Unfortunately, it's been several years since I did research and tests with my lrl and I don't remember all the details that are asked of me, very important is the voltage of the lrl power supply, the 7812 requires at least 15V to work correctly, I recommend 18V power supply and calibrate the control led to light up with 15.5V. Regarding the sky effect and the compass effect they are due to excessive amplification so the only remedy is to lower it. In my country, I can not vouch for the others, the greatest sensitivity is proceeding from north to south, the minimum from south to north and an intermediate value east/west and west/east. Regarding the stability of the sensor stage output I have never had problems. I invite other members who have built my lrl to express their opinion.
