My KI-209 VOR/LOC/GS Indicator is averaging about 7 degrees off of calibration
on VOR checks. Its driven by a KX-155 and I'f like to adjust it to within tolerance.
I don't have a manual for it but I know the adjustment screw is behind one of
the two upper panel mounting screws (I think one is the LOC adjustment and one
is the VOR adjustment).

Can anyone tell me which screw is for the VOR radial calibration adjustment?

Thanks -
