[TowerTalk] HDR300 rotor repair

[john at kk9a.com]

Unless things have changed since I owned my HDR300s, the biggest wear was
from the poor fitting key on the shaft and the mast bracket. If it is sloppy
the antenna will rock back and forth in the wind a considerable amount. Also
I had one unit fill with water when the top seal went bad so I would look at
that.  They are pretty easy to work on, I purchased and machined many parts
for the two that owned during the short time that I used them.

Is anyone familiar with a good place to have an HDR 300 rotor gone through (

inspected, repaired, tested) ? I have one that was reported to work when
taken 
down but it was up for several years and had decent sized antennas on it so
I 
would like to have it gone through. Thank you, Joe N4JBK
