[TowerTalk] Indicator wiper issues

[Tony Brock-Fisher K1KP]

I had this failure too, but I don't think it was vibration. I think this 
is partially due to a design issue on the pot. Earlier (pre-MFJ) pots 
had thin phosphor-bronze wipers riding on the hard nichrome resistance 
wire element. More recent ones, seen at the MFJ display at Dayton a few 
years ago, now have a thicker pad of another material soldered to the 
end of the wiper arm. So somebody at Hy-Gain/MFJ knows something about 
this failure mode.
