The Military back in the 60's and70's used tropospheric scatter to set up long range communications. Satellites took over not long after in the late 90's.Troposphere ducting. Broadcast FM is VHF, and it can happen occasionally. Us ham radio operators love it.
Really high power though. The capacitator banks used caps as big as 55 gallon drums and had to be discharged before working on them. Quite the experience on the discharge crew.
