Today at an Aviation Expo at PVD, I had a chance to talk to a controller from the tower about the airspace configuration. They said that they have 6 actual frequencies they can use depending on different factors, but normally 135.4/128.7/119.45/125.75 are the ones used. Basically, 135.4 is their "final" sector. The departure frequency is 128.7. The physical location of these airspaces changes depending on the runway config, of course. As for the other two, 125.75 covers the area around BID, and I don't remember exactly, but 119.45 covers one of the area to the west. (I'm not sure if it's over Groton/Westerly or to the NW) Pretty vauge, but someday I'll try to get more exact details. For whatever reason, I can't find this information anywhere on the 'net, while it's there for most other airports. The most I've found is on a few approach plates, and they don't tell you much anyway. I don't believe that I can recieve 125.75/119.45 due to the transmitter location as stated in the other thread. If you have any other questions, let me know and I'll try my best to get in contact with someone who knows.
