Hi All,
I'm posting this here because the Fox Delta Yahoo group seems to be quite inactive and I haven't received any responses that might fix this problem yet.
On my ST2, the azimuth indication doesn't stay at one heading. Instead, if it should be on say 210 degrees, it will rapidly change from 207, to 223, to 215, to 205, etc.. Fluctuating within a 15-20 degree range. After being in contact with Dinesh and having replaced the PIC and crystal, the problem persists.
Any ideas of what could be causing this?
Crap in the position-sensor pot? Bad voltage regulation feeding the high side of the position-sensor pot? Faulty lead or connection? Does it get worse if you shake the lead coming out of the control head, or going into the rotator?
