Ken, thanks for the help. From the lat/lon data available in the database, I see that the transmitter for the State System's Norman site is apparently on the same tower as one of Norman TRS' transmitters. This is conjecture on my part, but it stands to reason that there could a patch device on site, or at Norman's dispatch that links the two systems togther. Like you, I'm sure others more familiar with the systems can shed some light.
