Join Jim Gifford, KM4MPF as Net Control and get in on the fun!

This Net is an open Net and is not affiliated with any club.  All properly licensed HAMs are welcomed and encouraged to join us!  We usually have between 60 and 70 check-ins, and our goal in 2021 is to grow that to 80+!

The Sunday Night Net, broadcast from Chattanooga, TN, generally follows the schedule below, but at times we do move things around to accommodate something.

The Net is held every Sunday evening beginning at 2000 (8pm eastern time).

Curious about Slow Scan TV?


We started in June of 2019, and will be sending a Slow Scan TV photo out via all the repeaters we are connected to.

If you ever wanted to know more about Slow Scan TV, now is your chance to get in on the fun and learn!  We play on 145.800 after the net.

It takes about 1 minute and 52 seconds to send a picture (of average size) around the world or around the block on most any radio using slow scan tv and it will be received as clearly as the picture to the left, or even better under good conditions.  Conditions and your setup can make huge differences in quality.  See the images that we’ve transmitted in our photo gallery.  If you are trying to answer a puzzle, send us an email at!

Current SSTV image is from the SNN net on 2023-12-03 – Answer to last weeks image (2023-11-26): Ice Cream Sundae (10 correct, 0 incorrect)


Occasionally we will have a ‘bonus’ or additional picture that we send towards the end of the net, we will post it here as well as add it to the pic album.




Want to see this in action, check out this video recorded live!  The actual picture transmission starts at about the 1:20 mark in the video.  Note, this is a large file and may take time to download/buffer and start, so be patient.

Problems watching or seeing the video?  Here is a direct link to the video on YouTube.

VE Testing


Want to test for your first license, or maybe you want to upgrade from Tech to General or even go all the way to Extra!

We’ve got you covered.  There are tests available in the area at most any given time.  While pre-registration isn’t required, it is definitely best to let us know ahead of time if you want to test and what you want to test for so that we can be sure to have the needed resources on hand to take care of you.


Please Note:

  • That if you choose not to contact in advance, there is no guarantee that the test will take place or that your particular needs can be met.
  • The FCC requires a FRN number!  You will not be able to test without one, no exceptions can be made.
  • The FCC requires a valid email address!  You will not be able to test without one, no exceptions can be made.
  • The fees collected go directly to the ARRL and the FCC.  The VE testing entity does not keep even 1 cent and even absorbs some costs!
  • The Tri-States ARC will pay the $5 fee for 17 and under age testers.  The ARRL reduces the fee, the club picks up the rest, test is no cost!
  • The Sunday Night VE Team will pay the $5 fee for 17 and under age testers.  The ARRL reduces the fee, the SNN picks up the rest, test is no cost!


If extreme difficulties exist that prohibit you from utilizing one of these sessions, such as permanent work schedules, etc, use the Contact Page here and give us as much information as possible.  We will attempt to help you in any way that we can.  This is provided on a case by case basis, and is only for hardships beyond a persons control.

There will be a November class for those wishing to study and test for their Technician license.  Currently, we do not have a cost for the study materials, that will be announced here and on the net as soon as we have more info (will be roughly $20).  There will be the ARRL test session fee of $15 payable to the ARRL as well as the FCC $35 license fee which will be administered by the FCC.  See below for the schedule and location information.
