Shape Shifting For Antennas

Here is an interesting video! Normally, when you want to adjust the resonant frequency of an antenna, you add electronic components like inductors to the circuit. But you can only go so far with that approach; at some point you’ll have to change the physical length of the antenna. That’s fine if you’re designing something, but impractical to do on the fly—until now. Researchers at North Carolina State University in Raleigh used liquid metal to construct an antenna that lengthens or shortens on electronic command.

Wiring and Grounding Info Link

Hello SEKARC and Friends...

While pondering my mobile power problems, I came across a webpage that has the most incredible "Do's and Don'ts I have ever read..  There are so many safety factors involved in the use of high current radios of today both fixed and mobile installations.  This guy covers the gambit of all mobile and fixed station wiring situations with recommendations.  He identifies products and wiring suggestions to maximize our safety in using high current radios.   Some of his points are so staggering and completely contrary to what I have always believed about mobile and fixed station power requirements.

Digital Mode Reference

Thanks to Steve, N5SD for this link, and he requested that it be shared with the group! Here is a great link to help you learn more about most of the digital modes and you can also HEAR the modes which is VERY helpful!

Special Thanks to Max McCoy !!

Max McCoy KCØMAX

SEKARC would like to thank our special guest presenter Max McCoy. At our October meeting Max gave a wonderful presentation on his trip down the Arkansas River in Colorado.

It was a fascinating look at the adventure and was complete with building the kayak trailer to building the QRP rig he used on the river banks. Beautiful photos and interesting stories, from involuntary swimming to the lopsided ratio of effort per QSO!

 We had a great turnout and another special visitor that stopped by was Joplin Hamfest Guru and JARC VIP Jim Scott. It was great to see Jim and we talked about the possibility of doing some joint meetings with the Joplin club in the future! Most of the breakfast casserole and all of the donuts were consumed, we all learned a lot and had lots of fun and if you missed it, make it to the next one!!
