I'm guessing the network admin is allowing that specific one at this point. Assuming it is Ferndale that's affiliating, they're not adjacent to the other DPD districts. I've also noticed that DPD Track 6 is not on the Oakland simulcast 100%.I understand how the system works and the roaming, but the Oakland site denies almost everything not originating in Oakland. I wonder how / why DPD6 is allowed when others are not.
