This just came up on a message board, so I though I would post a few frames from what apparently is considered one of the best tropospheric propagation episodes on record. I was in high school at the time in rural Iowa, and in addition to a log-periodic VHF antenna that we needed to get network stations out of Des Moines, I talked my Mom into buying me a UHF yagi antenna. This was nominally to get 17-KDSM out of Des Moines, but I also used it for DXing. Anyway, over the Thanksgiving holiday in 1986 atmospheric conditions were such that persistent long-range reception of TV signals (and other frequencies) occurred in the central and eastern US. I picked up a lot of UHF stations from Indiana and Ohio; UHF was more common in those areas than in most of the country. Here are a few samples; remember that these are single frames, so the actual perceived quality of the video was better; maybe someday I’ll do some frame averaging and put up more pictures, or post some videos to YouTube. Distances are approximate, I haven’t tried to re-calculate them from my road atlas measurements back in 1986.
(PS – These are frames from a VHS-to-DVD conversion I did back in 2004 when I threw out most of my VHS collection.)
