Thai Amateurs Respond to Floods, Ask that 7.060-7.063 MHz Be Kept Clear

Authorities in Thailand continue to battle the country’s worst floods in decades, with the death toll rising to almost 300. While Thai hams are mostly using 2 meters to communicate, IARU Region 3 Disaster Communications Committee Chairman Jim Linton VK3PC, is asking all radio amateurs to keep 7.060-7.063MHz clear from unnecessary traffic, as Thai hams are also using 40 meters during the flooding that is affecting millions of people in North and Central Thailand.

“Amateur Radio has been assisting with flood relief communications, helping victims in the affected areas, said Tony Waltham, HS0ZDX, the Radio Amateur Society of Thailand’s (RAST) International Liaison Officer. “Operators are using RAST’s club station call sign HS0AC, and a special flood relief center with the call sign HS0AB has been established at Bangkok’s Don Mueang Airport. Please be formally advised that Thai radio amateurs are standing by on 144.900 MHz, 145.000 MHz and 144.9375 MHz, as well as on frequencies of 7.060-7.063 MHz in the 40 meter HF band.” Waltham noted that RAST has posted a video (in Thai) to YouTube, showing the activities at the special flood relief Amateur Radio station at the airport.

Despite sandbags, Bangkok -- the country’s capital -- is under threat of flooding. In outlying areas, the floods have destroyed crops, inundated factories and damaged the homes or livelihoods of millions of people. About 110,000 people have sought refuge in shelters. It is expected for the flooding to continue for a week. The high tide will prevent the floodwater's escaping to the sea for a day or two, while the recovery efforts may take a year.

According to Linton, nearly three million people are affected by the floods, and the disaster has caused serious damage to the country`s agriculture and other industries, with Japan’s Toyota, Sony and Honda, along with USA’s Western Digital -- and many other factories to the north of Bangkok -- suspending production until the situation improves. Damage so far has been assessed at more than 20 billion baht ($65,295,400 USD). Waltham said that 26 out of the country’s 77 provinces are affected, and Bangkok is bracing for a large amount of run-off water that will coincide with the seasonal high tides, making it harder for the flood waters to flow out to sea

Comet Elenin

Today the world will not end! The supposed “Doomsday” comet Elenin will pass by, but at 35 million km or 90 times the Earth Moon distance, it will have NO effect on us at all.

It is about 3-5km wide and has the consistency of a slushee or snowy dirtball. It is so feeble that a strong solar storm in August appears to broken it into smaller pieces. Rising in the east very early in the morning at magnitude 10 it is not visible to the eye or even moderate sized telescope. An image by Michael Mattiazzo can be seen at:

KD8BIG

Whoa, it has been nearly 4 week’s sine my last post.
It is amazing how fast time can escape you.
The last 4 weeks have not been good to me; I had a battle with Bacterial Pneumonia, the passing of a couple of friends, sick daughter & wife & other issues.

The good news is I/we are feeling better and I am ready to blog, play radio and catch up on some of my collections.

How about those Detroit Tigers~ (MLB) Oh yeah, they have a chance. If not that is fine, they had a great season and I look forward to next year.
I am glad that Football (NFL) & Hockey (NHL) are underway.

The weather has turned here in Michigan; most of the leaves have peaked and dropped in my region. The temps are now 50’s (10º c) for the high and mid to upper 30’s (1.6ºc) for the lows.
My son and wife have already begun the leave removal process. Most of the summer lawn furniture has been stored and I think we are ready for the long and cold winter months that are fast approaching~

I have made some upgrades to the shack, added some new equipment and also hope to upgrade my license very soon. I was to do that a few weeks ago but was very sick.

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.
