Welcome to the Sawnee Amateur Radio Association

SARA is one of the premier clubs in the North Georgia area. Presently, we have over fifty active members. The club and its members are actively involved in many different amateur radio activities. Some members enjoy just rag-chewing, or operating CW, SSB, VHF SSB, or QRP. Others enjoy chasing DX, or working satellites, or building equipment and antenna systems.

The clubs main emphasis is to assist local communities with special events and their communications needs. We also like to promote the public awareness of the ARRL Field Day event held every June. SARA has been honored with two national “First Place” finishes in our class, during past Field Day events.

If you are just starting out in amateur radio, we invite you to one of our upcoming events or meetings. Let us introduce you to our hobby while you visit one of the best clubs in the area.

More Information About Batteries Than You Thought There Was.

Tuesday July 11 , 2016  7:00 pm

Our speaker this month is Jim Krause, AB4CZ, an expert in batteries, those ubiquitous things we take for granted, but which are really more complex than we might imagine. Choosing the right battery for the application and the proper care and feeding of that battery are not as easy as it may seem at first blush. But Jim knows all about it. He tells us about himself:

First licensed in 1966 as WN4CZK, passed the Advanced in 1969 and Extra in 1987 when I changed my call to AB4CZ.BatteryMan I received my BSEE degree from Va. Tech in 1971. Worked as transmitter supervisor and chief engineer at 50KW WRVA, 200KW ERP WRVQ in Richmond VA, and in 1981 moved into circuit design with International Tapetronics in Bloomington IL, where I was involved in magnetic tape recording and digital audio for broadcast applications.

Moved to Atlanta in 1981 to avoid another midwestern winter and took a job with Lanier Business Products, where I developed hardware and software to support SMD disk drives on Lanier’s Z80-based small systems computers. In 1983 I left Lanier to work for Intecolor / Rockwell Automation where I was the video amplifier designer and analog design manager. In 2002 I joined Motorola Energy Systems Group where I was involved in the design of Li-Ion and NiMH batteries for various products. While with Motorola, I joined the Product Safety group where I was responsible for assuring that all battery and charger designs met Motorola’s redundant safety requirements. In this position, I was also responsible for root cause analysis of safety-related field returns. I got to blow up a lot of Li-Ion batteries to determine the limits of safe operating parameters. I retired from Motorola Solutions in 2014 but have since taken a part-time position as design engineer with NuGen Systems where I am involved in the design of LiFePO4 (Lithium Iron Phosphate) batteries for Automatic Guided Vehicles.
