Having worked for TM's programming division, I don't recall KDNT as a customer, I could be wrong though.
When religious KDTX evolved into super soft rock KMGC in late 1977, they used what was marketed as the TM "Beautiful Rock" Format
as the soft rock, singer-songwriter format had a bit of traction back then. It was an interesting music mix, initially consulted by the same guy (George Burns) that programmed TM Stereo Rock. Trivia, the back announce announcer for TM Stereo rock was the great John Borders. TM Beautiful Rock was back announced by Jack Schell. And the country format? Sam Bogart.
When KMGC ran the format they had all live jocks including the late Jerry Houston and the late Steve Nichol.
TM Beautiful Rock evolved into an AC format and then eventually died when Satellite Music Network and Transtar (remember Format 41?) arrived in the early 80's.
TM Stereo Rock was a very successful format back in the day.
