So perhaps the solution to listeners confusing WECK with WHTT is something as basic as consistently using frequencies and dial positions ("AM 12-30; FM 100.1; 100.5 and 102.9") with the WECK call letters and slogans presently in use.
Oh my god, who is going to remember that? It's like asking my mother to remember what kind of car she took an Uber ride in this morning.
