[TowerTalk] Belt Slippage on LM-470 Towers

[paul@w8aef.com]

I have not had any problem with the belt on my '470 slipping, but then we 
don't have cold WX in Arizona <grin>.

It could be the clutch on the driven pulley that is slipping, and that is 
adjustable.  Just keep in mind that the clutch is a safety device, designed 
to slip when the tower is fully extended against the stops.  Slipping 
clutches save broken cables (and destroyed towers).
