IARU Region 1 SSB/CW Emergency Test – Saturday 10th December 2022

IARU Region 1 invites stations of Emergency Communications Groups in region 1 to participate in a Global Simulated Emergency Test on

Saturday 10th December, 2022 14.00 – 16.00 UTC

The operation will take place on and near the emergency Centre-of-Activity (CoA) frequencies on 40 and 17 metres (+-QRM ).

This is a short notice event to test how well emergency communications groups can set up networks from home or temporary locations. Messages will be passed in both directions so please keep notes of who you can work as you may be asked to relay outgoing messages to their destination.

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 and
4. practice the relaying of messages using all modes.

So, please remember that this is not a contest, it is an emergency communications exercise to develop the skills we will need to provide an international emergency network.

Messages may be passed on voice (SSB) or CW modes as detailed below.

G0DUB will be active to receive messages on the frequencies ( +-QRM ) as shown below.

7110
18160

Stations intending to participate are requested to register through their IARU R1 National Emergency Communications Co-Ordinators.

Participating Stations

CT1REP
CS5MFR
G0DUB
OM1HI
OM6BPA
OM8AGA
OM8ST
PA2EJD
PD7AVR

Participating stations should call ‘CQ GLOBALSET’.

Message Format

Each participating station will send messages to the Control station formatted using the IARU HF International Emergency Operating Procedure which can be seen here. That page also has the message forms to be used for the exercise.

Stations should relay messages received towards the Control station for that band or mode.

To comply with licence regulations, all messages should be addressed to a licensed radio amateur taking part in the exercise.

Messages should be less than 25 words and *must not* include anything which would be considered as a ‘real emergency’ message by a listener.

For example;

* Weather report at the station location
* Number of operators available
* Availability of emergency power
would all be acceptable messages.

There is no limit on the number of messages to be sent but each one must have a unique message number.
To avoid QRMing the control stations, please move to frequencies near the CoA in steps of 5KHz for contacts with others.

To create a more realistic situation, please limit your transmitting power during the exercise to 100 Watts. We are especially interested in stations operating mobile/portable and/or on emergency power.

CW Mode

CW is included in this SET to increase the possibility of stations making contacts in difficult conditions. CW stations should operate near the CoA frequencies where SSB traffic cannot be heard.

CW stations must send the same format as used for voice messages and not exceed 15wpm.

Conclusion

A log sheet for messages passed is provided here so that analysis of the exercise will be easier. Stations are asked to submit logs of the messages relayed, not the messages themselves.
