I got a copy of the correct schematic.
Thanks to all who replied.

Is there a reason why the HAM-IV Manual I downloaded from the MFJ site does not show the Calibrate Switch on the schematic ??
It seems a simple enough thing to show, it has been part of the Control Box for eons !! Very discouraging ....

Dick, 
This is because there is no calibrate "SWITCH" in the new Ham IV Rotator controllers.  The 5k Ohm potentiometer is there for calibration purposes.  The written procedure for calibrating the "newer" Ham IV rotators has also changed.  I have an older manual, with the "switch", if you would like a copy.
