can anyone tell me what does the K mean in a lot of american tv and radio station names?

Dont know what it means but if a station is located West of the Mississippi River it starts with a K, East of the Mississippi starts with a W.

As others have reported and that i'll complex on the callsign element... The FCC desperate interior the Thirties to apply ok west of the Mississippi River and W for callsigns east of the Mississippi to circumvent duplication and make it less difficult to identity probably the place a station is coming from. besides the fact that, some stations have been granted callsigns in the previous this rule, considering those stations that have been grandfathered in by no ability replaced calls, we've stations alongside with KDKA in Philly and WFAA in Dallas who ruin the regulations. yet another element is that some stations have 3 letters rather of four like WBZ in Boston, WWL In New Orleans, and WSM in Nashville. those stations have been granted callsigns in the previous the FCC desperate that 4 letters would be mandatory to grant all stations the thank you to identity. considering those stations by no ability replaced calls in seventy 5 years, we've those 3 letter calls nonetheless out in some areas. Technically the U. S. is allowed Any combos beginning with ok,N,W and from AA-AL ..besides the fact that the A calls are no longer many times used and basically heard with beginner radio operators and the N calls are specially used via the U. S. government as properly as Ham radio and that i think some maritime ships. besides the fact that some posters have been incorrect.... Canada is in basic terms allowed to apply here 2 letters interior the beginning up of any callsign: CF-CK, CY-CZ, VA-VG, VE, VO, VX-VY, and XJ-XO.

The station is west of the mrs.sippy with the exception of KDKA Pittsburgh

no but thats a good question
