Things change. When ch 9 KWTV tower went up in Edmond in 1953, KWTV stood for World's Tallest Video. No more. The 1953 tower came down and was sold for scrap.
I've listened to the giant 1520 AM KOMA radio at Pearl Harbor. The 2015 Moore tornado blew down all 3 250,000 watt Western Electric KOKC 1520, former KOMA transmitters. US AM radio stations can broadcast maximum 50,000 watts.
Rumor has it KOMA engineers would up KOMA power to 250,000 watts in the wee early morning hours so the doggies in Vietnam could listen in. My old USAF buddy told me he listened to KOMA every night in the Aleution Islands.
