TWiRT 720 - 720 kHz with Pierre Lonewolf and Bill Murdoch

TWiRT - This Week in Radio Tech - Podcast

Amazing that this worked out, but thanks to Pierre Lonewolf’s topic idea and Bill Murdoch’s eagerness to join us, we have a fun and informative TWiRT episode! Two chiefs who engineer at two different high-power AM radio stations - each broadcasting at 720 kHz on the AM dial. And we’re having this conversation on episode 720 of “This Week in Radio Tech!” It had to be fate! Between Pierre and Bill, we find plenty of similarities and some big differences in their transmitter operations. Pierre’s station is KOTZ in Kotzebue, Alaska. Bill’s station is WGN in Chicago, Illinois. The towers are about 3,200 miles apart from each other, so neither station gets interference from the other, but each station has interesting and individual challenges. You’ve got to check out Pierre’s and Bill’s Tips of the Week at the end of the show. Great wisdom there!
