I have experienced this myself with just a cheap FM radio. Aircraft
frequency 118.5, radio station 96.9. Aircraft communications were not
very clear, but it was obvious what it was when planes were very close.

At OSH, I found that you could pick up Chicago center on the low range of an
FM radio, if you had the antenna just right, held your tounge in the correct
corner of you mouth, ect, ect. It was coming from a transmitter antenna on
the grounds, I suspect, and all that could be heard was the center side of
the transmission.
