At 6 p.m. on November 8, 1959, KRBE signed on at 104.1 FM as a classical music station by owners Roland and Edith Baker. There was much naysaying about the full potential of FM radio technology and its future success. It was a risky venture. The early FM radio receivers drifted in frequency making the audio sound "fuzzy". This required intermittent adjustments to the analog tuning dial. Later, the "phase lock loop" circuit was invented which cured this problem. The static-free FM signal then was launched to its full commercial potential.
