Some weeks ago, my elevation rotor KR-550 "froze". It does not move, and the elevation is fixed at 45 degrees.
The elevation rotor is more than 10 years old, and this kind of problem seems to be "normal" with this rotor type. A search on the net showed that other hams have had the same problem, e.g. PA1IVO. I am now going to repair it following his advice.
My first EME QSO is unlikely to happen until the rotor is fixed.
