sky and compass effects are always unwanted, but are useful to adjust the LRL to the maximum sensitivity that corresponds to the point before the start of the effect. To get what decrease the value of R10 in the version with 1 LED (from 220K to 100K or 47K) or in the 3 LED version change R1 from 150K to 100K and R2 from 220K to 470K. It is possible that more short antennas are less susceptible to the compass effect.
