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)

System Update Notices
The N4LMC 144.920 analog repeater system located on the north end of Signal Mountain, TN will change beginning January 7, 2022. At that time there will be a new offset transmit / receive frequency assignment and a move to DCS rather than CTCSS. The repeater output will remain on 144.920 mhz, but the repeater receive will change to 147.420 mhz. This would be a positive 2.5 mhz offset. The 146.2 CTCSS (PL) tone will change to a DCS code of 073 (encode/decode). So to sum up, the system will be as follows:
- Repeater TX: 144.920
- Repeater RX: 147.420
- Offset = +2.5 mhz
- DCS Code: 073 on both encode/decode
Make sure that you setup or change your radio and/or base station accordingly. There will be a recurring announcement on the system until we feel like everyone knows about the change.
The N4LMC 442.650 digital repeater system located on the south end of Lookout Mountain, GA will no longer broadcast the ARRL Weekly News on Sunday evenings and the Amateur Radio Newsline News on Friday evenings as of April 18th, 2022. The news broadcasts will move to the W4GTA 145.350 repeater system beginning the week of April 18, 2022. The N4LMC 442.650 will begin full time digital the week of April 18, 2022. Hear both newscasts on the N4LMC 144.920, 146.640, 224.560, the W4GTA 145.350, the N4BZJ 147.135 and the KB4ACS 444.700!

Other repeaters and/or rooms, reflectors, talk groups can be linked in. If you have a repeater system, room, reflector, and / or talk group that links in, let us know and we will mention it on our weekly net!
See LMARC’s Net page for information on all the nets that our systems carry that you can join in on. Join in on these nets, they won’t exist without participation and interest. Many of these nets are also looking for Net Control persons and Alternate Net Control persons!
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”!
