I live about 1/4 mile from the Interstate Highway. I am far enough away the traffic can not be heard until the sun is very low on the horizon. Every even for about 1 hour when the sun is very low it sounds like the interstate traffic is in my back yard. It is so loud it is just like standing next to the highway. Once the sun goes on down traffic can not be heard. Also I built a very good TV antenna. I receive 46 crystal clear station from 40 miles away. The antenna is over kill on purpose no matter how bad the weather gets, rains, snows, fog, hail, tornado, wind, trees, nothing blocks the signal we get crystal clean TV reception. But every day for about 1 hour when the sun is very low on the horizon TV reception for several station is zero and other stations break up too bad to watch. What does the sun have to do with these 2 strange phenomena?
