Savannah and Charleston are on SB44 on 129W on transponders 9 and 11. See what signal strength you get on 129 for those transponders. Go Menu 6 1 1, change the sat to 129W, and then change the transponder to the number desired.

You're on the edge but probably will get a decent signal strength.
You're also in SB50:

SB50 currently carries New Orleans on T10.
You may be in the fringe for SB43, carrting Atlanta on T4 and three of the Monty locals on T8:

If you have a 61.5 dish see if you have any signal strengths on that sat for the lower transponder numbers (one through fifteen).
