For anyone in the Chattanooga, TN region, the North Georgia GMRS hosts a weekly Skywarn training net Tuesdays at 7:00 pm Eastern time. Licensed GMRS operators, who are not NGGMRS members may join as guests.
You can see the repeater locations, frequencies and tones at
www.nggmrs.org. For this net, all repeaters north of Fort Mountain are unlinked from the rest of the network. (i.e Ft Mtn, Chatt 700, Lookout Mtn, Ooltewah, Georgetown, White Oak and Cades Cove become their own linked group.)
