[amsat-bb] Yaesu G-5500 Elevation read

[Erich Eichmann]

Hello Vincenzo,
some years ago I had the same problem with my KR-500 elevation rotor. 
The reason: The little wheel on the shaft of the potentiometer that 
rotates the poti when the rotor is moved slipped on the shaft and the  
poti remained in the left end position. The wheel is attached to the 
shaft with an allen screw to prevent it from slipping. The screw had 
loosened. All I had to do was tighten the screw.
But as Jarda, OK2GZ, suggested:  First measure  the resistance between 
the 3 wires  to the potentiometer at the control box to see whether one 
of the wires is broken or disconnected.

73s, Erich, DK1TB
