Radio Amateur Society of Thailand Needs Our Help

Ham radio groups from around the world are being asked to assist the Radio Amateur Society of Thailand which is seeking help to rebuild its headquarters station, HS0AC. This following massive flooding that recently hit that nation not long ago.
--
According to Dick Flanagan, K7VC, in Minden, Nevada, there have already several offers of equipment to the Radio Amateur Society of Thailand from members of the Northern California Contest Club. Also Rusty Epps, W6OAT, reports that the Yasme Foundation sent the Radio Amateur Society of Thailand a $2,000 donation to assist in the HS0AC rebuilding effort. But that will be only the beginning of what’s required to bring the station back on the air.

Flanagan says that what is probably needed most right now is someone or some organization to coordinate the assistance effort, solicit the offers and manage the shipping and paperwork. He speculates that perhaps that administrative role could be taken on as a cooperative effort between the Northern California Contest Club, the Northern California DX Club, the International DX Association and perhaps the ARRL.

K7VC notes that this would be a wonderful way for individuals and clubs to express their holiday feelings of generosity to our fellow hams in need, He adds that we can use this opportunity to demonstrate to our Thai ham radio brothers and sisters what a coordinated effort can do to help them rebuild their wonderful station. Those with suggestions can contact Dick Flanagan by e-mail to dick (at) k7vc (dot) com.

Rescue Radio: Changing Times - ARMY MARS PHASING OUT WINLINK

The Department of the Army has announced that it has begun to take steps to phase out the use of the WINLINK System. This is because of possible security breaches that might be incurred in the Internet aspect of transmissions using the mode. Amateur Radio Newsline's Bruce Tennant, K6PZW, has more:
--
According to the December 21st ARRL ARES E-Letter, the military chain of command that governs Army MARS feels that the Internet portion of WINLKINK leaves the system significantly open to the possibility of intrusion. To deal with this it plans to replace WINLINK with a newer military e-mail system that has extensive protection against any form of hacking or any other form of incursion.

To accomplish this, Army MARS will be expanding on the concept of a national network that is voice, RTTY and PACTOR capable under MIL-STD 110A. It says that PACTOR will become even more important as the new areas of focus will be peer to peer and keyboard to keyboard PACTOR based communications.

Amateur modes such as MT-63, OLIVIA, and WINMOR, which cannot be used by the military, will be eventually phased out as well.

The ultimate goal of this change will be to help Army MARS return to what it is really supposed to be. That of a radio-only system to relay long haul traffic as it has done very successfully in the past.
--
While these changes will affect Army MARS nationally, it is not abandoning state and local served agencies. Army MARS says that it is moving away from providing them a winlink.org e-mail address. (ARRL ARES E-Letter)

CME expected at Earth on 28 December 2011

New sunspot 1387 erupted during the late hours of Christmas Day, producing an M4-class flare and hurling a CME toward Earth and Mars. Click to view an animated forecast track prepared by analysts at the Goddard Space Weather Lab:



The CME is expected to deliver a glancing blow to Earth's magnetic field on Dec. 28th at 1200 UT and a direct hit to the planet Mars on Dec. 30th at 1800 UT. Using onboard radiation sensors, NASA's Curiosity rover might be able to sense the CME when it passes the rover's spacecraft en route to Mars. Here on Earth, NOAA forecasters estimate a 30-to-40% chance of geomagnetic storms on Dec. 28th when the CME and an incoming solar wind stream (unrelated to the CME) could arrive in quick succession.

“The DIY Magic of Amateur Radio”

ARRL VIDEO TO BE RELEASED VIA DECEMBER 27th AND JAN 3rd NETCASTS
Two dates to mark down on your ham radio social calendar. The first is this Tuesday, December 27th at 8:30 p.m. Eastern time. That’s when the ARRL will present an on-line premiere screening of its new video titled The DIY Magic of Amateur Radio.

To accomplish this the League has teamed up with Tom Medlin, W5KUB, who will be streaming it from his website at w5kub.com. The video will also be released earlier that day on-line at the ARRL’s own website at www.arrl.org and on the ARRL video pages on YouTube dot com. All three are a part of a new ARRL public relations campaign to interest the nations maker and hacker community in our world of ham radio.

Then a week later on January 3rd at 9 p.m. Eastern, the shows producer Bill Pasternak, WA6ITF, along with Director Dave Bell, W6AQ and writer Henry Feinberg, K2SSQ, will be the guests of Bob Heil, K9EID, and Gordon West, WB6NOA. This on their weekly TWIT dot TV video podcast known as Ham Nation.

Bell, Feinberg and Pasternak will give you a behind the scenes look at how the DIY Magic of Amateur Radio video was conceived as well as how it was put together using the very latest digital video production techniques. You will also get to see the video in its entirety.

Look for this live netcast at 9 PM Eastern on Tuesday, January 3rd at live.twit.tv. If you miss it, wait about 24 hours for it to be posted at twit.tv/hn. (ARRL, ARNewsline™)

Amateur Radio Operators to host Kids Day

Kids Day is an on-air event to encourage young people (licensed or not) to have fun with Amateur Radio and takes place Sunday January 8.

The Kids Day operating event is not a contest. It’s a way to tell young people worldwide about the magic and mystery of two way hobby radio communications.

To do this, Amateur radio stations are being asked to devote this short time window to promote the terrestrial hobby and ham radio satellite operations to youngsters. This, by providing a place to make contacts with other Kids Day stations around the world.

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
