630m Heating Up

by Steve VE7SL

n spite of the sun’s nasty and continual huffing and puffing, conditions on 630m continue to surprise many of the nightly diehards. It seems clear, that for the time being, the digital WSPR mode is the one chosen by the majority of operators. I suspect that this will change to a more proportionate mix of both CW and digital, as more Canadians get on the band but more particularly, when U.S. amateurs get permanent access to 630m as a ham band. At present, it’s mostly listeners reporting beacons, demonstrating the propagational capabilities to be found at the bottom of the broadcast band.

Hams Support Air Force Marathon

When the 15,000 plus runners sprang from the starting line at the recent 2015 Air Force Marathon and related races, 65 ham radio operators were on duty to make sure the September 19 competition was as safe as possible. Held each year at Wright Patterson Air Force Base near Dayton, Ohio, the Marathon uses base roadways as well as streets in Fairborn and Riverside. Hams are positioned at critical points throughout the courses, not only to provide communication, but to serve as additional eyes and ears, watching for any signs of problems. Hams have been a part of the race since the first official marathon was held in 1997.

ISS astronauts link-up with ITU WRC-15 in Geneva

The ITU World Radiocommunication Conference 2015 (WRC-15) is taking place in Geneva from November 2-27. On Tuesday, November 3 at 1241 UT there was an amateur radio link-up between WRC-15 and two astronauts on the International Space Station (ISS).

The contact took place using the permanent amateur radio station at the ITU. The station’s normal call sign is 4U1ITU but during the conference the special call sign 4U1WRC is being used.

Solar Update

The K7RA Solar Update

10/30/2015Solar flux and sunspot numbers barely budged last week. Average daily sunspot numbers went from 75 in the previous seven days to 77.6 in the week ending October 28. Average daily solar flux went from 118.2 to 110.9.

Predicted solar flux is 110 on October 30, 105 on October 31 and November 1, 100 on November 2, 95 on November 3-4, 90 on November 5, 85 on November 6-8, 90 on November 9, 95 on November 10-11, then 100, 105 and 110 on November 12-14, 115 on November 15-16, then 120, 115 and 110 on November 17-19, and 105 on November 20-24. Flux values then drop to 85 on November 30 through December 5, and next rise above 100 a few days later.

Predicted planetary A index is 12 on October 30-31, 8 on November 1-2, 45 on November 3-4, then 20, 15 and 12 on November 5-7, then 20, 25, 20 and 10 on November 8-11, and 8, 12 and 20 on November 12-14, 5, 8 and 12 on November 15-17, then down to 5 on November 18-21.

Geomagnetic conditions remain unsettled, then on November 30 through December 2 planetary A index is predicted to rise to 50, 40, and 25, an echo of the high values on November 3-5. In fact, this activity would be from the same area of the sun a whole solar rotation later, which takes about 27-28 days.

Here is the geomagnetic outlook from Petr Kolman, OK1MGW, of the Czech Propagation Interest Group. He expects the geomagnetic field to be quiet to unsettled October 30, quiet to active October 31 through November 3, active to disturbed November 4-5, quiet to unsettled November 6, quiet to active November 7-9, quiet to unsettled November 10, quiet to active November 11-13, mostly quiet November 14, quiet November 15-16, mostly quiet November 17-24 and quiet to unsettled November 25.
