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.
