Australia WICIN Responds to New South Wales Brushfires
According to Jim Linton, VK3PC, who is the IARU Chairman Region 3 Disaster Communications Committee, already some 200 homes have been lost as wildfires rage in the Blue Mountains of the Australian state of New South Wales not far from the city of Sydney. News reports attribute one death to the wildfires. A State of Emergency has been declared for the area and fire fighters worry that up to four separate blazes could potentially combine to form a single massive fire front.
Compton Allen, VK2HRX, is the president of WICEN in New South Wales. He says that an official activation has begun, drawing on the resources of the emergency communications group. Currently the mobilization is to support the declared State of Emergency with manpower in the Lithgow area to the west of Sydney.
About 1,200 firefighters were battling blazes across the state. New South Wales Rural Fire Service Commissioner Shane Fitzsimmons said personnel had volunteered to help from all across Australia, and as far away as here in New Zealand. The ground effort is being backed with more than eighty aircraft which were dropping water and fire retardant on the flames.
VK3PC says that evacuations of tens of thousands of people are possible if hotter weather conditions combine with fire fronts already burning. This is a scenario that is literally changing minute by minute and we will have more on it in future newscasts.
WICEN in Australia is comparable to a combined RACES and ARES here in the United States.

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.
