RDL's ACM technology is the only time-proven, industry accepted method of controlling Synchronous AM Noise (the elusive FM transmission bandwidth variations that aggravate multipath artifacts in listeners' receivers). Hundreds of top performing FMs in every major U.S. market turn to ACM technology for maximum bandwidth performance. Every transmitter, new or old, can easily produce poor bandwidth, or can be made to perform as well as any signal in the market. Every FM station needs ACM technology to provide the accurate AM measurment and continuous monitoring needed for optimum transmitter tuning and performance.
