Our May 12 speaker will be Kristen McIntyre, K6WX, who will speak on the topic of “SWR — Who Cares?” And will debunk some of the misconceptions and misunderstandings regarding the widest used measurement in ham radio — the Standing Wave Ratio. Topics covered will include what it is, how it is calculated, what SWR actually measures, and what we should care about – including what an impedance match is, the impact of SWR on real transmission line loss, how to match a transmitter to a load and how to measure feedpoint impedance. I’m looking forward to learning a thing or two!
Kristen has been interested in radio since she was about 5 years old. She started in Amateur Radio in 1979 getting her ticket while at MIT. Kristen has worked in many diverse areas from analog circuit design to image processing to starting and running an ISP. She is currently working at Apple in Core Networking, and spent many years at Sun Microsystems Laboratories where she was researching robustness and emergent properties of large distributed computer systems. She is a long time denizen of Silicon Valley and has worked at or consulted for many of the usual suspects. Kristen is an active ham and loves to chase DX on HF with her Elecraft K2 which she built while visiting her mother in Florida. She is ARRL Pacific Division Vice Director, president of the Palo Alto Amateur Radio Assoc., the Q&A columnist for Nuts and Volts magazine, and is active in many local clubs. Kristen was recently inducted into the CQ Amateur Radio Hall of Fame.
