Can't cite an specific example but 'moon-bounce' was first achieved
not too long after 1950. Also, meteor trails can reflect all VHF-plus signals including TV and FM. Any time you get a momentary reception of a strange signal it is probably a bounce from such a trail or from a high altitude airplane. We can get Colorado Springs TV stations from airplane bounce here 65 miles north of Denver. Walt BJ |

Walt BJ Walt, Part of that is the location of station antennas on Cheyenne Mountain, 9500'+ but of course most of it is propagation which is why it is art, not science. I was in my apartment in Spokane Washington once and while switching TV channels noticed a picture on an unused channel. No sound but I started watching and the Station break revealed I had just watched about 20 minutes from Waco Texas. The best I have done on the VHF hamband is getting an answer from a farmer in his tractor cab in Sidney Nebraska on a local repeater frequency. I was bringing up both the local repeater and the one in Sidney. Regards, Tex Houston |
