Great info
Thanks!


: Yes - numerous times.

: It's possible WCSJ-FM was off the air for a while because of the storm. Distant stations are normally heard in the background, though weakly audible if a local station is off the air. Often when a cold front passes through a region, as happens when thunderstorms approach is that there can be some tropospheric enhancement of signals in the area, thus enabling reception of the more distant signals.

: When the tropospheric enhancement is particularly strong, there is a possibility that a more distant signal may override a local station that is on the air, depending on the orientation of the receiving antenna, the sensitivity of the receiver, and the signal strength of the local station as received by the receiver.

: On FM, what is known as capture effect may allow another distant station only a few decibels stronger in signal strength than a locally received signal to be heard.
