 New Wave was granted a construction permit and the call letters K56AU.Two attempts were made to re-broadcast PTV signals, first from KETC, St Louis, with a series of microwave relay towers which was only marginally successful.Later New Wave built a huge custom engineered UHF receiving antenna atop the Paquin High Rise building (affectionately called "The Fence" by the group of volunteer engineers who constructed the thing) to receive a public television station signal from Kansas City, KCPT.
