Sound the Alarm Project.

Red Cross “Sound the Alarm” Project
Saturday, Oct 14th from 0830-1230L

The Sound the Alarm Project (STA) is sponsored by the American Red Cross (ARC) and will work & operate in the Washington Hills area (adjacent to Highway 58, east of Elder’s Ace Hardware).  The Chattanooga Amateur Radio Club is proud to be the communications partner for with ARC.

The Fire Department has statistically identified the Washington Hills area as having an above average number of house fires. One house fire can consume a block of houses. The Red Cross STA Program offers residents free smoke alarms and will replace existing alarms with new ones and fresh batteries. To implement the STA, Red Cross Volunteers in teams of 2 will go door to door, offer and install the alarms.

A radio operator acting as a data collector and reporter will accompany each team. Data collected will be analyzed to find residences that are high risk, would not accept an alarm; vacant property; “bad” dog locations, i.e., could not approach; evident fire hazards, etc. The analysis will allow the Fire Department to make targeted “educational” visits to the houses in question. For radio operators, this will be community service, relationship building, practice at reporting data as if there was a disaster, and also a radio comms exercise.  We anticipate the need of 15 radio operators with HTs.

And That's The Way It is:

Congratulations to NGGMRS!

2023-06-09.  We congratulate the North Georgia GMRS Network for another linked GMRS repeater coming on-line today.  Fort Mountain (near Chatsworth, GA) is now available for use and is included in the Chattanooga Regional Skywarn Network.

Visit the NGGMRS Website to learn more about how GMRS Radio can help you and your family.

Please Note The Following:

Construction at the site of the CARC Lookout Mountain Repeaters has, as of this morning, 2023-05-10, required the temporary shutdown of the following repeaters:

  • 145.390 CARC Repeater
  • 444.100 CARC Repeater

The 146.610 Repeater remains operational on Signal Mountain.  Please note that the 146.610 repeater requires a 107.2 tone on both transmit and receive.

We regret this inconvenience, but this is a circumstance of which we have no control.  We have received approval to return these two repeaters to service upon the completion of construction in 90–120 days.

Thank you for your understanding.

While soldering methods may have changed over the years, the basics of soldering remain the same.  Hams can still learn a “thing or two” about soldering from this 1944 training video.

You Can Be a Helping Ham

Not only are Amateur Radio Operators known for helping each other (Elmering), we help our communities with Public Service even when disasters have not occurred.  This great video provides insight as to why we do what we do for the good of our nation, our communities, and our neighbors.  This video references a popular event in the Upper Penisula of Michigan.

So, if you live alone, you are disabled, if you need some help with a chore, or you’re just wanting someone to check in on you, then this net is here for you.

Join us nightly on the Chattanooga TN repeater 146.790 or on Echolink Node 79190.

To learn more, visit their website.

Club members David Dickey, KN4TEM, and Dale Wykoff, N5EIA, gave an excellent presentation on digital modes at our August club meeting.

It was a perfect blend of a digital overview, comparisons between modes, and probably best of all, a successful, working, homebuilt & home-designed Winlink interface between a computer and a Baofeng HT radio.

After the main presentation, David & Dale demonstrated the working Winlink client station by connecting to a Winlink gateway about 12 miles away.

Their presentation is available for viewing here.  We hope you enjoy their great presentation.
