Re: South centered G5400???



There are several plans on the web to build your own az/el indicator with
digital displays (especially EME operators).  They're easily calibrated and
available for less than $20.  Probably more accurate if you got one with a
tenths place.

I've thought about doing this by tapping into the the pot wires at the back
of the controller (I don't remember which three wires it is) and putting two
digital displays in a project box to give a better visual indication.
