Yea for the most part the sectors designed for each airport is at that respective airport. I was looking through the Standard Operating Procedures (which most SOPs do list transmitter sites) and I cant find a list of the RCOs for satellite sectors which will be the only transmitters not based at IAH or HOU. I'll keep looking and If I find some I'll post in here. I sure would love to have a I90 Tracon feed back up as I have a real good friend at I90 that I would like to hear.
