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 www.neighborhoodlink.com/RTC-TH_Tech/pages

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:

To access the lessons, visit www.neighorhoodlink.com/org/rtcth, 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.

It's taken nearly 2 years to put up this light-weight mast in the backyard of our "town" site station. The "tower-like" base section is a salvaged TV antenna base from the second floor balcony when we did minor remodeling of the house. Originally I was hoping to set this up at the farm. But plans changed and things got side tracked.

This past week, all the odds and ends came together, and I added a 6m length of steel pipe, a PVC yardarm, and made use of some "old" stainless steel fittings / hardware from my sailing days.

Max height is 9.6 m AGL (above ground level). The yardarm normally rests at about 4.5 m AGL. Each end of the yardarm has a S-hook fitting to allow connecting another halyard truck. The main halyard hoists the yardarm and can also hoist an item. So there are 3 possible lifting points with all able to attain a maximum height of 9.6 m AGL. (See a photo of the mast installation in progress in "My Pictures."

The tower section frame is embedded in a tractor tire filled with concrete. The estimated weight of the tractor tire base is about 325 kg. Right now, it is intended to be a free standing mast. The main purpose was hoisting antennas for testing / tuning. I didn't intend to mount any antennas permanently to the mast (but who knows, things can change).
