ARLX005 Global Simulated Emergency Test Scheduled for April

The HQ Stations of all IARU Member-Societies, as well as the
stations of Emergency Communications Groups, have been invited by
IARU Region 1 to participate in the 2009 Global Simulated Emergency
Test (GlobalSET), on Saturday, April 18, 2009 from 1100-1500 UTC.
The GlobalSET will take place on and near the emergency Center of
Activity (CoA) frequencies on 80, 40, 20, 17 and 15 meters, +/- QRM.
Stations in the United States intending to participate need to
register through their IARU International Emergency Communications
Coordinator. For the United States, registrations should be e-mailed
to ARRL Emergency Preparedness and Response Manager Dennis Dura,
K2DCD at,

Dura confirmed that W1AW will participate in the GlobalSET.

According to IARU Region 1 Emergency Communications Coordinator Greg
Mossop, G0DUB, the GlobalSET is not a contest, but an emergency
communications exercise to develop skills needed to provide an
international emergency network.

Mossop said that the GlobalSET has four objectives:

 To increase the common interest in emergency communications.

 To test how usable the CoA frequencies are across ITU regions.

 To create practices for international emergency communications.

 To practice the relaying of messages using all modes: Voice (SSB),
 Data or CW.

"The exercise will build on earlier GlobalSET exercises and will
focus on generating and relaying messages in a common format across
country borders, rather than the information gathering capabilities
that we've done in the past," Mossop said. "We will pass messages in
a format that we may have to use for the agencies we may serve. The
message exchange will take longer than in previous exercises, and
stations will have to be patient to transmit their messages across
country and language boundaries."

Each participating station is to send messages to their Regional HQ
station using the IARU International Emergency Operating Procedure,
using IARU message forms. Stations should relay the messages they
receive to their Regional HQ station; the Region 2 station is TG0AA
in Guatemala. To comply with license regulations, all messages
should be addressed to Greg Mossop, G0DUB, and should come from a
licensed radio amateur. Messages should contain fewer than 25 words
and should not include anything that would be considered as a "real
emergency" message by a listener. Mossop suggests constructing
messages that include weather conditions, the number of operators at
the station or even an interesting fact about the station. "There is
no limit on the number of messages to be sent," he said, "but each
one must have a unique message number." Regional HQ stations will
not be sending messages, only receiving them.

Mossop recommends that in order to create "a more realistic
situation, please limit your transmitting power during the exercise
to 100 W. We are especially interested in stations operating
mobile/portable and/or on emergency power."

Usually held in May, the 2009 GlobalSET was moved to April to tie
into World Amateur Radio Day. The theme of the 2009 World Amateur
Radio Day is Amateur Radio: Your Resource in Disaster and Emergency
Communication. "This is an ideal opportunity to showcase the work of
emergency communications groups around the world," Mossop said.
