The Doctor Is IN: Antennas for Domestic Contests
By / 2009-11-08 08:17:49Just the other day, the Doctor and I got to talking about ARRL Sweepstakes. I showed him my crystal mug and whisk broom from last year's Sweepstakes running (the W1AW team did quite well), and he showed me what kind of antennas I should look into for domestic contests. Being more of a DX RTTY contester, I really don't know…Read More + -

ARRL Launches New DIY Campaign

The ARRL Public Relations Department has released the Do-It-Yourself (DIY) suite of interrelated promotional materials aimed at exposing the growing Do It Yourself/Maker community to Amateur Radio opportunities. The DIY movement is nothing new to Amateur Radio. For more than a century, hams have been working in basements and attics, taking things apart and putting them back together in new ways, just for the fun of it. Meanwhile, there has been a growing population of DIY hobbyists who do not know about the opportunities of Amateur Radio. “Maker Faires” have popped up in several areas of the country, from New York to Los Angeles, and according to ARRL Media and Public Relations Manager Allen Pitts, W1AGP, look suspiciously like ham radio conventions.
“The DIY crowd is as diverse as hams,” Pitts explained. “Many are into computer programming, using new computer chips and open-source electronics prototyping platforms, such as Arduino that are based on flexible, easy-to-use hardware and software. They are artists, designers, hobbyists and anyone interested in creating interactive objects and applications. DIYers work with everything from wood and clothing, to energy and chemistry projects, with many interested in robotics.”

Expedition 29 Commander Mike Fossum, KF5AQG, and flight engineers Satoshi Furukawa, KE5DAW (JAXA) and Sergei Volkov, RU3DIS (RKA), will welcome their new crewmates when the hatches open a couple of hours later, at about 0655 UTC. Burbank, Shkaplerov and Ivanishin are scheduled to live and work aboard the ISS until March.

ARISSat-1 -- the latest Amateur Radio satellite -- began its education-based mission after deployment from the International Space Station in August 2011. The ARISSat-1 mission is to provide a variety of information through its many broadcast modes promoting STEM-based education initiatives in the classroom. In an effort to help realize this mission, the ARRISSat-1 Team is sponsoring a CW contest.
To participate, listeners need to copy and submit any six of the more than 200 call signs transmitted during ARISSat-1’s multiple satellite passes. Once you have at least six call signs, submit them via This email address is being protected from spambots. You need JavaScript enabled to view it. ">e-mail to receive a special certificate. Along with your six call signs, please include your name, your call sign (if you have one), the time (in UTC) and date of reception of each call sign and your city, state and ZIP Code.

The average daily sunspot numbers this week were about the same as last week, while the average daily solar flux declined a little more than eight points to 128.9. Geomagnetic indicators were quiet. The average daily sunspot numbers of 95.3 for the week is considerably below the average for the previous 90 days, which was 120.8. Sunspot numbers for December 15-21 were 44, 60, 95, 103, 133, 139 and 93, with a mean of 95.3. The 10.7 cm flux was 124.2, 121, 119.6, 127.4, 128.2, 137.4 and 144.5, with a mean of 128.9. The estimated planetary A indices were 0, 0, 0, 1, 4, 3 and 3, with a mean of 1.6. The estimated mid-latitude A indices were 2, 2, 2, 3, 6, 5 and 5, with a mean of 3.6.
The solar flux has been climbing over the past week, after a low of 119.6 on December 17. The predicted flux values for the near term are 145 on December 23, 140 on December 24-27, 145 on December 28-30, then dropping suddenly to 120 on December 31-January 2, 125 on January 3-4, 128 on January 5-8, and then peaking at 130 on January 9-17. The predicted planetary A index is 5 on December 23 through January 4, 8 on January 5-6, and 5 on January 7-21. This is from NOAA and the U.S. Air Force Space Weather Operations. There is another opinion, of course: Geophysical Institute Prague predicts quiet conditions December 23, quiet to unsettled December 24, active conditions December 25, unsettled to active December 26, quiet to unsettled December 27 and quiet again on December 28-29.
Active conditions are quite different from an A index of 5, although the NOAA/USAF outlook is at least eight hours newer than the Prague prediction. But looking back 24 hours earlier to the December 21 prediction, USAF/NOAA has nothing different on December 25, although they do show an A index of 8 on December 29. You can check here for the latest prediction, which is updated daily after 2100.
