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, W4RRG and KO4GVX call signs are “club calls”.  Beyond that, no we are not.  We do not have members (paid or otherwise), we are a group of people who care about growing Amateur Radio, especially the digital modes as well as 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.

We offer a wide variety of repeaters, nodes, links, reflectors, bridges, etc, that encompass Analog as well as Digital modes.  Our repeaters run under several call signs.  N4LMC, W4RRG and KO4GVX, all belong to the Lookout Mountain Amateur Radio Community.


LMARC and SouthEast Link

Important Announcements

 

SouthEast Link / LMARC DMR TalkGroup 43389 Change!

2024/07/21 – We had to make a change to support moving forward with new equipment and software!  This means that you have to make a change in your code plugs where SouthEast Link TalkGroup 43389 and any N4LMC or W4PL DMR repeaters are concerned!

Change ANY reference that you have where TalkGroup 43389 is concerned to TimeSlot (TS) 1.  TS2 will no longer carry TG 43389.

Please make this change immediately to keep your access to TG43389 working!


Hurricane Helene Update

2024/09/25 – We are expecting a major impact from Hurricane Helene (see here: https://www.nhc.noaa.gov/graphics_at4.shtml?start#contents) Thursday, Friday and possibly into the weekend in our area!

As of this posting we do not know the extent of impacts yet.  We are backed up by generator and fiber connections.  We do expect power issues, but hopefully no connection issues.  We will keep you up to date here as we know more.

We will be carrying the VOIPWX hurricane net on Allstar node 46292 as well as the Echolink Conference Server *SELINK2* (287616) beginning at 10AM eastern time Thursday Sept 26, 2024 through Friday when they close the net.

Stay Safe everyone!

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!

Also, one question we hear often is “why is N4LMC showing on my display and who is that”?  There are two reasons that the N4LMC call sign will show on your digital display rather then the person in the QSO.  N4LMC and KO4GVX are call signs that are assigned to LMARC.

  • They will show when the party in QSO is registered on one mode, but not the other (this is why we always say register for all even if you don’t use them).  So as an example, you are on YSF, you are in a QSO with someone who is on DMR, you do not have a DMR/CCS7 ID, since we must supply a call sign the N4LMC call shows up when you key up.  Want to change that, register for all digital modes, it’s free and easy!
  • The other reason you might see N4LMC or KO4GVX is that the other QSO party is coming in via a mode that does not support sending call sign data.  That could be a mode like Allstar, Echolink, HAMs Over IP, Hamshack Hotline, etc.

TAG Multi-Mode Digital Net

 

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.

 


TAG YL Net (TN, AL, GA)

 

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.


Chattanooga Sunday Night Net

 

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”!

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