Because of Mr. Hillebrand's fascination with new radio technology, WMHE was partially automated. The automation consisted of a bank of six cartridge "carousels" each holding 24 tape cartridges. All of the music was on these cartridges or "carts" (similar to 8-track tapes), but only one item (a song, a voicetrack, or a commercial) was on each cart. The jocks would record their announcements on individual carts, usually introducing a song or back-announcing a few songs that had just played in the carousel. Portions of the morning and evening shows were performed 'live'.
