what does all this mean. is there a new station coming 2 atlanta?
En ingles, there's a couple of stations that have an FCC permit to start up or move to Atlanta.
One of them is located near Lithia Springs on 890 and is replacing a station at 1000 kHz in the SC upstate. It will only be broadcasting during the day, and will have to cut its power back two hours the first two hours after sunrise and the last two hours before sunset. 5000W is about the same as WDWD (Radio Disney) on 590, for reference.
The other one, on 830, is in Sandy Springs. It can broadcast at a full FCC max 50kW during the day (same as WGST, WCNN, or WSB, although it appears to be directional SW to NE), and, depending on which license they go with, will either broadcast at night 2400W mostly towards the city of Atlanta or 450W in a direction TBD, but probably southward to prevent interfering with WCCO out of Minneapolis, which has a "clear channel" on that frequency.
For reference, at night WCNN is a directional 10kW (mostly excluding the NE), WGST is a slightly N-S directional 1000W, WDWD is 4500W with a NW to SE "snow angel" pattern (which they also use during the day), WQXI is 1000W in a trilobal (N, SW, SE) pattern, and WGKA is a nondirectional 490W. Many smaller stations can broadcast 24/7 at 1000W in any direction.
I have no idea what will be on any of these stations. Sports formats don't work well with daytimers or stations with minimal (<1000W) night power because of night games, but second-string talk is a possibility. Most other smaller Atlanta AM stations are religious or ethnic formats, although I wouldn't call the Sandy Springs station "small".
