When you say towards the left, do you mean fewer windings in the circuit (left in image xxxxx213 that shows the physical picture)?
I think 1150 (higher frequency) to the left (less resonating coil) is the way it should be, so you are going in the right direction by adding the series cap.
I think having the station positions reversed initially was an indication that the antenna capacitance was loading the coil too much.
Antenna loading can be reduced by using a second, smaller coil for coupling the antenna to the main coil.
