Global Simulated Emergency Test

Saturday November 8th 2008 04.00 - 08.00 UTCIARU Region 1 invites the HQ-Stations of all IARU member societies andstations of Emergency Communications Groups to participate in a GlobalSimulated Emergency Test on Saturday November 8th, 2008 04.00 – 08.00UTC. The operation will take place on and near the emergencyCentre-of-Activity (CoA) frequencies on 80, 40, 20, 17 and 15 metres (+-QRM ).The objectives of the test are;1/ increase the common interest in emergency communications.2/ test how usable the CoA frequencies are across ITU regions.3/ create practices for international emergency communication and4/ practice the relaying of messages using all modes.Please remember that this is not a contest, it is an emergencycommunications exercise !Following the recommendation of the GAREC conferences, participatingstations are requested to use /D in their callsign (D=distress/disaster)where permitted by their licensing administration.Traffic may be passed on voice (SSB), Data or CW modes as detailed below.Voice modeEach IARU Region will have a HQ station operating on voice as follows:Region 1 – GB4NRCRegion 2 – XE1LMRegion 3 – BY7PP

W1AW to Participate in Global Simulated Emergency Test (Nov 4, 2008) -- On November 8, W1AW, the Hiram Percy Maxim Memorial Station, will be participating in the 2008 Global Simulated Emergency Test (GlobalSET), sponsored by IARU Region 1. The event runs from 0400-0800 UTC, but due to the W1AW transmission schedule, the ARRL station will be on the air from 0500-0800 UTC. ARRL Emergency Preparedness and Response Manager Dennis Dura, K2DCD, and ARRL Regulatory Information Manager Dan Henderson, N1ND, will be on the air from W1AW. According to event organizer Greg Mossop, G0DUB, the GlobalSET is an exercise for headquarters stations of IARU Member Societies and stations of emergency communications groups -- it is not a contest. Activity will be concentrated around the IARU Emergency Centre of Activity frequencies. Where permitted by their licensing administration, participating stations will use “/D” after their call sign, indicating distress or disaster. A list of participating stations can be found here.

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.
