As of 2018, Emerald Hills is still the home of the KOGO transmitter and its two-tower directional array. The KOGO towers are twin 410-foot self-supported Ideco towers. The original 1948 RCA BTA-5F 5 kilowatt transmitter is still in place but no longer used; it is being acquired by a private collector. The BTA-5F was designed by John Vassos, the father of American art deco design; the 5F was named "The Train" by Vassos, as it looked like a train speeding by. Most of the others have either been destroyed, partially scrapped, or put into private collections. The 1170 KCBQ BTA-5F was scrapped and most of the parts given to KOGO; the pieces of KCBQ's transmitter are still at KOGO for the BTA-5F. There are three remaining complete RCA BTA-5F's: KRKD/KIIS (Brad Hollander collection), WFIL (Mike Dorrough collection), and WIBW Topeka.
