A phenomenon called called tropospheric ducting is currently affecting Classical IPR's 88.5 FM signal from Mackinaw City.
This phenomenon can affect FM signals by strengthening weak signals, interfering with local transmitters and preventing signal return.
During these periods, Classical IPR's 88.5 FM and/or 88.7 FM signal is sometimes affected by another 88.5 FM or 88.7 FM signal from a Christian station in Appleton, WI. The signal may also be weakened significantly.
IPR's broadcast engineer is aware of the interference and monitoring the situation.
We apologize for the inconvenience and thank you for your patience.
