While AH6TD is fundamentally an Apple Macintosh station, I have been interested in an absolutely incredible piece of software, free software, called Ham Radio Deluxe. For the longest time, however, I have been unable to use the latest version, version 5, because it was astoundingly unstable. No more. Ham Radio Deluxe 5 is alive and well at AH6TD. . . .

Sunspot activity increased recently, although it is foolish to call this a trend, since solar activity has great variability. Sunspot group 1087 was visible for 13 days over July 9-21. In millionths of a solar hemisphere, its size was 30, 100, 120, 130, 70, 100, 60, 50, 20, 10, 10, 10 and 10. On July 19, new sunspot group 1089 appeared over the eastern horizon, with a relative size of 130, 150, 310 and 240 for July 19-22. Sunspot numbers for July 15-21 were 15, 17, 13, 12, 25, 32 and 38, with a mean of 21.7. The 10.7 cm flux was 75.9, 76.6, 78.7, 76.9, 79.8, 87 and . . .
