[TowerTalk] TIC Potentiomenter

[Fred Sanborn]

John,
     I recently bought a few Vishay 534-11501  from Mouser 594-53411501  
as a replacement.  However, I am already having problems with what I 
believe is an intermittent wiper after only 7 months.  Part of the 
problem may be partly due to that I have not been turning the antenna 
much at all for months at a time.  After applying voltage on the motor 
lines to get the pot wiper moving it started working a bit better with 
only a bit of intermittent operation.  After a few more weeks of 
inactivity I tried turning it and got the no motion error message on the 
RT-21 again.

     I think using a pot for direction is the worst part of the TIC ring 
system.  Has anyone ever made a mod to the TIC and use a magnetic reed 
sw for direction.  How difficult would that be?  I have a Alfa Spid that 
has a reed sw with a RT-21 controller and it just keeps working.
