ARRL Field Day
Saturday, June 24 – Sunday, June 25, 2023

Come One – Come All
We’re having a party! And calling it ARRL Field Day (FD) 2023!

Come on out for a weekend of fun and frolics. Operate a little radio. Enjoy some fellowship. Have some good EATS! Starting Saturday morning any time after 8AM EDT at Shelter #2 in Chester Frost Park with a bit of exercise (otherwise called putting up antennas and running some coax) and any general site prep we may need to do. Then we break for a short training session on Field Day operations and relax with some BYO lunch.

At 2PM EDT, FD officially starts, and we’re off and running. We plan on setting up a couple of “Quick Field Antennas” for demo purposes, and maybe we’ll see how they play on the air. We might have a solar station too for some bonus points (think of it as extra chocolate sauce on your ice cream!) just to show how it can be done with not too much effort.

Dinner provided by CARC sometime around 5PM, menu is still pending as we need someone to step up as “Chef”.

We will play radio all night, propagation of the bands permitting, and through Sunday morning. A bit of breakfast Sunday and then a “Winding Down” lunch around Noon, again provide by the Club.

CLICK HERE to sign up for ARRL Field Day 2023. Even if you have already made me aware of your desire to participate, please fill in the form so we’ll have a complete list with all your information.

By 4 PM Sunday we should be all cleaned up, wiped down and on the road home.

Please come on out for a bit of outdoor fun! If you have questions, please email me at

Thank you.

Manager, CARC-ARRL Field Day 2023

Please Note The Following:

Construction at the site of the CARC Lookout Mountain Repeaters has, as of this morning, 2023-05-10, required the temporary shutdown of the following repeaters:

  • 145.390 CARC Repeater
  • 444.100 CARC Repeater

The 146.610 Repeater remains operational on Signal Mountain.  Please note that the 146.610 repeater requires a 107.2 tone on both transmit and receive.

We regret this inconvenience, but this is a circumstance of which we have no control.  We have received approval to return these two repeaters to service upon the completion of construction in 90–120 days.

Thank you for your understanding.

While soldering methods may have changed over the years, the basics of soldering remain the same.  Hams can still learn a “thing or two” about soldering from this 1944 training video.

You Can Be a Helping Ham

Not only are Amateur Radio Operators known for helping each other (Elmering), we help our communities with Public Service even when disasters have not occurred.  This great video provides insight as to why we do what we do for the good of our nation, our communities, and our neighbors.  This video references a popular event in the Upper Penisula of Michigan.

The Lone Ranger Wellness Net

The net was created as a daily check-in for members of the amateur radio community, no matter their QTH, who wish to have someone check in on them to make sure they’re OK. So, if you live alone, you are disabled, if you need some help with a chore, or you’re just wanting someone to check in on you, then this net is here for you.

Join us nightly on the Chattanooga TN repeater 146.790 or on Echolink Node 79190.

To learn more, visit their website.

Club members David Dickey, KN4TEM, and Dale Wykoff, N5EIA, gave an excellent presentation on digital modes at our August club meeting.

It was a perfect blend of a digital overview, comparisons between modes, and probably best of all, a successful, working, homebuilt & home-designed Winlink interface between a computer and a Baofeng HT radio.

After the main presentation, David & Dale demonstrated the working Winlink client station by connecting to a Winlink gateway about 12 miles away.

Their presentation is available for viewing here.  We hope you enjoy their great presentation.
