[amsat-bb] G5500 position pot

[Norm n3ykf]

500 Ohm 450 degree pot, for a G-5500.

Yaesu is the only option for that exact piece.

Not a standard item. I used a 1k, three turn pot. Using Goody's
rotator controller, analog reference enabled, 3.3V and a two
resistors, it worked just fine. Would not work with Yaesu's controller
box, period.

It would, however, work mechanically and provide a reasonable
reference, electrically.


Using a 540 degree pot in a 360 degree rotator (5500 pot in a 5400)
might present some problem. I.E. calibration issues with the control
box.
