Carribean Tropical Storm Earl - Emergency activities

Tropical Storm Earl is currently heading across Central America affecting the countries of Honduras, Guatemala, Belize and Mexico. IARU Region 2 has requested that attention is drawn to the following frequencies used by nets in North and Central America to track and deal with the consequences of these severe weather events. Radio Amateurs in Region 2 play their part in gathering and distributing information for the weather and emergency services as they do every year.

Radio Amateurs in Region 1 are reminded it is possible to cause unintentional QRM to these nets so please listen carefully if operating near these frequencies which have alerted due to Tropical Storm Earl:

Mexico: 7.060 & 3.690 MHz
Guatemala: 7.075 MHz
Belize: 7.177MHz
USA Hurricane Watch Net: 14.325 MHz

For the remainder of the Atlantic hurricane season, Radio Amateurs are reminded of the following frequencies which have been notified from previous seasons:

Caribbean Emergency & Weather Nets: 7.162 & 3.815 MHz
Eastern Caribbean Narrow Band Emergency System Net: 7.036 MHz USB (Olivia & MT63)
Caribbean Emergency: 14.185 MHz
Republica Dominicana: 7.065 & 3.780 MHz
Cuba: 7.045, 7.080, 7.110, and 3.740 MHz
Central America: 7.090 & 3.750 MHz
Nicaragua: 7.098 MHz
Panama: 7.085 MHz

Maritime Mobile Service Net: 14.300 MHz
Salvation Army Team Emergency Radio Network (SATERN): 14.265 MHz

Other local emergency communications groups may also activate if a hurricane approaches their area and those frequencies would be announced at the time.

Hams ready for Philippines typhoon

The following information was received from IARU Region 3 on Friday morning. With poor propagation, please take care in the area of known Philippines emergency communications frequencies.

"Ham Emergency Radio Operators (HERO) was set this morning at 2145 UTC ( Thursday UTC Time ) due to Super typhoon Nepartak amplifying the effects of the SW monsoon. Heavy rains in some areas caused preemptive school class suspensions.

HERO net operator DV7DRP opened DU net on 7095kHz at 2300 UTC ( Thursday ) with relay net controls DU1IVT, DU7DUG, and DU1EQ. PROPAGATION CONDITIONS NECESSITATED RELAYS AND HAND OFF OF NET CONTROL DUTIES TO DU1VHY.
Rainfall of varying intensity were reported but mostly minor floodings on the streets.
Reports of river conditions in the metro Manila area was also being reported with the Marikina River being at 13.7 meters in depth.
In general, rains are in the central Luzon and Metropolitan Manila area.

Emergency Comms activities at Friedrichshafen 2016

The 41st HamRadio Exhibition at Friedrichshafen was also the venue for two meetings for Emergency Communicators which were well received.

On Friday 24th June, the first IARU Region 1 Emergency Communications meeting was held in the English language with an average 20 attendees from 10 countries covering a wide range of topics from reports from other regions, proposals to change the IARU Emergency Message procedure and information on the Emergency Communications Groups in Germany, Poland and Slovenia. The presentations are available on the following links;

Region 1 Report, Message Procedure proposals, GlobalSET 2015 - what next?. SP Emcom , DARC Emergency Communications, EmComm in S5 and Ice Sleet Intervention

On Saturday the 4th DARC Notfunk Universitaet took place with many presentations on skills and techniques in the German language. A report and some of the presentations are available at;


Planning starts now for Emergency Comms activities at the next Ham Radio on July 14-16 2017.


Radio Amateurs involved in Cyprus forest fire response

Radio Amateurs in Cyprus are currently active in emergency activities tackling the biggest forest fire the island has ever dealt with in the Solea region. Activity is currently using only the VHF band, mainly the local RV48 (R0) and RV58 (R5) repeaters. Hams in and around Cyprus have been requested to keep clear of these repeaters to aid the emergency communications activity.

Fire fighting forces are deployed around the perimeter of the fire. The main fronts of the fire are active, but due to high winds and very high temperatures, the effort to extinguish the fronts seems mammoth. Thick smoke is complicating the task. In addition to the ground forces, a total of 16 aircraft are also operating, with aircraft coming from Israel, Greece and later today France and Italy.

It is estimated that some 20-25 sq km of forest have burned so far, while 4 villages are in grave danger of destruction, as fires are currently located on their perimeter.

Unfortunately two fire fighters have lost their lives in the line of duty, while another 2 are seriously ill in hospital. Cyprus frequently suffers forest fires during its hot summer months, but these are believed to be the first firefighter deaths for years.

Netherlands/Belgium 'Power Failure' Exercise 8 June 2016

On Wednesday 8th June between 1800-1930UTC Radio Amateurs from the DARES Emergency Group in the Netherlands and B-EARS in Belgium will be taking part in an exercise simulating a Power Outage in the south of the Netherlands and part of Belgium. In the exercise scenario the groups have been requested to provide welfare and secondary communications links between North Brabant ( near Eindhoven ) and the rest of the country.

The exercise will test the ability of the groups to set up a wide area VHF and a HF network on the planned frequencies of 7065 kHz ( Primary ) and 7110kHz ( Secondary ). The 7065 kHz frequency being needed as Novice Licences in the Netherlands ( PD ) are not allowed to operate above 7100kHz. Operations will be mostly voice but Winlink/Digital modes may also be used.

Radio Amateurs are asked to keep those frequencies clear for the time of the exercise.

Full information ( In Dutch ) is available on the DARES website at http://www.dares.nl/nieuws/245-oef-power-outage .
