Occasionally we have reports of poor reception, bad sounding audio, and interference from other stations on 106.7 FM. This sometimes happens during spring and summer mornings, it’s usually the result of something called “ducting.”
Atmospheric layering caused by temperature, dew point and pressure can create a “duct” for the propagation of a radio signal. The resulting effect is for the signal to be temporarily received in an area where it is usually not heard. This can cause interference and poor reception to local FM radio stations.
