network for frequency control.
