[TowerTalk] T2X rotor problem info

[Dave Thompson]

  Gang,  I got new manual and pin out from Ken Goodwin and here is what happened to my rotor.

 Thanks Ken for the manuals and rotor unit pin out.  I plan on getting the two manuals I have (both are older CDE manuals and compare and pull new info in the later Telex/Hy-Gain manual.  I plan to check out the rotor from the shack by following the test procedures.  The start capacitor in the control box was new in 2006 as supplied by the late Bill Wall KC4UZ who owned Antenna mart at that time.

The 40 meter beam was installed and the rotor had to be rewired on the tower to mount it on the DX Engineering plate below the DX Engineering thrust bearing.  The tower man had me rotate the T2X to indicate North and he rotor moved smoothly from the last position to North.  Then the mast was tightened up and the lower beam was installed.  A tree man was present and turned the antennas by hand through 360 degrees o determine which tree branches might interfere with rotation.  He found two tree branches that seemed to be in the way of rotation of the top antenna at 80 feet which was the 2 el Cushcraft 40.  My mistake was not to try and rotate the beams right then.  After the tower crew left I decided to move the beams to the NNE which would have allowed me to work a few stations while awaiting the tree man to come back with his chain saw and helper to clear the branches. 

I tried turning the rotor from North by east and nothing happened but I could hear the motor start.  I then turned it West and it rotated to about 350 degrees but then the direction indicator went to South by West (cut off) and the motor starts by no further rotation occurred.

I will also forward this to towertalk for their ideas.  I will test out the rotor from the ground as per the manual. Ideas on what the problem might be appreciated. I am hoping this is just a problem with the rewiring of the terminal strip on the tower as no previous problem with rotation and no brake lock up.
