· Emergency Comms, HF · Greg, G0DUB

An earthquake today at 12:19 UTC has caused severe damage in Petrinja in Croatia. The town is about 50 kilometres from the capital Zagreb. The neighbouring country Slovenia has shut down the Krsko nuclear power plant as a precaution. The earthquake reached a magnitude of 6.4, the epicentre was 46 kilometres southeast of the capital Zagreb, the Seismological Centre for the European Mediterranean reported on Tuesday. Initial reports spoke of major damage. The town of Petrinja, which has about 25,000 inhabitants, was affected. Roofs, facades and entire buildings collapsed, it said.

All services engaged in the earthquake-affected area are reported to be organised and have their own communications.

This earthquake is one of many in recent days and the national society HRS is asking members to be close to their radios and a net is formed on 3.675MHz as well as DMR and repeaters in case any assistance is needed.

IARU speaks at ATU Workshop
· Emergency Comms, Spectrum · Sylvain, F4GKR

IARU was present at the recent ATU African Telecommunications Union / ICT Day 2019 Commemorative Workshop — “Using Technology to Save Lives: Emergency Communications for Disaster Risk Reductions and Management”. The Workshop was held in Maputo, Mozambique and IARU was represented by Brian Jacobs, ZS6YZ and Leon Lessing, ZS6LMG. Brian presented an overview of the amateur capability for emergency communication and some of the pre-conditions for it to be effectively deployed. He also gave a second presentation on the IARU STARS program, which seeks to support and encourage the growth of amateur radio in countries where it is not well established. 

Both presentations were well received, and gave rise to extended discussions about the public service role of amater radio and its role in developing the national skill infrastructure.

Emergency Communications Meeting — Friedrichshafen 2019
· Emergency Comms · Greg, G0DUB

The 44th HamRadio Exhibition at Friedrichshafen attracted 14300 visitors, among them around 27 Emergency Communicators from 14 countries who attended the IARU meeting for Emergency Communicators on Friday 21st June.

After the introduction and Region 1 report, there were interesting presentations followed by a good exchange of information in an Open Forum session which carried on beyond the official closing time of the meeting.

Mike SP9XWM and Cris SP7WME spoke about the use of new technology in exercises in Poland. There was then an Open Discussion on what use we could make of Satellites and other new modes for Emergency Communications. Discussing Low Earth Orbit as well as Geostationary satellites, HF conditions and weak signal message modes ( e.g. JS8call ).

Alberto IK1YLO spoke about the NEIFLEX ( North East Italian Flood Exercise ) European Exercise of 5⁄9 June 2018 followed by an update on their national DMR project. Ron 4X1IG presented on how emergency communications as being grown in Israel by using a ‘Contest as a drill’.

Oliver DL7TNY provided an introduction to AREDN data networks which got many attendees to look at the networks in practice on the DARC stand in the main hall.

An Open Forum was then followed by a short exercise on how we may respond to a power grid failure. 

The presentations where possible are available at the bottom of this page with the content being the opinion of the presenters.

The next Ham Radio on the Bodensee is on June 26 – 28 2020 and will include another emergency comms meeting.
