N4LMC – Lookout Mountain Amateur Radio Community


We strive to provide all modes of communication to the HAM community in Chattanooga, TN, NW GA, NE AL and surrounding areas.  There are so many different bands and modes, we concentrate on the repeaters and nodes because that’s the part of the hobby that we love being involved in.  We want to bring the connected analog and digital modes to the areas around us that have not had access in the past.  Our vision is to enhance amateur radio by positioning a variety of equipment throughout the area.  We work with local enthusiasts discussing theories, communication models, types of equipment, gadgetry, and more.

Are we a club?  That depends on how you see things.  We are a club by ARRL / FCC definition.  We do meet the minimum requirements and the N4LMC and KO4GVX call signs are “club calls”.  Beyond that, no we are not.  We do not have paid members, we are a group of people who care about growing Amateur Radio, especially the digital modes and helping our community by utilizing our hobby!

Our website offers a wide variety of information.  New information and resources are being updated and/or added all the time.  Take a look at the Main Menu and just drill down through all of the choices to check out what we have to offer.

At this time we offer a wide variety of repeaters and nodes that encompass Analog as well as Digital modes.  Our repeaters run under several call signs.  N4LMC and KO4GVX belong to the Lookout Mountain ARC, W4GTA belongs to the Tri-States ARC, W4PL belongs to the Chattanooga Old Timers ARS & W4RRG belongs to the Rebel Repeater Group.  All of these are calls that I/we are authorized to use by those respective clubs and/or trustees.  A HUGE Thank You to all of them!

We are also available via HamShack Hotline at extension #12560.  (please respect that we are in the eastern time zone if you call, leave a message if no one answers, we will call you back as soon as possible)

A brief note: The key to success on the air is described by one word: Courtesy.  There’s no other way to explain how hundreds of thousands of Amateur Radio Operators can share the same radio frequencies all over the world with minimum interference and conflict.    If you keep courtesy at the front of your mind you’ll rarely have difficulty on the air.  An attentive and courteous operator is welcome on our systems, “It’s not the class of license the amateur holds, it’s the class of the amateur who holds the license”!

With that said, we really want YOU to have fun and enjoy this hobby!
