Great pics of the RCAGs!!! For those of you that don't already know, I spent the better half of last year getting all of the RCAGs geotagged on the database here at Radio Reference. For example, if you go to Kansas City ARTCC in the database, scroll down to the St Charles, MO RCAG, click on the little grey arrow next to it's name and select "View Sub Category Details". Then change the map to "Satellite" and zoom on in, you'll see the St Charles RCAG satellite view. Some of the RCAGs geo cords are a little off, but the vast majority are spot on.... I'd say that only 10% or less are a little off. Just another tool for figuring out where the transmitters are actually at. Also, just so you are aware, the receive site for many RCAGs is not the same as the transmit location. The service radius for each RCAG was based on FAA data where they designate that info for the purposes of "service" of the frequencies and is also used in frequency coordination. In other words, the radius serves as the "service radius" for that particular freq and the FAA will not assign the same freq to another RCAG or RTR in that service area unless it is a SELKEY facility. SELKEY means that the sector frequency exists at more than one RCAG, and the controller for the sector can Select the Key (transmit) site from their operating position in the Center. Kansas City Center Sector 53 (Vichy-Low) is an example of a SELKEY frequency since it can be selected to transmit from either St Louis, Maples or Richland, MO.
