If it's a ham 4, or similar, why would you sit with your finger on the 
rotate button for several minuets?

 Aren't you watching the direction indicator?

 My good friend Hal, WA7EGA simply put black tape on the direction meter 
that
 showed the maximum rotation. Worked just fine in his contest station for 
many years.
