your numbers look OK.
Yes, that is your closest sat highest point in sat arc.
I assume you've set the motor to 0, then lined up everything to 196 on the compass.
Then select Nahuel1 on the list and have the motor drive there.
Make sure you are on active transponder for that sat (I cant get that one at my location due to trees) but lyngsat shows a bunch of them.

maybe someone else familiar with Nahuel1 can comment on whats strong on that sat to pick in order to try to find the signal...
Other than that, it's keep trying in baby steps. I'm not famaliar with coolsat box to help with how to set that thing up.
