My Ham Radio Interests
Emergency preparedness / communications, Weather observation

Free Emergency Preparedness lessons series: Several parts (i.e. Lessons 1-6, 9-10) of the 12 part series have been released. Although created originally focusing on natural disasters relative to Nan Province, Thailand, some of the information is general and can be readily adapted to other areas. For example, water is critical in all disaster situations. The information on prepare and replenishing water supplies can be useful in most disaster situations. We hope to complete the remainder of the series in 2012. The completed lessons are available at

Free MEWS (Mobile Emergency Weather Station) and weather observations lessons are available at my website. MEWS enables amateur radio operators to make valuable weather observations in disaster areas where there are few or no working weather stations. These weather reports can help relief helicopters to know flight weather conditions in the disaster area. Relief coordinators can use the weather data to understand the situation in the disaster area to better coordinate logistics and supplies for survivors.

You can read about MEWS at the following links:
1) at

2) at

To access the lessons, visit, then go to the “Pages & Links” section, and click on “RTC-TH MEWS Lessons".

The lessons are in English. I welcome any help from other amateurs to translate these lessons to other languages.

Thanks for visiting my page. Best wishes to you.

Hamfest India 2013 "Next Gen EmComm: GECO" presentation


10/1/2013 2:48:27 PM (0 comments) Add a commentAdd Comment

I collaborated with Basappa (VU2NXM) on "Next Gen EmComm: GECO" (Next Generation Emergency Communication: Grassroots Emergency Communications Operations)which he presented at Hamfest India 2013 in Gwalior, India.

The key topics of the presentation included:
1) preparing and nurturing the next generation of EmComm operators;

2) improving rural education combining classroom lessons used for hands-on community service projects related to EmComm;

3) introducing a 3-tiered approach to help remote rural villagers developing an EmComm system using non-radio ground-to-air signals, CB radios, and amateur radios;

4) suggesting possible methods to implement the program combining and sharing resources between ham groups / clubs, villagers, government agencies, and non-government organizations.

Next Gen EmComm: GECO is directed to remote rural villages in developing countries. These areas tend to be impoverished. So low tech / no tech methods are easier to implement. However, the power of natural disasters can quickly reduce places in highly developed countries to third world conditions (e.g. Katrina and Sandy or the Haiti earthquake come to mind). These harsh conditions require EmComm systems and procedures to be robust and simple. These considerations assure grassroots EmComm can be effective when needed.

Due to time constraints, the presentation had to be abridged. Both the abridged and full versions can be viewed at

Non-Radio Ground-to-Air Signals: Three separate lessons were spun-off from the Hamfest India 2013 presentation. These are also available using the link above.

I want to thank Basappa VU2NXM, and Jayu VU2JAU for the opportunity to contribute to Hamfest India 2013 and to share these ideas with Indian hams.
