[amsat-bb] Azimute pointer on a G-5600 gives a wrond value

Hello thanks for reading,

I recently acquired a Yaesu G-5600 and experience the following:

When I turn the azimuth antenna, then the pointer gives an other value than when I don't turn the antenna.

It lookes that the load on the powersupply causes the pointer to indicate a different value then when there is no load.

Is this a known problem? And is there a way to solve this problem?

Thanks in advance,
