A 3-watt red Luxeon LED at a distance of 14.82 miles (23.85 km) with downtown Salt Lake City in the foreground, as viewed from the south end of the path and looking toward the northeast. north end of the path and looking toward the southwest with a 300mm equivalent zoom. Photo by Clint, KA7OEI. Click on either image for a full-sized version. I did, so I decided to check it out. And I set up the equipment for the evening's main experiment. The spectra of the Laser.

YouTube video about the (former) K7RJ 10 GHz microwave beacon in grid DN31it. In remote northwestern Utah. This beacon, which had been operating on 10368.250 MHz, was regularly heard in the Salt Lake area (approx. 100 miles, 160 km distant) via reflection from mountains and is weak enough to be a good test of one's receive system. A shorter version of this video may be seen here. A report on what is believed to be the first narrowband 24 GHz QSO in Utah. Showing how everything goes together. One of the c...
