N4LMC – Lookout Mountain Amateur Radio Community

 

We strive to provide all modes of communication to the HAMs 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 call sign is a “club call”.  Beyond that, no we’re not!

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 belongs 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!


YAESU ANNOUNCEMENT: The Official Yaesu USA digital only net will be on Sunday April 7th at 4pm – Eastern, 3pm – Central (2100 UTC).

This is a Yaesu System Fusion digital voice net only. This means no links, bridges, or crossovers to other networks or modes.  I look forward to hearing you all this Sunday, March 3rd at 4pm – Eastern, 3pm – Central (2100 UTC) on the N4LMC Wires-X Systems!


2019 Winter Field Day is in the books!

We had an awesome time at Gifford Farms, the adults and the kids!  Thank You as always Jim Gifford, KM4MPF!

Winter field day was a huge success.  Cold temperatures did not discourage the local hams from gathering for some food, fellowship and fun.  A special thanks to Jim Gifford, KM4MPF, for organizing and coordinating the event.  Not to mention the amazing food he and Wayne James, WB4IEJ, bbq’d up.  Events like this take many hands to make them work and while we can’t list everyone who helped, each person who participated contributed toward making this Winter Field Day such a great event.

Weather conditions allowed for contacts all across the globe with better success on 80 meters at night.  At the event over 75 contacts were made working 3 stations.  One station was connected to a dipole antenna and was used on 20, 40 & 80 meters.  A full metal jacket antenna, by Alpha Antennas, was used on 20 & 40 meters and Michael Ashmore, KM4LVX, had his horse fence (yes, that is correct… ask Michael!) antenna running his station on various bands.  Official results have not been calculated for the exact number of contacts made, however, Rich Wagner, KC4IHO, made sure our young Trail Life boys participated and even recorded at least one contact.

Thanks to all who participated to make this Winter’s Field Day so memorable!

We’re putting some pictures up here.  If you have pictures you want to share with us, please contact Emmett Perdue (W4EDP), Jim Gifford (KM4MPF) or Terri Perdue (N9ZEN).

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!

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