Hi Pantherpaw9, The 4Seasons repeater is not part of the North Georgia GMRS network so they would not be able to talk to you on the Sassafras Repeater. If they can reach the Pine Log repeater from their location, you would be able to talk to each other since the repeaters are linked. They may be able to reach Sassafras from there. I can not say for certain, but I think I am able to reach Pine Log from I285 and Roswell road. With out being in the area I can not remember, getting too old. Looking at the NG GMRS membership list it appears that you also got the Zello link and they could use that with their smart phones.
