This Emergency Communications Exercise is aimed mainly at amateur radio stations in the countries of IARU R2 Area G: Argentina, Chile, Paraguay and Uruguay.


  1. Help radio amateurs in Area G acquire experience in Emergency Communications, measure response capacity and promote work and cooperation among operators.
  2. Count on a database of radio amateurs interested in participating in Emergency Communications.
  3. Encourage the operation of stations operating with their own energy, low power, portable and mobile


  1. Individual radio amateurs, radio clubs and institutions with a valid amateur radio license in Area G countries: Argentina, Chile, Paraguay and Uruguay.
  2. Idem: from other countries willing to join the Exercise.

Date and time of the event

Saturday, August 26, 2017, from 21:00 to 23:00 UTC.

Bands, frequencies and modes

  1. 40-meter band, 7.050 kHz SSB
  2. 20-meter band, 14.255 kHz, SSB
  3. Radio amateurs that because of their category or equipment don’t have access to these bands can participate as listeners. We suggest that they contact a participating radio club or group to follow the exercise jointly with more experienced radio amateurs so that they begin to understand how traffic is managed within a Net.

Mode of the Exercise

  1. During exercise hours, a Control Station will be on the air for each Area G country; they will operate as Net Control in an alternate manner, in order to have coverage in the entire Area.
  2. The Member Stations from each country in the Area will be available to act as Control Station or must delegate this activity to another station, which will be reported before the Exercise.
  3. The Control Station will identify itself and ask on frequency for stations willing to be present in the Exercise.
  4. Given that it is an Emergency Communications Exercise, the retransmission or “bridge” mode must be used whenever necessary, because if someone wants to be heard by the Control but cannot achieve it, it is important that its presence is acknowledged and its message arrives and is recorded, according to the objectives of the Exercise mentioned above.

Information to be transmitted

Stations reporting in the Net will send to the Control Station their Callsign, Name and Location (location and province, department or region).
