[TowerTalk] Yaesu G-1000DXA control box: pointer error

[Eric Scace K3NA]

Hi folks --

   At W1KM the 10m stack is rotated by a Yaesu G-1000DXA.  The stack is 
side-mounted so we only get about 300° of azimuth coverage.

   The control box does not track direction very well.  At the full CCW 
limit (330°), we can set the pointer for the correct direction.  The 
display reads out correctly from NW through E.  Thereafter the indicator 
moves smaller and smaller distances ... so that, by the time the antenna 
is pointing SW, the display indicator is 45° behind (i.e., pointing S).

   Recently this problem became worse.  The indicator no longer tracks 
even in the previously-correct NW-through-E sector.

   We suspect something has gone wrong in the electronics within in the 
control box... but wonder if anyone else has had -- and fixed -- this 
problem.

   Thanks.
