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.
