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’re not, we are a group of people who care about growing Amateur Radio, especially the digital modes!
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!

ARRL Summer Field Day 2021! – Come take part in this yearly get together!
The Lookout Mountain Amateur Radio Community (LMARC) and The Sunday Night Net (SNN) is partnering with The Tri-States Amateur Radio Club (TSARC) to host the 2021 Summer Filed Day event this year. We will be providing a lunch Saturday afternoon and a dinner Saturday evening.
Come join in n the fun! There will be stations setup for contact on multiple bands, there will be multiple antennas to try out. There will also be a Get On The Air (GOTA) station where non HAMs can see, touch and even get on the air! Bring your friends and family, let’s have some fun! Please let us know if you plan to come and how many might be in your party so we can be prepared. Follow this link to let us know.
We’ve all been cooped up way to long, so this is not only a great way to get out and get together with our HAM families and have a fun time, it can also be a learning experience fo us as well as friends or family that want to see or learn about what we do including the play part and beyond to things like public safety, etc.
KM4MPF Sales will be there with live demonstrations on power alternatives such as generators, solar panels, Bioenno batteries and more. There will be demonstrations of antenna analyzers and how to use them.
Every June, more than 40,000 hams throughout North America set up temporary transmitting stations in public places to demonstrate ham radio’s science, skill and service to our communities and our nation. It combines public service, emergency preparedness, community outreach, and technical skills all in a single event. Field Day has been an annual event since 1933, and remains the most popular event in ham radio.
Join us for this fun event June 26th and 27th in The Cove! TSARC Field Day will be held at the Cedar Grove Community Center in beautiful McLemore Cove (click the link for Google Maps). The address is 5395 West Cove Road, Chickamauga, GA 30707. (be sure you put the word “West” in the address if you are using something other than the link above. That same address exists on Cove Rd and will mislead you!)
Field Day will start June 26 at 2PM , although we do need people showing up around 9AM to help with setup. If you can help with setup and / or tear down and clean up, please let us know by filling out the form here. It will run until 2PM Sunday June 23 and we will need people to stick around to tear down and clean up. See The Tri-States ARC Website for more info on this event.
TAG, which stands for TN, AL GA, is held each Wednesday night at 7:30 PM Eastern. This is a digital only net and is off to a great start!
Join the conversation on the TAG Multi-Mode Digital Net via SouthEast Link by using any of the D-Star, DMR, C4FM / Fusion / Wires-X, Allstar or Echolink nodes and / or repeaters listed above.
Monday nights at 8 PM Eastern on the W4GTA 145.350 repeater as well as other methods, see below.
Net control will usually be Terri, N9ZEN. This net provides a forum for Licensed Female Hams of all ages and ham experience to meet on the air for fellowship, to discuss common interests, to discuss technical topics, to learn how to prepare for emergency events and communications, and more! Be sure to check out our website located at tagylnet.org.
Be sure to check out the new page for the Chattanooga Sunday Night Net!
We will update the page with more information and new features as those are available, so check back often! Join the Net, just listen in if that’s what you need to do, and we hope you’ll join in on the fun soon!

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”!
