[TowerTalk] Effective Moment/K Force & Yaesu rotators

[Frank C. Travanty]

They must have built them good in 1968. My Ham-M turned a TH6DXX from
1968 thru 1998. It was still working fine when I retired it. The pot was
beginning to get scratchy and the terminal strip was corroded, but was
otherwise fine and had never failed during those years. I now have a
2800SDX with a larger array, and will be very dissapointed if it only
lasts 6-7 years.
