Your motor's bracket setting is ALWAYS set to your latitude.
In your case, 40.1, as Sagirma put in bold letters in his response.
Your dish is the only elevation you should adjust when you are dialing things in. That's why I asked what kind of motor you have - it makes the bracket setting on the dish different depending on what motor you have.
He is guessing you have
HH90 motor, thus the 38.7 suggestion for that setting.
