A construction permit (CP) was granted in 2000 by the Federal Communications Commission (FCC) with the call sign KCHY, broadcasting 200 watts covering Hope, North Dakota.

It became popular, and gained larger Arbitron ratings than rival heritage active rock station KQWB-FM "Q98" at times.

Despite a rimshot signal, "The Dam" also attracted more than 2% of radio listeners in the Grand Forks, North Dakota market, somewhat cannibalizing by competing with co-owned sister active rock station KJKJ "KJ108".

KDAM began stunting as "Quick 104.7" again, and later flipped to a country music format as "104.7 The Wolf" in December 2005, competing with KVOX-FM "Froggy 99.9".
