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.

Eagle Scout Project

The Chattanooga Amateur Radio Club encourages your participation in a new Eagle Scout Project which is aimed at mapping “radio friendly” areas in and around the North Chickamauga Creek Gorge.  This beautiful and scenic area of Hamilton County is popular with hikers but can rapidly become a difficult area in which to locate anyone injured in the rugged terrain.
Stephen Hamill, KN4NSZ, Eagle Scout Candidate, says:
“This Eagle Project will be around the area of the North Chickamauga Creek Gorge and will be testing different spots to pass traffic in and out of the gorge for fire, EMS, and rescue personnel.  Scouts will hike the gorge and have a fox hunt-like transmitter.  Those assigned to listening posts around the gorge, will monitor the signals transmitted and document the signal strength at their specific location and other pertinent information.
It is suggested that you use mobile radios and set the “receive” frequency to 146.540 MHz (fox hunt transmitter) and 146.530 MHz (Simplex) for talking with the listening stations and checking in with them.
The project will start on 9:00 AM EDT Saturday, May 22nd .   Listening stations will be assigned to different locations around the rim of the gorge area.  Those wishing to participate should contact me at via email to be assigned to a specific location.  Make sure to bring writing supplies to document reception at your assigned location.
The project will last no longer than 5 hours but bring your own food, snacks, water, meds, etc.
If you have any questions, please contact me directly via email:  Stephen Hamill, KN4NSZ,”

Field Day 2021

ARRL Field Day 2021 is just around the corner.  Field Day (FD) is Saturday, June 26 – Sunday, June 27.  Setup activities begin around 9 AM EDT on Saturday.  Official operations begin at 2 PM and continue through 2 PM on Sunday.  Teardown begins shortly after 2 PM on Sunday.

The tentative location for our field day is Camp Jordan Pavilion (across the street from Camp Jordan Arena).

Previous plans for this year’s FD are being revised in view of State and Local relaxations of  “COVID-19 protections”.  All are welcome to the event and we hope to have a renewed emphasis on Scouting this year.  If you would like to help with the Scouting side of FD, please email Mark Rose, Club President (

FD day provides a welcomed relief to the “cabin fever” of the past several months and is an excellent way to introduce folks to Amateur Radio…so volunteer if you can help and bring along those that may find ham radio interesting, fun, and a way to provide service to your community.
