January GARA Meting: Antenna Design with Roger Stout, N4RWS
I became fascinated with antennas in a UHF/ Microwave course many years before being licensed as KC4YLQ in 1991. (now N4RWS). I've been privileged to work in areas that continued to pique my interest having spent nine years with Bell Labs. While there I had the honor to work in a 60 man department which included Phillip Smith just prior to his retirement. Needless to say I felt an obligation to learn to use his brainchild the Smith Chart. Thank goodness for the tutorials which were in the back of the "old" RCA tube manuals, I read the examples till the pages fell out. My last 40 years of employment was with Gilbarco here in Greensboro. ...

October GARA Meeting – Battery Management
This month I will be talking about a battery management project I am working on for a set of LiPo batteries to power a portable station. The goal is to monitor the status of each battery in the set and to automatically switch a battery to a solar charger or to the radio as needed. I built a manual system to do this, but now I want to automate it. I hope you find it interesting.Also, winter Field Day is coming up, so if you are interested, please let me know. I will discuss it at the meeting. Several of us participated in last year's event and had a good time, so I hope you will consider helping out this year. 73,David McLin, AC4A

September GARA Meeting – Inexpensive VNAs in Action
A number of club members have recently purchased a vector network analyzer called “NanoVNA” off of eBay and we will be demonstrating how it works and measuring various antennas to show how well they’re tuned. These devices can measure many different electrical parameters including complex impedance, reflected power and SWR to show you the performance of your antenna or antenna system. If you’d like to see how your antenna stacks up, bring it along! This will be a fun and educational demonstration of an inexpensive piece of measurement equipment at work.
Update: here is the link to the NanoVNA on eBay if you are interested in purchasing ...
August GARA Meeting
Have you ever wondered what it takes to coordinate a large, international, and dangerous trip to a remote location so that other hams can add that new entity to their QSL lists? The 2015 Navassa Island K1N DXpedition is a great example of how to raise funds, coordinate activities, and run a successful trip. Come and visit GARA at its new meeting location (Sarah's Kabob Shop in Greensboro) and watch a video talk together with us as we learn about this important event and how it happened.
Come at 6:30 to eat, and the meeting will begin promptly at 7:15.
Meeting Location and Info
GARA Meetings are Moving!
It's been a while since GARA changed meeting locations, but considering the challenges we faced at our old location, the Board decided it was time for a fresh start. A number of GARA members, as well as some Board members, suggested trying Sarah's Kabob Shop taking into consideration the way food is ordered, the available meeting space, the restaurant's location, and other factors. After talking to the owner and getting the meeting times on their schedule, we're happy to announce the new location. Meeting times and format will remain the same. Thanks for helping us to make this a successful transition!
Field Day is Almost Here!
Field Day 2019 is just under a week away. We hope you can participate this year. Setup will start Friday afternoon at 1300, June 21, with operations starting 1400, Saturday, June 22 and ending 1400, Sunday, June 23. We will be running completely off of solar power this year, so if you have any interest in solar setups, batteries, charging and other equipment, this is a perfect opportunity for you to learn a lot!
Tell your friends! There will be a Get On The Air (GOTA) station available for new- and non-hams to try their hand at making HF contacts. You'll want to bring people along with you to discover all of the fun that amateur radio ...
Blue Ridge Microwave Society
There is a new local ham organization dedicated to microwave work: the Blue Ridge Microwave Society (BRMS). This group is to promote VHF/UHF and Microwave activity with emphasis on frequencies above 1 Ghz. This group is new so there's not too much on the site yet, but there are a number of ham currently active on 23 cm, 6 cm, and 10 ghz who would like to promote more activity on the microwave bands. The BRMS just recently put together a group page located here:

April GARA Meeting: Field Day Planning
It's time to start firm up our plans for Field Day. For this month's presentation, I will cover what has already been done, this year's rules, and what we need to do to get ready. I hope you will be able to participate in this year's Field Day.
At last month's meeting, I mentioned a few possibilities for other club activities throughout the year, and I would like your feedback or suggestions so we can start planning.
I hope to see you at the meeting.
