Must be why I can't find it. lol. I will go over one. Does 83 have a strong transponder? Its not on the list. If not 85 looks to be my best satellite.
With USALS you don't need to set to the most southern satellite, you can choose any satellite that is close to south to simplify the process.
The List shows several choices for 83W. The NBC transponder would be my recommendation. SatelliteGuys.US_TheList - 83.0°W AMC 9 Ku
