TT (and rotator) experts- Anyone have any experience with "unsticking" a Hy-Gain HDR-300 rotator? Seems to be stuck at one end of the travel (0 degrees) on the CCW limit switch. Solenoid buzzes and releases OK. Both limit switches look OK and make audible "click" when manually depressed. Appreciate any and all input 73's, Craig WA6OXK
