are some of them just reserved and not always used. Does all traffic arriving east use one and all West arrivals use the other?
I'm not the expert for MCO ops, but from what I've heard after checking some of the archives, these seem to be typical configurations used ...
Config 1
124.800 - all arrivals and departures (overnight shift)
Config 2
124.800 - all departures and arrivals
127.750 - arrivals final
Config 3
124.800 - departures and arrivals east
120.150 - departures and arrivals west
127.750 - arrivals final
Config 4
124.800 - departures east
120.150 - departures west
128.375 - arrivals east and west
127.750 - arrivals final
Config 5
124.800 - departures east
120.150 - departures west
128.375 - arrivals east
? - arrivals west (?)
127.750 - arrivals final east
? - arrivals final west (either 125.550 or 134.050 ?)
128.375 is a relatively new frequency and not covered by LiveATC.
The "KMCO Arrival (West)" feed is listed as scanning 125.550 and 134.050, normally this feed is usually simulcasting the final controller on 127.750. I have heard where they split off the arrivals final west onto this radio (Config 5) but I can't tell if they are using 125.550 or 134.050 (if the radio is actually scanning those frequencies) ? There is also the arrivals west in this Config but they don't seem to be using 134.050, at least on the archives I checked, so not sure what frequency is used or if they even split 128.375 ?
Anyone have any more info. ?
